Answers and Explanation:
Forms of Kinetic energy
- Translational kinetic energy
- Rotational kinetic energy
- Vibrational kinetic energy
Forms of Potential energy
- Gravitational potential energy
- Electrostatic potential energy
- chemical potential energy
Energy efficiency is a measure of the amount of energy conserved in a process. It is the ratio of the output energy to the input energy.
Differences between renewable and non renewable energy
- Renewable energy can replenish themselves by recycling and replacement while non-renewable energy cannot
- Renewable energy are continuously available while non renewable energy are exhausted
- Renewable energy has low carbon emission and hence environment friendly while non renewable energy has high carbon emission and not environmental friendly
Sources of renewable energy
Solar energy.
Wind energy.
Hydro energy.
Tidal energy.
Geothermal energy.
Biomass energy.
Sources of non-renewable energy
Coal
Petroleum
Natural gas
Distribution of energy consumption in the US by energy sector
Petroleum = 36.2 %
Natural gas = 28%
Coal = 13.9%
Renewable energy = 11.0%
Nuclear electric power = 8.4%
Most of the energy consumed by the United States is non-renewable
Electricity is a secondary source of energy. It is derived from the conversion of primary sources
A secondary source of energy is a derivative from the transformation of primary sources of energy

Explanation:
Please find attached the explanation to the answer given.
Answer:
2 is the numerical answer.
Explanation:
Hello there!
In this case, according to the given information and formula, it is possible for us to remember that equation for the calculation of the average kinetic energy of a gas is:
Whereas R is the universal gas constant, NA the Avogadro's number and T the temperature.
Which means that for the given ratio, we can obtain the value as follows:
