Answer:
Explanation:
The rest energy of any substance is defined by the Einstein's mass energy equivalence relation. Thus the rest mass of a electron is 9.11x10^-31 kg. The speed of light is 299,792,458 m/s. Thus multiplying the square of speed of light with the rest mass of electron gives the rest energy of the electron.

Explanation:
They would feel warmer cause black attracts heat and also could attract bees
Explanation:
hope you understood fella
Answer:

Explanation:
We have,
Speed of an electron is 
It is required to find the De Broglie wavelength of electron. The formula for the De- Broglie wavelength is given by :

h is Planck's constant
m is mass of an electron
Plugging all the values we get :

So, the De-Broglie wavelength of an electron is
