A500-turn solenoid, 25 cm long, has a diameter of 2.5 cm. a 10-turn coil is wound tightly around the center of the solenoid. if the current in the solenoid increases uniformly from 0 to 5.0 a in 0.60 s, what will be the induced emf in the short coil during this time?

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy
