CAN ANYONE PLS HELP me, 25 points! Question (1) dt= -3 t+6 is the equation of motion for a moving object, at what instant the object will reverse its direction of motion?

Hint: Substitute d=0 m in the above equation and solve for t.

What will a positive and a negative charge do if they are separated from each other?

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?

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.
