When you apply a horizontal force of 50 N to a block, the block moves across the floor at a constant speed (μk = μs).
a. What happens if instead you apply a force of 41 N to the block initially at rest?
1. The block decelerates (the speed continually decreases).
2. The block doesn't move.
3. The block moves at a constant speed, but it moves more slowly.
b. When you apply a force of 41 N to the block initially at rest, what is the magnitude of the horizontal component of the force that the floor exerts on the block?
c. What happens if instead you exert a force of 53 N?
1. The block moves at a constant speed, but it moves faster.
2. The block doesn't move.
3. The block accelerates (the speed continually increases).
d. When you apply a force of 53 N, what is the magnitude of the horizontal component of the force that the floor exerts on the block?

4r-134a enters the condenser of a residential heat pump at 800 kpa and 50°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3°c. the refrigerant enters the compressor at 200 kpa superheated by 4°c determine (a) the isentropic efficiency of the compressor, (b) the rate of heat supplied to the heated room, and (c) the cop of the heat pump. also, determine (d) the cop and rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kpa.
