Auniform thin rod of length l and mass m is suspended from one end such that it can rotate freely (about an axis at the rod's end). friction is negligible. the rod is displaced from the vertical by an angle and released from rest. what is the angular velocity and linear velocity of the free end at the lowest point of the swing?

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.
