Two objects, A and B, are brought into contact with each other. The initial temperature of object B is 430 K. The heat capacity of object A is a constant 3 J/K and the heat capacity of object B is a constant 2 J/K. Through the exchange of heat the two objects eventually obtain a common final temperature of 340 K.

1. The initial temperature of object A was K.
2. The amount of heat exchanged during the process of obtaining the final temperature was J.
3. The final temperature would be (higher, lower, stay the same), if the heat capacity of object B was higher and the other given parameters remain constant .

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
