A rhinoceros beetle rides the rim of a horizontal disk rotating counterclockwise like a merry-go-round. Assume that the disk is not being driven by an external torue, so that the motion of the beetle can affect the motion of the disk. Required:
a. If the beetle then walks along the rim in the direction of the rotation, will the magnitude of the angular momentum of the beetle-disk system (measured about the rotation axis) increase, decrease, or remain the same (the disk is still rotating in the counterclockwise direction)?
b. If the beetle then walks along the rim in the direction of the rotation, will the magnitude of the angular momentum and angular velocity of the beetle (measured about the rotation axis) increase, decrease, or remain the same (the disk is still rotating in the counterclockwise direction)?

Which of the following is an example of units for speed

Which statement is true? a. kepler's laws apply only to the motion of earth. b. kepler's laws can be used to predict eclipses. c. kepler's laws are true for a central force that is directly proportional to distance. d. kepler's laws can be deduced from newton's laws of motion and gravity.
