velocity of electromagnetic waves=3.0×10^8.
wavelength=velocity/frequency
(3.0×10^8)/(7.5×10^12)
=0.00004
Fusion is the energy source of stars. The energy that is being released from the gas collapse into a protostar causes the center of the protostar to become extremely hot. Once the core is hot enough, nuclear fusion commences. The fusion reaction is a very structured process, releasing a huge amount of energy.
Answer:
A
Explanation:
To measure wavelength, you would find the distance from crest (top of the wave) to crest.
Hope this helps! :)
The answer is "C" because the equator is closest to the sun, because the sun's rays hits the earth surface at the higher angel at the equator and also the sun is directly overhead the equator.
Heat, light, motion, sound can all be produced in a chemical reaction and could be considered forms of energy: thermal energy, electromagnetic energy, kinetic energy, and sound
