How do you calculate the total resistance in a series circuit with more than one resistor
Answers
Answer:
You add up all the individual resistances of the resistors in the series circuit to get the total resistance of the circuit
Explanation:
A series circuit is a circuit that has most of its components connected end-to-end
following what was stated above, in a series circuit, the resistors are connected end to end. This means that the current that flows out from one of the resistors flows into the next one. As a result of this, the current through all the resistors is the same.
To get the total equivalent resistance in a series circuit, you add up all the individual resistances of the resistors in the series circuit. This should give you the total resistance in the circuit.
i.e
Total resistance = R1 + R2 + R3 ....

What do diffraction and refraction have in common? They both involve interference. They both involve wave interactions. They both involve reflection. They both involve construction.
Answers
Answer:
They both involve wave interactions.
Explanation:
Diffraction is defined as the bending of waves around obstacles. Refraction can be defined as the bending of the light when it transfers from one substance to another. The main similarity between the diffraction and refraction is that both involves the interaction of the waves with the substance and also causes the waves to bend and change their direction. Hence, they both involve wave interaction is the correct option.
What diffraction and refraction have in common is that they both involve wave interactions. This is further explained below.

→ a) The magnitude of the electrostatic force between the eggs increases, and they repel each other.
→ b) The magnitude of the electrostatic force between the eggs decreases, and they repel each other.
→c) The magnitude of the electrostatic force between the eggs decreases, and they attract each other.
→d) The magnitude of the electrostatic force between the eggs increases, and they attract each other.
Answers
Answer:
I think the answer is C but I'm probably wrong.
According to Coloum's law, when two charged eggs are brought closer, the magnitude of the electrostatic force between the eggs increases, and they attract each other. Hence, option D is correct.
What is Coloumb's law?Coloumb's law equals the magnitude of charges and distance of charges. It gives force of attraction or repulsion between the charged bodies. Like charges repel each other and unlike charges attract each other.
Coloumb's law states that the force of attraction or repulsion between charged bodies is directly proportional to the product of charges and inversely proportional to the square of distance between them.
The force of attraction or repulsion is given by,F = q₁×q₂ / r². q₁,q₂ is the product of charges and r is the distance of seperation of charges. The force decreases with increase of distance as distance and force are inversely proportional to each other.
From the given, two metal egg is given, one is with positive and other is negatively charged metal egg. When two metal eggs are brought closer, they attract each other as the metal eggs are oppositively charged.
When two oppositvely charged metals are brought closer, the distance of seperation of two metal eggs decreased. When distance of seperation decreases, electrostatic force increases.
Hence, as the metal eggs come closer to each other without touching the distance decreases with increase of electrostatic force and they are unlike charges, thus they attract each other. Hence, the correct option is D.

A 74.2 kg teenager slides down a frictionless slide that has an angle of inclination of 38˚. What is the magnitude of the acceleration of the teenager down the slide?
Answers
Answer:
Explanation:
This is one-dimensional motion on an incline which makes it so much more funner :/
The equation for this is
w*sinθ - f = ma which is just a fancy version of Newton's second law that says that the sum of the forces acting on an object are equal to that object's mass times its acceleration.
w is the weight of the teen which is also the normal force, [tex]F_n[/tex]. Therefore,
[tex]w=F_n=mg[/tex] where m is mass and g is gravity:
[tex]w=F_n=(74.2)(9.8)[/tex] and we need 2 sig figs for this since there are 2 in 9.8:
w = 730N
Since there is no friction in this problem, the value for f, frictional force, is 0, making our job a bit shorter. Filling in the main equation:
730sin38 - 0 = 74.2a
Since the left side is subtraction and we will eventually have to divide, and the rules for subtraction/addition are different from those for multiplication/division, we will have to subtract first, get the correct number of sig figs for that difference, and then divide, following the rules for division.
730sin38 will have 2 sig figs which is 450. Now
450 - 0 = 74.2a and
450 = 74.2a and divide to 2 sig figs:
a = 6.1 m/s/s

Answers
Answer:
The spring constant will be "1333.33 N/m".
Explanation:
The given values are:
Mass,
m = 1.2 kg
Displacement compression,
x = 0.15 m
Block's velocity,
[tex]v_i=5 \ m/s[/tex]
As we know,
⇒ [tex]E_i=E_f[/tex]
or,
⇒ [tex]K_i+v_i=K_f+v_f[/tex]
⇒ [tex]\frac{1}{2}mv_i^2+0=0+ \frac{1}{2}Kx^2[/tex]
So,
⇒ [tex]K=\frac{mv_i^2}{x_2}[/tex]
On substituting the values, we get
⇒ [tex]=\frac{1.2\times 5\times 5}{0.15\times 0.15}[/tex]
⇒ [tex]=\frac{30}{0.0225}[/tex]
⇒ [tex]=1333.33 \ N/m[/tex]

Explanation:

The total force on charge q(3) is 1125 x [tex]10^{-3}[/tex] Newton
We have three charges in a straight line.
We have to find the force on charge q3 due to charge q1 and q2.
State Coulomb's law.The force between two point charges is directly proportional to the product of the magnitude of two point charges and inversely proportional to the square of the distance between them. Mathematically-
[tex]F = \frac{1}{4\pi\epsilon_{o}}{\frac{qQ}{r^{2} } } }[/tex]
We have -
[tex]q_{1} =q_{2} =q_{3} = -5 \times 10^{-6} C[/tex]
The distance between -
[tex]q_{1}\;and\;q_{2} = q_{2} \;and\;q{3}[/tex] = 0.5 m
Now, Force on charge q(3) due to charge q(1) -
F(1 → 3) = [tex]\frac{1}{4\pi\epsilon_{o}}{\frac{5\times 10^{-6} \times 5\times 10^{-6} }{1^{2} } } } = 9\times 10^{9} \times 25 \times 10^{-12} = 225\times 10^{-3}[/tex] N (repelling force)
Force on charge q(3) due to charge q(2) can be calculate similarly as -
F(2 → 3) = 900 x [tex]10^{-3}[/tex] N(repelling force)
Now, both the forces are in same direction, so we can add them algebraically -
[tex]F_{net}[/tex] = F(1 → 3) + F(2 → 3) = 1125 x [tex]10^{-3}[/tex] N
Hence, the total force on charge q(3) is 1125 x [tex]10^{-3}[/tex] Newton
Hence, the wavelength of light in nano meters is 0.0177 x nm.

En una feria, se gana una jirafa de peluche lanzando una moneda a un platito, el cual está sobre una repisa más arriba del punto en que la moneda sale de la mano y a una distancia horizontal de 2.1 m desde ese punto (figura 3.41). Si lanza la moneda con velocidad de 6.4 m>s, a un ángulo de 60° sobre la horizontal, la moneda caerá en el platito. Ignore la resistencia del aire. A) ¿A qué altura está la repisa sobre el punto donde se lanza la moneda? B) ¿Qué componente vertical tiene la velocidad de la moneda justo antes de caer en el platito?
Answers
Answer:
A) La altura de la repisa sobre el punto donde se lanza la moneda es de aproximadamente 0,42 m
B) La velocidad de la moneda justo antes de que golpee el platillo es de aproximadamente 0,895 m/s hacia abajo
Explanation:
A) Los parámetros dados son;
La distancia horizontal del plato desde donde se lanza la moneda = 2,1 m
La velocidad con la que se lanza la moneda, u = 6,4 m / s
El ángulo al que se lanza la moneda, θ = 60 °
La componente horizontal de la velocidad, vₓ = 6.4 m / s × cos (60°) = 3.2 m/s
El tiempo que tarda la moneda en recorrer una distancia horizontal de 2,1 m, 't' se calcula de la siguiente manera;
t = 2,1 m/(3,2 m/s) = 0,65625 segundos
Por tanto, la altura de la moneda a 0,65625 segundos se da de la siguiente manera;
y = u × sin (θ) × t - (1/2) × g × t²
En t = 0,65625 segundos, obtenemos;
y = 6,4 × sin (60°) × 0,65625 - (1/2) × 9,81 × (0,65625) = 0,41840044589
La altura de la repisa sobre el punto donde se lanza la moneda, y ≈ 0.42 m
B) La velocidad vertical de la moneda justo antes de que golpee el platillo, [tex]v_y[/tex], se da como sigue;
[tex]v_y[/tex] = u × sin(θ) - g·t
∴ [tex]v_y[/tex] = 6.4 × sin(60°) - 9.81 × 0.65625 ≈ -0.895
La velocidad de la moneda justo antes de golpear el platillo, [tex]v_y[/tex] ≈ 0.895 m/s (hacia abajo)

transverse wave in which the particles of the wave move in a direction perpendicular to the wave motion
O longitudinal wave in which the particles of the wave move in a direction perpendicular to the wave motion
Answers
Answer: longitudinal wave in which the particles of the wave move in a direction parallel to the wave motion
The sound wave is a longitudinal wave in which the particles of the wave move in a direction parallel to the wave motion.
What is a wave of sound?A sound wave can be described as the pattern of distribution caused by the movement of energy that is traveling through a medium, such as air, water, or any liquid or solid matter, etc, as it is traveling away from the source of the sound. There are two types of sound waves:
Longitudinal wave: When the particles of the medium move in a direction parallel to the direction that the wave moves then the wave is known as the longitudinal wave.
Transverse Wave: When the particles of the medium move in a direction perpendicular to the direction that the wave moves then the wave are known as the transverse wave.
As it is given that the sound wave formed by the speaker travels through the air to your ear as a series of compressions and rarefactions of air molecules, therefore, the particles of the medium move in a direction parallel to the direction that the wave.
Hence, the sound wave is a longitudinal wave in which the particles of the wave move in a direction parallel to the wave motion.

you tend to push off with the foot still on the boat.
Newtons 3rd law of motion hold that every action has an equal and opposite reaction.
So, the amount of force you use on your back foot to push yourself onto the dock, has an equal end opposite amount of force going the other way from your sole of your foot, which pushes the boat the other way.

Answers
Answer:
#_photons = 30 photons / s
Explanation:
Let's start by finding the energy of a photon of light, let's use the Planck relation
E = h f
the speed of light is related to wavelength and frequency
c = λ f
we substitute
E = h c /λ
E₀ = 6.63 10⁻³⁴ 3 10⁸/500 10⁻⁹
E₀ = 3.978 10⁻¹⁹ J
now let's use a direct proportion rule. If the energy of a photon is Eo, how many fornes has an energy E = 1.2 10⁻¹⁷ J in a second
#_photons = 1 photon (E / Eo)
#_photons = 1 1.2 10⁻¹⁷ /3.978 10⁻¹⁹
#_photons = 3.0 10¹

A rigid body of moment of inertia 0.5 kg.M^2 rotates with 2 RPM. How much torque is needed to increase the rotation to 10 RPM in 5 seconds.
Answers
Answer:
T = 0.084 Nm
Explanation:
First, we will calculate the angular acceleration:
[tex]\alpha = \frac{\omega_f - \omega_i}{t}[/tex]
where,
α = angular acceleration = ?
ωf = final angular speed = (10 RPM)(2π rad/1 rev)(1 min/60 s) = 1.05 rad/s
ωi = initial angular speed = (2 RPM)(2π rad/1 rev)(1 min/60 s) = 0.21 rad/s
t = time = 5 s
Therefore,
[tex]\alpha = \frac{1.05\rad/s - 0.21\ rad/s}{5\ s}\\\\\alpha = 0.168\ rad/s^2[/tex]
Now, for the torque:
[tex]T = I\alpha[/tex]
where,
T = torque = ?
I = moment of inertia = 0.5 kg.m²
Therefore,
[tex]T = (0.5\ kg.m^2)(0.168\ rad/s^2)\\[/tex]
