A satellite of mass =238 kg is in circular orbit around the Earth at an altitude above the earth's surface equal to the earth's mean radius (6370 km). At this distance, the free-fall acceleration is /4.What are (a) the speed and (b) the magnitude of the centripetal acceleration of the satellite?

Diamond will scratch quartz. true or false

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
