Two boxes, connected by a cord, are pulled horizontally on a frictionless surface with an applied force of 40.0 N. Box A has a
mass of 10.0 kg; Box B has a mass of 12.0 kg.
(Hint: you have Fn & Fg for BOTH vertically, you have decide on the horizontal forces.)
a. Draw a free body diagram for box A.
b. Draw a free body diagram for box B.
c. Find the acceleration, a, of the two boxes.
d. Find the tension, FT, in the cord connecting boxes A and B

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.
