What are the particles produced in a cathode tube? a. hydrogen b. atoms c. x-rays d. protons e. electrons

Electrons

Explanation:

Cathode ray tubes were used as the technology behind the discovery of electrons. At first, electrons were called cathode rays.

Using the discharge tube, scientists discovered electrons and they were shown to have the following properties:

Electrons are therefore the particles produced in a cathode tube.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
