Imagine two billiard balls on a pool table. ball a has a mass of 7 kilograms and ball b has a mass of 2 kilograms. the initial velocity of the ball a is 6 meters per second to the right, and the initial velocity of the balloon b is 12 meters per second to the left. when the two balls hit each other, what will happen if it is a perfectly inelastic collision? what can you say about the total momentum before and after the collision?

The pressure proportional to the area a- inversely b- directly c- increase d-decrease

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.
