1. Electrons are accelerated in the picture tube of a television through a potential difference of 8.00 x 10ºV. (Use the values qe=1.60 x 10-19 C and
me=9.109 x 10-31 kg.)

a. What is the change in the potential energy of each electron traveling in
this tube?

b. What is the change in the kinetic energy of the electrons?

c. At what speed do the electrons hit the screen?

Ineed ! using proper grammar, spelling, and punctuation, write at least one 5 sentence paragraph describing 3 ways we use the elements of the electromagnetic spectrum (ems) in our everyday lives.

The force it would take to accelerate an 900-kg car at the rate of 6m/s2
