what is the wavelength of an electron that has a kinetic energy of 0.50 mev (relativistic)?

The wavelength of electron is

Explanation:

The kinetic energy of the electron is,

We need to find the wavelength of this electron. It can be calculated using the concept of DE-broglie wavelength as :

h is Plank's constant

m is the mass of electron

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

this means that the temperature of both substances will be equal

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
