Suppose that you have two machines. Machine A gives 10 horsepower, and machine B gives 20 horsepower. You will use these machines to lift an object. Suppose that Machine A takes 1 kJ of energy to lift the object, and it does so in 1 minute. Select all of the statements below that are correct (there may be one or more)? (We assume machines are using their full horsepower, and there are no losses).
A. The object will take 1/2 kJ of energy for machine B to lift.
B. The object will take 1 kJ of energy for machine B to lift.
C. The object will take 2 kJ of energy for machine B to lift.
D. The object will be lifted in V2 minute by machine B.
E. The object will be lifted in 1 minute by machine B.
F The object will be lifted in 2 minutes by machine B.
G. None of the above statements are true.
