REBOUND HEIGHT Procedure
1. Read the procedure and the safety information, and complete the lab form.
2. Drop a large rubber ball from about 15 cm above a table.
3. Measure and record the ball's rebound height using a meterstick.
4. Repeat steps 2-3 with a small rubber ball.
5. Hold a small rubber ball on top of, and in contact with, the large rubber ball.
6. Release the two rubber balls from the same height, so that they fall together.
7. Measure the rebound heights of both rubber balls.
Analysis
8. Describe the rebound height of each rubber ball when it is dropped by itself.

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop
