By firing electrons from a cathode gun at a known velocity through an electric field of a known strength, J.J Thomson was able to observe how much the field deflected the beam. With a mass-to-charge ratio calculated, he could determine that the mass of the electron was not significantly heavy (in fact almost nothing compared to the proton or neutron)
Answer: rate of accelerations is same a=g
Explanation:
#3). The wavelengths of the four types of electromagnetic
radiation on that list line up like this:
Longest ... microwaves
next . . . . . infrared waves
next . . . . . visible light waves
shortest ... ultraviolet waves
#4). The word "visible" means "able to be seen". Infrared
light and ultraviolet light are not visible to human eyes.
