6. A student placed a cardboard box at the
bottom of a hill. The student then released a
ball from a point on the hill. The ball collided
with the box, and the box moved a distance
of 2 meters before both the box and the ball
came to rest. Which change to the initial
conditions would be most likely to result in
the box moving a greater distance?
A. decreasing the mass of both the ball and the
box
B. decreasing the mass of the ball and
increasing the mass of the box
C. increasing the mass of the ball and
releasing it from a lower point on the hill
D. decreasing the mass of the box and
releasing the ball from a higher point on
the hill

Four point charges each having charge q are located at the corners of a square having sides of length a. find symbolic expressions for the following. (a) the total electric potential at the center of the square due to the four charges (use any variable or symbol stated above along with the following as necessary: ke.) vtotal= (b) the work required to bring a fifth charge p from infinity to the center of the square (use any variable or symbol stated above along with the following as necessary: w=

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.
