In simple harmonic motion, the magnitude of the acceleration is greatest when the:
1. displacement is zero
2. displacement is maximum
3. none of these
4. velocity is maximum
5. force is zero

Distinguish between a transverse wave and a longitudinal wave.

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 ∘c is 31.8 torr.
