An electron with a speed of 0.939 is emitted by a supernova, where is the speed of light. what is the magnitude of the momentum of this electron?

Explanation:

It is given that,

Speed of electron, v = 0.939 c

c is the speed of light

Mass of electron,

The momentum of this electron is given by the product of mass and velocity. It is given that,

p = m v

So, the momentum of the electron is . Hence, this is the required solution.
