Areal heat engine operates between temperatures tc and th. during a certain time, an amount qc of heat is released to the cold reservoir. during that time, what is the maximum amount of work wmaxthat the engine might have performed? express your answer in terms of qc, th, and tc.

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.
