An astronomical unit (au) is equal to the average distance from earth to the sun, about 92.9 × 10⁶ mi. a parsec (pc) is the distance at which a length of 1 au would subtend an angle of exactly 1 second of arc. a light-year (ly) is the distance that light, traveling through a vacuum with a speed of 186 000 mi/s, would cover in 1.0 year. express the earth – sun distance in (a) parsecs and (b) light- years.

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
