Inefficiency of the material or engine causes the output work of a machine to be less
than the input work. It is governed by the second law of thermodynamics wherein
no product of work can produce 100 percent efficiency. Only the Carnot engine
can produce a 100 percent effieciency.
The control variables of this experiment would be the distance from the top of the ramp to the bottom, the car, and the force of gravity on the car.
Answer:
Specific heat capacity is measured by determining how much heat energy is needed to raise one gram of a substance one degree Celsius. The specific heat capacity of water is 4.2 joules per gram per degree Celsius or 1 calorie per gram per degree Celsius
