chemical to thermal to electromagnetic
Explanation:
The best statement that shows the energy transformations that took place is from chemical to thermal to electromagnetic energy.
- In all isolated systems, energy is neither created nor destroyed but transformed from one form to another according to the law of conservation of energy.
- The firewood contains a chemical potential energy at rest. This energy is contained in the carbon chains of organic compounds it houses.
- When combustion takes place, kinetic energy in form of thermal energy is liberated. The bulk is in form of heat.
- This energy dissipates in all direction as a form of radiant electromagnetic energy in the infra-red range.

1. is heliocentric because it means that the sun is in the center of the solar system
2. Winter solstice- the day of the year with the shortest hours of daylight- December 21 or 22
Summer solstice- the day of the year with the longest daylight- June 21 or 22
Spring equinox- the equinox in spring- march 21 or 22
Fall equinox- the time when the sun crosses the plane of the earth's equator- September 21 or 22

In longitudinal waves, the particles of the medium or a system displaces back and forth(parallel) in the direction of the propagation of waves. In transverse waves, the particles of the medium or a system displaces perpendicular to the direction of the propagation of waves. Therefore, C is correct.

The amount of heat energy that must still be removed by the cooling system is 1300 kJ.
<h3>Conservation energy</h3>
The total energy before and after a transformation must be equal.
Based on this principle, the heat energy that must still be removed by the cooling system is calculated as follows;
Input heat energy = out put heat energy
E = h + w
2000 kJ = h + 700 kJ
1300 kJ = h
Thus, the amount of heat energy that must still be removed by the cooling system is 1300 kJ.
