This graph shows that the orbit of a binary pulsar is decaying just as general relativity predicts it should (notice the agreement between data and theory). What is the significance of this particular result?
A) It supports the prediction that orbiting stars will radiate energy outward in the form of gravitational waves. B) It tells us that time runs slower in this binary system than on Earth. C) It confirms that gravitational lensing can really occur. D) It shows that general relativity can explain all known natural phenomena.
A foul ball is hit straight up into the air with a speed of 30 m/s, and air resistance is negligible
(a) Calculate the time required for the ball to rise to its maximum height. (b) Calculate the maximum height reached by the ball above the point where it hit the bat. (c) Determine the times at which the ball passes a point 25 m above the point where it was hit by the bat. (d) Explain why there are two answers to part (c).
If a bar magnet is falling through a loop of wire, the induced current in the loop of wire sets up a field which exerts a force on the magnet. This force between the magnet and the loop will be repulsive when:
a. the magnet enters the loop. c. never. b. the magnet is leaving the loop. d. the magnet is halfway through.
