Sound can travel through a medium, but it does not require a medium.

a. True.

b. False

What will not affect strength of a electromagnet?

Determine the kinetic energy of a 625-kg roller coaster car that is moving with a speed of 18.3 m/s

If you know the distance traveled by an object in 1 hour, then you can calculate a. its velocity. b. its displacement. c. its average speed. d. its instantaneous speed.

A 6.0 * 103 kg car accelerates from rest at the top of a driveway that is sloped at an angle of 19.3 ◦ with the horizontal. An average frictional force of 4.4*103 N impedes the car's motion so that the car's speed at the bottom of the driveway is 4.

An empty parallel plate capacitor is connected between the terminals of a 10.1-V battery and charges up. The capacitor is then disconnected from the battery, and the spacing between the capacitor plates is doubled.

An object is placed in a fluid and then released. Assume that the object either floats to the surface (settling so that the object is partly above and partly below the fluid surface) or sinks to the bottom.

Explain why it is important to have strong core muscles?

Potential energy is the energy an object has because of its A. density. B. size. C. location. D. speed. E. temperature.
