The mathematical formula for gravitational force is F=GMmr2 F = G Mm r 2 where G is the gravitational constant.
Thermal energy
Uneven distribution of thermal energy
Water vapor in the atmosphere
The formula to find the speed of a wave
speed = wavelength x frequency
speed and frequency are directly proportional so as one increases then the other one will increase as well. in this case as the frequency increases then the speed of the wave will also increase.
hope this helps :)
An atom in normal conditions refers when electrons are in the fundamental state. When you leave the atom, an electron absorbs energy from an external source and moves to a higher energy state.
Energy states or energy levels are called orbitals. The difference between the energy states in an atom is responsible for the emission of photons when an electron transition occurs between these two energy states.
Because the energy levels are discrete, the emitted photons also possess different energies.
