C. Useful energy out of a system is always less than the energy input of that system.
Explanation:
The correct statement of the given options is that useful energy out of a system is always less than the energy input of that system.
This is in compliance with the third law of thermodynamics which states that "energy transformation in a system is not 100% efficient".
- At every stage energy is usually lost when it is transformed from one form to another.
- There is no machine that is 100% efficient.
- A machine that is 100% efficient will convert all the useful energy in it to do work and even more.
- In system energy is usually lost as a result of heat and to overcome friction.
- This reduces the amount of energy out of a system.

Answer:
Encyclopædia Britannica, Inc. The forearm and the lower leg have two long bones each. In the forearm are the radius—on the thumb side of the forearm—and the ulna; in the lower leg are the tibia (the shinbone) and the fibula. The radius corresponds to the tibia and the ulna to the fibula.
Explanation:
(Initial individuals + newborn individuals) - dead individuals = total individuals
Growth rate = (total individuals/initial individuals) * 100
Population growth rate = new percentage minus 100%
Calculations
(1000 + 500) - 200 = 1500 - 200 = 1300
Growth rate = (1300/ 1000) * 100
= 1.3 * 100
= 130%
Population growth rate = 130% - 100%
= 30% per year if it is uniform
