In an electromagnet, a moving charge creates which of the following?
a. a magnetic field
b. a permanent magnet
c. a magnetic pole
d. nothing

The slotted link is pinned at o, and as a result of rotation it drives the peg p along the horizontal guide. compute the magnitude of the velocity and acceleration of p along the horizontal guide. compute the magnitudes of the velocity and acceleration of p as a function of θ if θ=(3t) rad, where t is measured in seconds.

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

An alien spaceship is 500 m above the ground and moving at a constant velocity of 150 m/s upwards. how high above the ground is the ship after 5 seconds?
