It takes about 8 minutes for light to travel from the sun to earth. pluto is 40 times as far from us as the sun when pluto is closest to earth. how long does it take light to reach earth from pluto? (b) radio waves travel at the speed of light. what problems would you have if you tried to conduct a two-way conversation between earth and a spacecraft orbiting pluto?

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
