Question

prove that cathode rays have mass and kinetic energy...​

Answer 1

Answer:

hi

good afternoon sorry but I didn't understood your questions

Answer 2

Answer:

Cathode rays are elecgtrons emmitted from a heated wire and accelerated by an electric field. The have a mass m and a speed v, there vor they have a momentum m*v and an energy m*v²/2.

In early times and still today a prperty defined as one term multiplied with another was called momentum, therefore we have a torque momentum M = force * length of the lever, or a statistical momentum of first and secand order = means and standard deviation. The momentum asked for hear is aka impulse - a better chaice for descriptiion.
