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
Invention I think which is B as they don't invent things in an enquiry
The special feature of the upper mantle is the asthenosphere.It is located just below the lithosphere and is made up of rocks that is fluid and can move.The fluidity of these rocks powered the movement of the tectonic plates on the earths crust.Circular convection cycles in the hot,fluid upper mantle rock move the plates over the surface of the earth.
Answer:
It's displacement would be 25 km.
Explanation:
That is because you would subtract 10 from 35 to get the distance away from the starting point.
Some substances look alike and the density can help you determine which is which. It also helps to tell which is heavier than the other.
