(e) What is the net electric flux through the cube?

Please answer the following questions with a moderate amount of detail:

1. In 1921, Albert Einstein received a Nobel prize for his interpretation of an experiment that could not be explained using Maxwell

A 480 kg horse pulls a 260 kg cart with a constant acceleration of 0.800 m/s2. Assume the only force acting on the horse comes from the cart pulling on it.

(a)What force does the horse extert on the cart?

______ N

(b)What force does the cart exert on the horse?

_______N

(c)What is the net force acting on the horse?

______N

a) In a proton at one certain moment, the down quark has a strong color charge of red. What are the color charges of the two up quarks? (Type each color in lowercase with a space between each one.)

(d) In a pi meson at a certain time one quark has a red color. What is the color of the antiquark at that time?

A home run is hit in such a way that the baseball just clears a wall 14.0 m high, located 128 m from home plate. The ball is hit at an angle of 33.0

A person with mass mp=80 kg is standing at rest on a horizontal, frictionless surface holding a ball of wet clay with mass mg=10 kg . In front of the person is a large block with mass M=20 kg at rest next to a spring with stiffness k=100 N/m . The person throws the ball horizontally, it sticks to the block, and then ball and block slide and compress the spring a distance 1=0.75 m away from equilibrium before the ball-block springs back toward the person. (Assume the distance the ball is thrown is short, so that we can ignore the vertical component of its velocity.)

a) Find v P1 (the speed of the person after the ball was thrown)

b) Find Vs (the speed at which the person, ball, and block move after the ball and block bounced back off the spring and collided with the person)

c) If it takes 0.2 seconds for the person and the ball-block to get to the same velocity, find the impulse on the person due to the ball-block. AND find the force on the person due to the ball-block,

(Please be careful in your answer in part b because the person is also moving after he throws the ball. So, this will effect the final answer for their overall speed. And, please don't copy from others. They are all wrong. Thanks.

1.A circuit of resistors connected in series is plugged in a 120 V outlet. What can you tell about the voltage on each of resistor and current in each resistor?

2.A circuit of capacitors connected in parallel is plugged in a 120 V outlet. What can you tell about the voltage on each capacitor and current in each capacitor?

A 82.9-kg man is standing on a frictionless ice surface when he throws a 1.70-kg book horizontally at a speed of 13.0 m/s. With what speed does the man move across the ice as a result? Give your answer in m/s, and be sure to use three significant figures in your answer.

An infinitely long line of charge has linear charge density 5.00×10⁻¹² C/m . A proton (mass 1.67×10⁻²⁷ kg , charge e) is 14.5 cm from the line and moving directly toward the line at 2500 m/s .

Calculate the proton’s initial kinetic energy.

How close does the proton get to the line of charge?

Please show how you got the answer so that I understand. :)

Explain whether it makes a difference to the net flux of a system if the shape of the object that it encloses changes. Be sure to explain why.

9. A cue ball traveling at 0.65 m/s hits the stationary 8-ball, which moves off with a speed of 0.22 m/s at an angle of 40° relative to the cue ball's initial direction. Assuming that the balls have equal masses and the collision is inelastic, what will be the speed of the cue ball?

2. (a) Write down the Time Dependent Schr

An electroscope has a charge of −3.9 µC while your finger has a charge of 4.2 µC. You touch the electroscope with your finger and discover that the charges of your finger and the electroscope are now the same. In this process, electrons were transferred from the electroscope to your finger. How many electrons were transferred in order for your finger and the electroscope to have the same charge?

---I got 4.05 but this isn't right
