Two heavy objects of masses 1 kg and 2 kg are moving towards each other under the mutual gravitational force of attraction between them. At a particular instant,
distance between them is 1 m. Find the acceleration of the object of mass 2 kg in terms
of the gravitational constant G.

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

Explain the comparisons between nature and packingtown that appears on pages 81 and 82 answer

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell
