How is torque related to force?

Torque is a measure of the force that can cause an object to rotate about an axis. Just as force is what causes an object to accelerate in linear kinematics, torque is what causes an object to acquire angular acceleration.

Fun Fact - Johnny Appleseed’s fruits weren’t for eating

Yes, there was a real John Chapman who planted thousands of apple trees on U.S. soil. But the apples on those trees were much more bitter than the ones you’d find in the supermarket today. “Johnny Appleseed” didn’t expect his fruits to be eaten whole, but rather made into hard apple cider.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
