All types of energy can be resumed into two basic types of energy which include kinetic energy and potential energy.
<h3>What is kinetic energy?</h3>
Energy is the ability to perform a given work. Kinetic energy is energy in movement, whereas potential energy is stored energy.
For example, plant photosynthesis makes reference to chemical energy (potential energy), popcorn makes reference to thermal energy, etc.
In conclusion, all types of energy can be resumed into two basic types of energy which include kinetic energy and potential energy.

Answer:
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
Explanation:
True, bc each element emits lights that have an unique wavelength and frequency
The last one should be right
Answer:
20.2 kJ
Explanation:
Based on the information in the reaction, the amount of heat released per mole of Na₂O₂ (the molar enthalpy) is calculated as follows:
126 kJ / 2 mol = 63 kJ/mol Na₂O₂
The number of moles in 25.0g of Na₂O₂ must be calculated using the molecular weight of Na₂O₂ (77.978 g/mol):
(25.0 g)/(77.978 g/mol) = 0.32060 mol Na₂O₂
Thus, the heat released will be:
(63 kJ/mol)(0.32060 mol) = 20.2 kJ
