The sled is pulled up a steeperhill of the sameheightas the hill described above.
how will the velocity of the sled at the bottom of the hill (after it has slid down) compare to that of the sled at the bottom of the original hill?
choose the best answer below.
a. the speed at the bottom is greater for the steeper hill.
b. the speed at the bottom is the same for both hills.
c. the speed at the bottom is greater for the original hill because the sled travels further.
d. there is not enough information given to say which speed at the bottom is faster.
e. none of these descriptions is correct.

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.
