How long does it takes the sun to rotate the earth?

What assumption can be made about the densities of two different spheres that have an identical volume but very different masses?

If the initial velocity of the system were not zero, how would this affect your results?

Describe the properties of a longitudinal wave

Water is to be pumped to the top of a building that is 366 m high. If the density of water is 1.00 x 103 kg/m3, what amount of pressure is needed in the water line at the base of the building to raise the water to this height? a. 1.26 x 106 Pa c. 5.

Describe what happened as the ice melted. Where do you think the energy goes when it is not raising the temperature?

What are some examples of tools or objects that apply force?

You push a 45 kg wooden box across a wooden floor at a constant speed of 1.0 m/s. The coefficient of kinetic friction is 0.25. Now you double the force on the box. How long would it take for the velocity of the crate to double to 2.0 m/s

Why do you feel warm when you are standing away from a camp fire

A student in her physics lab measures the standing-wave modes of a tube. The lowest frequency that makes a resonance is 20 Hz. As the frequency is increased, the next resonance is at 60 Hz. What will be the next resonance after this? A. 80 Hz B.

For a satellite to stay in orbit around Earth, it has to be moving forward very fast all the time. What force will make it fall to Earth if it goes too slowly?
