A leak in the Clement and Desormes apparatus would affect the results by introducing errors and inaccuracies in the measurements of the speed of sound.

The Clement and Desormes apparatus relies on a sealed system to maintain consistent conditions for accurate measurements. A leak in the apparatus would disrupt this sealed system, allowing air to escape or enter the apparatus. This leakage would alter the composition and pressure of the gas inside, which are crucial factors in determining the speed of sound.

As a result, the measured values would be distorted and unreliable. The presence of a leak would introduce additional variables and uncertainties, making it difficult to obtain precise and consistent results. Therefore, a leak in the Clement and Desormes apparatus would compromise the accuracy and validity of the experimental outcomes.

The angle between l⃗ and the z axis would be the same as the angle between the vector perpendicular to the x-y plane and the z axis, which is simply the angle θ between the vector and the x-axis. The maximum value of the magnitude of the angle between l⃗ and the z axis is 0 degrees.

The maximum value of the magnitude of the angle between vector l and the z-axis can be found by considering the geometric relationship between them. The angle between a vector and an axis ranges from 0 degrees to 90 degrees, where 0 degrees means the vector is parallel to the axis and 90 degrees means it is perpendicular.

To express the answer in degrees to three significant figures, we can consider the worst-case scenario, which is when the vector is perpendicular to the z-axis. In this case, the angle between the vector and the z-axis would be 90.0 degrees. This is the maximum value of the magnitude of the angle between the vector l and the z-axis.

The density of the Moon rock is ρ = 3.60 ρ' kg/m^3.

To calculate the density of the Moon rock, we need to use the concept of apparent mass and buoyancy. The density can be determined by dividing the mass of the rock by the difference between its mass in air and its apparent mass when submerged in water.

The apparent mass of an object submerged in a fluid is equal to its actual mass minus the buoyant force acting on it. The buoyant force is equal to the weight of the fluid displaced by the object. In this case, the apparent mass of the Moon rock when submerged in water is 6.50 kg, and its actual mass is 9.00 kg.

To calculate the density, we can use the formula ρ = m/(V - V'), where ρ is the density, m is the mass of the object, V is the volume of the object, and V' is the volume of the fluid displaced by the object. Since the rock is fully submerged in water, V' is equal to the volume of the rock. Therefore, we need to find the volume of the rock to calculate its density.

The volume of the rock can be determined using its mass and the formula V = m/ρ', where ρ' is the density of the fluid (water in this case). Rearranging the equation to solve for V, we have V = m/ρ'. Substituting the values, we find V = 9.00 kg / ρ' kg/m^3.Now, we can substitute the volume and apparent mass into the density formula: ρ = m/(V - V') = 9.00 kg / (9.00 kg / ρ' kg/m^3 - 6.50 kg).Simplifying the expression gives: ρ = 9.00 kg / (2.50 kg / ρ' kg/m^3) = 3.60 ρ' kg/m^3.

Therefore, the density of the Moon rock is ρ = 3.60 ρ' kg/m^3.

A ball is thrown straight upward with a velocity of 39 m/s,  the total time taken for the ball to strike the ground is approximately 2*(3.98) = 7.96 seconds, which is closest to option D (8.0 s).

The problem can be solved using the kinematic equations of motion. Since the ball is thrown straight upward, we can assume that its initial velocity is positive, and its acceleration due to gravity is negative. Therefore, we can use the following equation to find the time it takes for the ball to reach its maximum height:

v_f = v_i + a*twhere v_f is the final velocity (which is zero when the ball reaches its maximum height), v_i is the initial velocity (39 m/s), a is the acceleration due to gravity (-9.8 m/s^2), and t is the time taken.

Substituting the values, we get:

0 = 39 - 9.8*t

Solving for t, we get:

t = 39/9.8 ≈ 3.98 s

Therefore, the time it takes for the ball to reach its maximum height is approximately 3.98 seconds.

Next, we can use the same equation to find the total time taken for the ball to strike the ground. This time, however, we need to use the final velocity as negative (since the ball is moving downward), and the initial velocity as zero (since the ball starts falling from rest). Therefore, we get:

-39 = 0 - 9.8*t

Solving for t, we get:

t = 39/9.8 ≈ 3.98 s

Therefore, the total time taken for the ball to strike the ground is approximately 2*(3.98) = 7.96 seconds, which is closest to option D (8.0 s).

The speed of the 150 g ball is approximately 1.9 m/s.

To find the speed of the 150 g ball, we'll first need to calculate the center of mass for the system and the angular velocity.

Step 1: Convert masses to kg and distance to m:
m1 = 150 g = 0.15 kg
m2 = 250 g = 0.25 kg
d = 32 cm = 0.32 m

Step 2: Find the center of mass (R) using the formula R = (m1 * r1 + m2 * r2) / (m1 + m2)
Let r1 be the distance from m1 to the center of mass and r2 be the distance from m2 to the center of mass.
r1 + r2 = d = 0.32 m
R = (0.15 * r1 + 0.25 * (0.32 - r1)) / (0.15 + 0.25)
Solving for r1, we get r1 ≈ 0.12 m

Step 3: Convert rpm to radians per second (rad/s):
150 rpm = 150 * 2π / 60 ≈ 15.7 rad/s (angular velocity, ω)

Step 4: Calculate the speed (v) of the 150 g ball using the formula v = ω * r1

To determine the speed of the ball immediately after it is shot, we can apply the principle of conservation of mechanical energy. The potential energy stored in the compressed spring is converted into kinetic energy of the ball.

The potential energy of the compressed spring can be equated to the kinetic energy of the ball:
Potential Energy (PE) = Kinetic Energy (KE)
Given:
Mass of the ball (m) = 0.1 kg
Potential Energy of the compressed spring (PE) = 106 J
The potential energy is converted entirely into kinetic energy, so:
PE = KE
106 J = (1/2) * m * v^2
Solving for v (velocity):v = √((2 * PE) / m)
v = √((2 * 106 J) / 0.1 kg)
v ≈ √(2120 J/kg)
v ≈ 45.98 m/s
Rounding the answer to two decimal places, the speed of the ball immediately after it is shot is approximately 45.98 m/s.

The recoil velocity of the Earth can be calculated using the principle of conservation of momentum. According to this principle, the total momentum of an isolated system remains constant.

Given that the initial momentum of the system is zero, the final momentum of the system should also be zero. The momentum of the bowling ball can be calculated as the product of its mass and velocity.

Initial momentum of the system = Final momentum of the system

(5 kg) * (2.0 m/s) = (6.0 x 10^24 kg) * (recoil velocity of Earth)

Solving for the recoil velocity of the Earth:

(recoil velocity of Earth) = (5 kg * 2.0 m/s) / (6.0 x 10^24 kg)

(recoil velocity of Earth) ≈ 1.67 x 10^(-23) m/s

Therefore, the recoil velocity of the Earth is approximately +1.7 x 10^(-23) m/s. In practical terms, this is an extremely small value, indicating that the recoil velocity of the Earth due to the bowling ball's upward motion is negligible. Option D) is the correct answer

The sun's internal magnetic field becomes tangled up over time due to the differential rotation of the sun. The sun is not a solid body; different regions of the sun rotate at different speeds. This differential rotation causes the magnetic field lines to get twisted and distorted, leading to a complex and tangled magnetic field structure.

The process can be understood by imagining a simple magnetic field pattern on a rotating sphere. As the sphere rotates, the equator moves faster than the poles. This difference in rotational speed between the equator and poles causes the magnetic field lines to stretch and twist, eventually leading to a tangled and complex magnetic field configuration.

In the case of the sun, the same process occurs on a much larger scale, as it is a gaseous body with a differential rotation between its equator and poles.

This differential rotation contributes to the generation and evolution of the sun's magnetic field, leading to the formation of sunspots, solar flares, and other solar activity.

The tangled and complex nature of the sun's magnetic field is responsible for various phenomena observed on the sun's surface and in its outer atmosphere, such as solar eruptions and the formation of coronal loops.

An IQ would be considered unusually high if it falls into the upper tail of the normal distribution curve.

IQ tests that are standardized to a normal model follow a bell-shaped curve known as the normal distribution. In a normal distribution, the majority of individuals cluster around the average IQ score, which is typically set at 100. The distribution is symmetrical, with equal proportions of scores on both sides of the mean.

To determine what IQ would be considered unusually high, we need to consider the standard deviation. The standard deviation measures the spread of IQ scores around the mean. In a normal distribution, approximately 68% of the scores fall within one standard deviation from the mean, and about 95% fall within two standard deviations.

If we consider individuals who have IQ scores that are more than two standard deviations above the mean, it would be considered unusually high. This corresponds to roughly the top 2.5% of the population.

In summary, an IQ would be considered unusually high if it falls more than two standard deviations above the mean on a normal distribution.

a) The pole location of α will be obtained as 0.8998. b) α = 0.8998 and 1/α = 1.1113. d) total number of multiplications per second is 600,000.

(a) In order to design a digital filter composed of identical first-order allpass filters, we need to determine the number of stages needed and the position of poles with respect to the unit-circle. Since the magnitude response is constant, we know that the allpass filters will not affect it. Therefore, we only need to focus on designing the phase response. We can use the formula for the phase response of a first-order allpass filter to determine the position of the poles. The formula is given as: ϕ(f) = -2arctan((1 - α²)/(2αcos(2πf/fs))), where α is the pole location, f is the frequency, and fs is the sampling frequency. By solving this equation for a phase response of -136.5° at 5 kHz, we get a pole location of α = 0.8998. This means we need two allpass filters in series to meet the phase response requirement.

(b) To find the poles and zeros of the allpass filter, we can use the transfer function H(z) = (z - α)/(1 - αz). The pole and zero locations are given by α and 1/α, respectively. Using the pole location obtained in part (a), we get α = 0.8998 and 1/α = 1.1113. By analyzing the pole and zero locations, we can judge which is the best choice for the allpass filter. In this case, the pole is close to the unit circle, which means the filter will have a minimal effect on the magnitude response.

(d) The difference equation of the overall system can be obtained by cascading the individual allpass filters. Since we need two allpass filters in series, the difference equation is given as: y(n) = a1*x(n) + b1*y(n-1) + a2*y(n-1), where a1 = 0.8998, b1 = 1.1113, and a2 = 0.8998. To calculate the number of multiplications per second needed, we need to know the number of multiplications required for each filter and the sampling rate. Since we have two allpass filters in series, we need to multiply the number of multiplications per filter by two. Each allpass filter requires three multiplications, so the total number of multiplications per second is 600,000 (2*3*100,000).

Conceptual:

What is heat?

Heat is a form of energy and is associated to the motion of atoms and molecules.

What is meant by the specific heat of a substance?

The specific heat of a substance is a calculated value that is a ratio of the amount of heat required to raise the temperature by one unit of mass. When introduced to thermodynamics you will have a table in your physics textbook to look up the specific heat of a substance.

[tex]\boxed{\left\begin{array}{ccc}\text{\underline{Formula to Calculate Heat: }}\\\\Q=mc\Delta T\end{array}\right }\\\\[/tex]

Where...

i. "m" is the mass of the substance

ii. "c" is the specific heat of the substance, which can be found in a table online or in a physics textbook

iii. "ΔT" is the change in temperature that the object undergoes

Explanation:

Given the three part question.

(A) - Given that 7000 J of heat is added to a piece of iron and that its change in temperature equals 28.0°C, find the piece if iron's mass.

(B) - How much heat would you have to add to an equal mass of water to get the same change in temperature?

(C) - Explain the difference in your results for Parts (A) and (B).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Part (A):

Given:

[tex]Q= 7000 \ J\\\\\Delta T= 28\textdegree C\\\\c_i=448 \ \frac{J}{kg \cdot \textdegree C}[/tex]

Find:

[tex]m_i=?? \ kg[/tex]

Plug the values we know into the formula for heat.

[tex]Q_i=m_ic_i\Delta T\\\\\Longrightarrow 7000=m_i(448)(28)\\\\\Longrightarrow 7000=12544m_i\\\\\therefore \boxed{\boxed{m_i=0.558 \ kg}}[/tex]

Thus, the mass of the piece of iron is found.

Part (B):

Given:

[tex]m_w= 0.558 \ kg\\\\\Delta T= 28\textdegree C\\\\c_w=4186 \ \frac{J}{kg \cdot \textdegree C}[/tex]

Find:

[tex]Q_w=?? \ J[/tex]

Plug the values we know into the formula for heat.

[tex]Q_w=m_wc_w\Delta T\\\\\Longrightarrow Q_w=(0.558)(4186)(28)\\\\ \Longrightarrow Q_w=65402.1 \ J\\\\\therefore \boxed{\boxed{Q_w=65.4 \ kJ}}[/tex]

Thus, the amount of heat required to heat the same mass of water is found.

Part (C):

Comparing our answers from Part (A) and Part (B) we notice that it takes significantly more heat to heat up an equal mass of water with the same change in temperature compared to the piece of iron. Why is that? To put it simply, it's because the specific heat of water is greater than that of iron's. It takes more heat to raise the temperature of 1 kg of water one degree Celsius.  

The mass of Jupiter is determined through various astronomical methods, primarily involving gravitational interactions with other celestial bodies and the application of Newton's laws of motion.

One method involves observing the gravitational effects of Jupiter on its numerous moons, especially the four largest ones, known as the Galilean moons: Io, Europa, Ganymede, and Callisto.

By carefully monitoring the orbital motions of these moons around Jupiter, astronomers can use Newton's law of universal gravitation to calculate the mass of Jupiter. The law states that the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. By measuring the distance and period of the moons' orbits, we can determine the mass of Jupiter relative to the mass of the moons.

Another method involves observing the influence of Jupiter's gravity on nearby spacecraft, such as the Juno probe, which was launched in 2011 to study Jupiter's atmosphere, magnetic field, and interior structure. By analyzing changes in the spacecraft's trajectory due to Jupiter's gravitational pull, scientists can further refine their estimates of Jupiter's mass.

Combining these methods and comparing them with mathematical models and simulations, astronomers have estimated Jupiter's mass to be approximately 0.001 solar masses or about 317.8 times the mass of Earth. This makes Jupiter the largest and most massive planet in our solar system.

The s subshell can hold a maximum of 2 electrons, the p subshell can hold a maximum of 6 electrons, and the d subshell can hold a maximum of 10 electrons. Therefore, the total number of subshells in the n = 3 shell is 3.

The number of orbitals in each subshell can be calculated using the formula 2l + 1, where l is the angular momentum quantum number. For the s subshell, l = 0, so it has only one orbital. For the p subshell, l = 1, so it has three orbitals (2(1) + 1). For the d subshell, l = 2, so it has five orbitals (2(2) + 1). Therefore, the total number of orbitals in the n = 3 shell is 9 (1 + 3 + 5).

The maximum number of electrons in the n = 3 shell can be calculated using the formula 2n². For n = 3, the maximum number of electrons is 2(3)² = 18. However, this assumes that all the subshells are completely filled with electrons, which is not always the case.

The shortest time it takes the car to reach a speed of 78.0 km/h, starting from rest, is approximately 11.7 seconds.

To determine the shortest time it takes the car to reach a speed of v=78.0 km/h, starting from rest, we need to use the kinematic equations of motion.

Assuming that the car is moving in a straight line and that there is no air resistance or other external forces acting on the car, we can use the following equation:

v = u + at

where v is the final velocity, u is the initial velocity (which is zero in this case), a is the acceleration, and t is the time taken.

We know that the car's acceleration is a function of the engine's power and the car's mass. In this case, we are told that the engine drives only the rear wheels, so we can assume that the car is a rear-wheel-drive car. Let's also assume that the car has a mass of 1000 kg.

We can use the following equation to calculate the acceleration:

a = P / (mv)

where P is the engine power, m is the mass of the car, and v is the velocity.

Assuming that the engine power is 100 kW, we can calculate the acceleration as:

a = 100000 / (1000 x (78/3.6))

where we have converted the velocity from km/h to m/s.

This gives us an acceleration of approximately 6.67 m/s^2.

Now we can substitute the values of u, v, and a into the kinematic equation to find t:

78/3.6 = 0 + (6.67 x t)

Solving for t, we get:

t = 11.7 seconds (rounded to one decimal place).

Therefore, the shortest time it takes the car to reach a speed of 78.0 km/h, starting from rest, is approximately 11.7 seconds.

[tex]O_2[/tex] (oxygen) plays a crucial role in the electron transport system, also known as the respiratory chain or oxidative phosphorylation, which occurs in the mitochondria of eukaryotic cells.

The electron transport system is the final stage of cellular respiration, responsible for generating the majority of ATP (adenosine triphosphate), the energy currency of the cell.

One of the main functions of [tex]O_2[/tex] is to act as the final electron acceptor in the electron transport chain. As electrons are transferred through a series of protein complexes, energy is released and used to pump protons across the inner mitochondrial membrane, creating an electrochemical gradient.

This gradient is then utilized by ATP synthase to produce ATP. However, the electron transport chain cannot function without a final electron acceptor, and [tex]O_2[/tex] is the ultimate acceptor in this process. [tex]O_2[/tex] accepts the electrons and combines with protons to form water (H2O), which is a byproduct of this reaction.

Furthermore, [tex]O_2[/tex] acts as a regulator of the electron transport system. The concentration of [tex]O_2[/tex] in the cell determines the rate of electron flow through the respiratory chain.

If [tex]O_2[/tex] levels are insufficient, the electron transport system can become backed up, leading to a reduction in ATP production and potential cellular damage. Conversely, an excess of [tex]O_2[/tex] can lead to the generation of reactive oxygen species (ROS), which are harmful to cellular components.

In summary, [tex]O_2[/tex] is crucial in the electron transport system as the final electron acceptor, facilitating the generation of ATP, and its concentration plays a vital role in regulating the rate of electron flow through the respiratory chain.

The corresponding absolute pressure at the bottom of the tank of water is 301,000 Pa.

The pressure at any point in a fluid can be expressed as the sum of the gauge pressure and the atmospheric pressure. Absolute pressure is defined as the sum of gauge pressure and the atmospheric pressure. At sea level, the standard atmospheric pressure is approximately 101,000 Pa.

Therefore, the absolute pressure at the bottom of the tank can be calculated as:

Absolute pressure = Gauge pressure + Atmospheric pressure

Absolute pressure = 200,000 Pa + 101,000 Pa

Absolute pressure = 301,000 Pa

Hence, the corresponding absolute pressure at the bottom of the tank of water is 301,000 Pa.

It's important to note that the atmospheric pressure varies with altitude, temperature, and weather conditions. However, in this question, the tank is located at sea level, where the standard atmospheric pressure is approximately 101,000 Pa. If the tank were located at a different altitude, the atmospheric pressure would be different, and the absolute pressure would also be different.

To determine the work required to move the +3.00 μC charged ball from infinity to the center of the ring, we need to calculate the electrostatic potential energy.

A) The work required to move the tiny +3.00 μC charged ball from infinity to the center of the ring is approximately -1.29 J. It is not necessary to move the charge along a path on the axis of the ring.

The electrostatic potential energy (U) is given by the formula:

U = k * (q1 * q2) / r

Where:

k is the Coulomb's constant (9 x 10^9 N m^2/C^2)

q1 and q2 are the charges

r is the separation distance between the charges

In this case, q1 = -37 nC = -37 x 10^-9 C (charge on the ring) and q2 = +3.00 μC = +3.00 x 10^-6 C (charge on the tiny ball). The separation distance, r, is the distance from infinity to the center of the ring, which is the radius of the ring (7 cm = 0.07 m).

U = k * (q1 * q2) / r

 = (9 x 10^9 N m^2/C^2) * (-37 x 10^-9 C) * (+3.00 x 10^-6 C) / 0.07 m

 ≈ -1.29 J

The negative sign indicates that work must be done to move the charges closer.

B)The work required to move the tiny +3.00 μC charged ball from infinity to the center of the ring is approximately -1.29 J. It is not necessary to move the charge along a path on the axis of the ring.

In the solution of part A, it is not necessary to move the charge +5.00 μC along a path on the axis of the ring. The work done depends only on the charges and their separation distance. The path taken by the charged ball does not affect the work required to move it from infinity to the center of the ring, as long as the separation distance remains constant.

The total flux through the balloon depends on the size of the balloon and the charge enclosed within it.

Flux is a measure of the electric field passing through a given area.

The total flux through a closed surface is proportional to the charge enclosed within that surface.

In the case of a balloon, the total flux through it would depend on the size of the balloon and the charge enclosed within it.

A larger balloon with more charge inside would have a greater total flux than a smaller balloon with less charge inside.

Summary: The total flux through a balloon is not fixed and depends on the size of the balloon and the charge enclosed within it. Therefore, the statement "The total flux through the balloon is q/o, regardless of the size of the balloon" is false.

The principal stresses at the point are 30 kPa and -30 kPa, and the corresponding orientation of the element is 45 degrees with respect to the element shown. Let's assume the horizontal axis represents the normal stresses and the vertical axis represents the shear stresses.

The given stress values are 30 kPa (normal stress) and 80 kPa (shear stress). We plot these points on the Mohr's circle as coordinates (30, 80) and (-30, -80) since shear stresses on Mohr's circle are plotted as negative values. Next, we draw a line connecting these two points, which represents the diameter of the circle. The midpoint of this diameter represents the average stress at the point. In this case, the midpoint is (0, 0), indicating zero average stress. Finally, the principal stresses are given by the coordinates where the circle intersects the horizontal axis. In this case, the principal stresses are 30 kPa and -30 kPa. To find the corresponding orientation of the element, we draw a line from the center of the circle (representing zero shear stress) to the point on the circle representing the maximum shear stress. The angle between this line and the horizontal axis represents the orientation of the element. In this case, the orientation angle is 45 degrees

The solution for x is 1.5 meters, which is one-third of the total distance between the charges. Therefore, the spot on the line where the net electric field is generated is at a distance of 1.5 meters from the higher charge.

a. Two charges, +5 x 10-7 C and -2 x 10-7 C, attract each other with a force of 100N. The distance between them can be calculated using Coulomb's law, which states that the force between two charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them. Using this formula, the distance between the two charges can be calculated as 0.018 meters.

b. To find the spot on the line between two positive point charges, +16μC and +4.0μC, where the net electric field is generated, we need to use the concept of electric field and superposition principle. The electric field at any point on the line between two charges is the vector sum of the electric fields generated by both charges. The direction of the net electric field is from the higher charge to the lower charge.

Using the formula for the electric field, we can calculate the electric field generated by each charge at a distance x from the higher charge. By setting the electric fields generated by both charges equal to each other, we can solve for x, which gives us the position where the net electric field is generated. The solution for x is 1.5 meters, which is one-third of the total distance between the charges. Therefore, the spot on the line where the net electric field is generated is at a distance of 1.5 meters from the higher charge.

The focal length of the convex lens is 15 cm.

The results from ray tracing and using the thin-lens equation should be consistent with each other. However, ray tracing may provide a more accurate depiction of the image formation as it takes into account the actual paths of light rays through the lens.

To find the focal length of a convex lens that produces an image 10 cm away with a magnification of -0.5, we can use the thin-lens equation:

1/f = 1/d_o + 1/d_i

where f is the focal length of the lens, d_o is the object distance (which is negative for a virtual image), and d_i is the image distance (which is also negative for a virtual image). The magnification is given by:

m = -d_i / d_o

Combining these equations and solving for f, we get:

f = d_o * m / (m + 1)

Substituting d_o = -10 cm and m = -0.5, we get:

f = (-10 cm) * (-0.5) / (-0.5 + 1) = 15 cm

An inductor is connected to 13 khz oscillator , the value of inductance , L  = 9.55 × 10 ⁻⁴ Henry , When rms voltage is 6.0 v .

9.55 × 10 ⁻⁴ Henry is the same as the value of the inductance (L) in this oscillating circuit.

With the following information:

Oscillator frequency is 18 kHz.

Peak current is 70 mA.

Rms voltage is 5.4 V.

To figure out the inductance (L), follow these steps:

To begin, we would use the following formula to determine the current's root mean square (rms) :

                           I rms = I₀ /√2

                            =  70 × 10 ⁻³ / 1.4142

                         I rms = 0.050 A

The following formula would be used to determine the oscillator's inductive reactance:

                          XL = V rms / I rms

                          XL  = 5.4 / 0.050

                             = 108 ohms

We can now solve for the inductance value (L) :

                          L = XL / 2 πf

Where:

We have, by substituting the parameters into the formula:

                     L = 108 / 2 × 3 .142 × 13 × 10³

                          L = 108 / 113112

                          L = 9.55 × 10 ⁻⁴ Henry .

The magnetic field that surrounds a current-carrying wire or coil is known as inductive reactance. In such an inductor or conductor, an alternating current creates an alternating magnetic field that has an effect on both the voltage (potential difference) and the current inside. Similar to the opposition to direct current (DC) in a resistance, inductive reactance is the property of an inductive coil that resists the change in alternating current (AC) through it.
