You are target shooting using a toy gun that fires a small ball at a speed of 15 m/s. When the gun is fired at an angle of 33 ∘ above horizontal, the ball hits the bull's-eye of a target at the same height as the gun. Then the target distance is halved.

At what angle must you aim the gun to hit the bull's-eye in its new position?

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.
