An object (candle flame) 2.5 cm high is 25.0 cm from a double convex lens. Where is the image of the candle flame, if the focal length of the lens is 18.4 cm? what is the magnification? Repeat the same problem just switching the convex lens to a concave lens.

Explain earth's motion, using the terms "precession" and "rotation" in your answer.

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
