Find the kinetic energy ofan electron that moves at half the speed of light to four significant digits.

Ke=electron kinetic energy=

Explanation:

The electron has a mass of

The speed of light in a vacuum is a universal constant with the value 299 792 458 m / s (186 282,397 miles / s), although it is usually close to

Kinetic energy (K) is the energy associated with bodies that are in motion, depends on the mass and speed of the body and is calculated using the formula:

       Equation(1)

K=kinetic energy (J)

m =mass of the body (kg)

v= speed of the body

for this problem We replace in the equation (1)

= electron mass

=Half the speed of light

=electron speed

We replace in  the  equation (1) :

The energy kinetic of the electron is

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
