Moving a magnet inside a coil of wire will induce a voltage in the coil. how is the voltage in the coil increased?
a. by moving the coil of wire slowly, and keeping the magnet stationary
b. by holding the magnet absolutely still
c. by moving the magnet inside the coil of wire more slowly
d, by moving the magnet inside the coil of wire more rapidly

A100 kg running back runs at 5m/s into a stationary linebacker. it takes 0.5 for the running back to be completely stopped

The force needed to overcome static friction is usually less than that needed to overcome kinetic friction.true or false?

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
