Some kids are playing dodgeball, in which they throw squishy balls at each other while trying to avoid being hit themselves. assuming that the collisions between the balls are inelastic, which of the following statements is true if two balls collide with each other? a. neither the kinetic energy nor the momentum of the system is conserved. b. the momentum of the system is conserved, while kinetic energy is not conserved. c. the kinetic energy of the system is conserved, while momentum is not conserved. d. both the kinetic energy and the momentum of the system are conserved.

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.
