This concept of closed loop wire experiences a changing magnetic field and flowing of current is related to the Faraday's law of electromagnetic induction.
Why there is a current flow whenever there is a change in magnetic field in a closed loop of wire?When ever there is a bar magnet inside the wire and the magnet moves relative to the wire there will be an EMF generated in the coil and current can be flown.
similarly by reversing the process if the magnet remains stationary and the coil is moved then again the emf and the current generated in the coil which is called as electromagnetic induction.
This is the basic principle of transformers,generators,motors .
Thus when a closed loop of wire experiences a changing magnetic field a voltage and therefore current is produced.

A 10 ohms resistor, 10 mh inductor, and 10micro farad capacitor are connected in series with a 10khz voltage source. The rms current through the circuit is 0.20A. Find the rms voltage drop across each of the three elements
Answer:
126 V
Explanation:
The computation of the rms voltage is shown below:
= I × R
=(.2) × (10)
= 2 V voltage drop across capacitor
= I × 1 ÷ (?C)
= I ÷ (2 × pi × f × C)
= (.2) ÷ (2 × pi × 10,000 × 10 × 10^-6)
= .318 V voltage drop across inductor
= I × ?L
= I × 2 × pi × f × L
= .2 × 2 × pi × 10,000 × .010
= 126 V

An experiment is designed to investigate the relation between the pressure and temperature in a tank that has a constant volume and mass. (The equation of state for air is pV=m R T, where p is the pressure, V is volume, m is mass, R is the gas constant, and T is the temperature.) A polynomial relation was suggested for the relation between p and T. You noticed that as you increase the order of the polynomial the error between the curve fit and the measured data decreases. What polynomial order is best to use
Answer:
3rd order polynomial
Explanation:
Given that the increase in the order of the polynomial the error between the curve fit and measured data will decreases hence :
The polynomial order that is best to use is the 3rd order polynomial, this is because using a 3rd order polynomial will produce a less variance and a low Bias
1. In a demonstration, Mr. K stretches a steel wire to a length 1.23 meters and braces both ends so that they are not free to vibrate. He attaches a fancy piece of equipment which he calls a mechanical oscillator to the wire and explains how it works. Then Mr. K turns the oscillator on and tunes the frequency to 588 Hz. To the amazement of the class, the wire begins vibrating in the sixth harmonic wave pattern. a. Determine the speed of waves within the wire. b. Determine the frequency at which the wire will vibrate with the first harmonic wave pattern. c. Determine the frequency at which the wire will vibrate with the second harmonic wave pattern.
Answer:
a.241.08 m/s b. 196 Hz c. 392 Hz
Explanation:
a. Determine the speed of waves within the wire.
The frequency of oscillation of the wave in the string, f = nv/2L where n = harmonic number, v = speed of wave in string, L = length of string = 1.23 m.
Since f = 588 Hz which is the 6 th harmonic, n = 6. So, making v subject of the formula, we have
v = 2Lf/n
substituting the values of the variables into v. we have
v = 2 × 1.23 m × 588Hz/6
v = 241.08 m/s
b. Determine the frequency at which the wire will vibrate with the first harmonic wave pattern.
The first harmonic is obtained from f when n = 1,
So, f = v/2L = 241.08 m/s ÷ 1.23m = 196 Hz
c. Determine the frequency at which the wire will vibrate with the second harmonic wave pattern.
The second harmonic f' = 2f = 2 × 196 Hz = 392 Hz
The Pacific Plate is moving 29 mm/year toward the north and 20 mm/year toward the west relative to the North American Plate. Show how to use geometry and the Pythagorean Theorem to calculate the total relative motion toward the northwest.
Answer:
7 mm per year
Explanation:
It is given that :
The Pacific plate is moving towards north at = 29 mm per year
The Pacific plate is moving towards west at = 20 mm per year
We have to calculate the total relative motion towards the northwest.
So we have to find the resultant of the two motions.
Since the two movements are perpendicular, therefore the angle between the two motions is 90 degree.
Therefore, finding their resultant,
[tex]R^2=(29)^2+(20)^2[/tex]
[tex]R^2=(49)^2[/tex]
R = 7
Therefore, total relative motion towards the northwest is 7 mm per year.

C.
Turn on the flame for 30 seconds each minute for 2 minutes, and cut a large hole in the balloon material to allow excess air out.
D.
Turn on the flame for 30 seconds each minute for 10 minutes to decrease the density of the air inside the balloon.
Answer:
The answer is B. :)
Explanation:
The hot air balloon reaches the highest height turn on the flame for 10 seconds each minute for 2 minutes and cut a large hole in the balloon material to allow excess air out.
What is a hot air balloon?Because hot air rises, hot air balloons work. By using the burner to heat the air inside the balloon, it becomes lighter than the cooler air on the outside.
As a result, the balloon floats upwards, as if it were in the water. Obviously, allowing the air to cool causes the balloon to slowly deflate.
Hot air balloons use a flame that can turn on and off to heat air inside a large balloon. The balloon is attached to a basket that can carry people or cargo as it is lifted off the ground and floats in the air.
Turn on the flame for 10 seconds each minute for 2 minutes, and cut a large hole in the balloon material to allow excess air out.

2. A 4.0 kg magnetic toy car traveling at 3.0 m/s east collides and sticks to a 5.0 kg toy magnetic car also traveling at 2.0 m/s east. Calculate the final speed and direction of the magnetic car (coupled) system?
Answer:
2.44 m/s due East
Explanation:
From the question given above, the following data were obtained:
Mass of 1st car (m₁) = 4 Kg
Velocity of 1st car (u₁) = 3 m/s
Mass of 2nd car (m₂) = 5 Kg
Velocity of 2nd car (u₂) = 2 m/s
Final velocity (v) =?
The final velocity can be obtained as follow:
v(m₁ + m₂) = m₁u₁ + m₂u₂
v(4 + 5) = (4×3) + (5×2)
9v = 12 + 10
9v = 22
Divide both side by 9
v = 22/9
v = 2.44 m/s
Thus, the final velocity is 2.44 m/s.
Since both cars was moving due East before collision, and after collision, they stick together, then their direction will be due East.

One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 25 m/s. The masses of the two objects are 3.0 and 8.0 kg. Determine the final speed of the two-object system after the collision for the case when the large-mass object is the one moving initially and the case when the small-mass object is the one moving initially.
Large object moving, small object at rest:
v = 18.18m/s
Small object moving, large object rest:
v= 6.81m/s
Explanation:
p = mv
m1•Vi1 + m2•Vi2 = m1•Vf1 + m2•Vf2
First Scenario (large object moving):
For small object,
p=mv
p= 3kg • 0 = 0
For large object,
p= mv
p= 8kg • 25m/s = 200kg•m/s
Combined,
p1+p2 (small object + large object) = 200m/s
After the collision, there is one mass,
new mass is 8kg + 3kg = 11kg
So now , p = mv again. In this case
200m/s = (11kg)•v
v = (200kg•m/s)/(11kg) = 18.18 m/s
Second Scenario (small object moving):
p1v1 = 3kg•25m/s = 75kg•m/s
p2v2 = 8kg•0 = 0
p1v1 + p2v2 = 75kg•m/s
New mass = 8kg+ 3kg = 11kg
p = mv
75kg•m/s = 11kg•v
v = (75kg•m/s)/11kg = 6.81m/s
