The particles that are usually in a much higher energy usually comes from the magnetic field of the Earth in which it is trapped consisting the Van Allen radiation belts. In addition to that, these radiation belts are somewhat essential because it protects satellites orbiting the Earth from the Sun's high energy radiation.
Different types of fronts produce different patterns of weather. When a cold, dense air mass pushes warmer air, it produces a cold front. A cold front can turn a heat wave into normal summer weather or turn cold winter air into very cold weather. Cold fronts often produce tall cumulonimbus clouds.
The lower case m =Apparent magnitude
The product of the voltage across a device- V and the charge (current) I passing through is electric power, represented with the letter P.
P=V*I.
The electric power is the rate of doing work
Voltage is measured in volts, current in amps and and electric power is measured in watts.
