The zeroth law of thermodynamics describes the state where we can say what about the movement of heat between two substances?

How does Einstein's famous equation, E = mc2, relate to the production of the Sun's energy? Be sure to include what each factor in the equation represents with respect to what happens inside the Sun.

A woman walks 237 m in the direction 27.2 east of north, then 335 m directly east. Find the difference between the distance the woman walks and the magnitude of her displacement. (Answer in m.)

If you were going to invent a new way to power your mobile phone, which type of electromagnetic wave would be most useful to investigate? A. Radio waves, because they are high energy and common. B. Gamma rays, because they are strong and safe. C.

Compare the Lagrangian method with the Newton-Euler method in detail.

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.
