10) At work a heavy 50kg box is pushed towards the corner of the room. If you apply 98N of force and the box in contact with the ground has a coefficient of friction equal to 0.2, how fast would the box accelerate? 1.8 m/s/s
0 m/s/s
2 m/s/s
0.04 m/s/s

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?

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

Arefrigerator uses r-134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. the refrigerant enters the evaporator at 120 kpa with a quality of 34 percent and leaves the compressor at 70°c. if the compressor consumes 450 w of power, determine (a) the mass flow rate of the refrigerant, (b) the condenser pressure, and (c) the cop of the refrigerator. (0.00644 kg/s, 800 kpa, 2.03)
