Acold beverage can be kept cold even a warm day if it is slipped into a porous ceramic container that has been soaked in water. assume that energy lost to evaporation matches the net energy gained via the radiation exchange through the top and the side surfaces. the container and beverage have temperature t = 17°c, the environment has temperature tenv = 32°c, and the container is a cylinder with radius r = 2.52 cm and height 9 cm. approximately the emissivity as ε = 1, and neglect other energy exchanges. at what rate dm/dt is the container losing water mass?

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
