Communications satellites are used to bounce radio waves from the earth's surface to send messages around the curvature of the earth. In order to be available all the time, they must remain above the same point on the earth's surface and must move in a circle above the equator. How long must it take for a communications satellite to make one complete orbit around the earth? (Such an orbit is said to be geosynchronous.) Apply Newton's second law to the satellite and find its altitude above the earth's surface.
In a proton accelerator, the energy of proton is 20MeV, the diameter of the beam is 2.0mm, Find the current density and the particle density in the beam
A jogger runs 100m due east, then changes direction for the second leg of the run. At the end of the run, she is 350m away from the starting point at an angle of 25.0° north of east. What were the direction and length of her second displacement? Util..
Two horizontal forces, 218 N and 157 N, are exerted in opposite directions on a crate. What is the net horizontal force on the create? Be sure to indicate the direction of the net force. (Assume that the 218 N forces are in the positive direction.)
