A ship’s boiler steam comes out at 435 K and pushes through the system, exiting into the condenser, which is kept at 176 K by circulating seawater. What is the ideal efficiency of the ship’s boiler rounded to the nearest thousandth?

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

If forces acting on an object are unbalanced. true or false
