If your center of mass is not over your base, what will happen?

Set the mass of person one at 10 kg and the mass of person two at 10 kg. The two people may be any distance apart. Note the force between them. This is the initial condition Mass 1 (kg) Mass 2 (kg) Distance (m) Force of Gravity (N)

Which portion of the electromagnetic spectrum is used in a microscope? a. infrared waves c. visible light b. gamma rays d. ultraviolet light?

What term is defined as the amount of charge stored per volt?

A plane is flying east at 135 m/s. The wind accelerates it at 2.18 m/s^2 directly northeast. After 18.0s, what is the magnitude of the displacement of the plane?

The same constant force, F, is applied to two blocks. The first block has a mass of M and the second block has a mass of 2M. Both blocks are initially at rest and the force acts on each of them for the same period of time, t.

Does the air in our atmosphere have mass?

Your instructor hands you a closed flask partly filled with room-temperature water. When you hold it, the heat transfer between your bare hands and the flask causes the water to boil. Quite impressive! How is this accomplished?
