This doesn't prove it's a charged particle. Light has momentum too, it will propel a solar sail. Showing the beam has momentum does not prove that it is a charged particle.bucca.sam said:12 is a not b
Hertz incorrectly showed that the rays were not deflected by electric fields.
The paddle wheel experiment shows that the rays hold momentum, and therefore have mass - showing they are of particle nature.
They were shown to be deflected by electric fields later on when the technology of making vacuum tubes improved.
therefore 12 is A
In regard to question 4 I rearranged delta y=ut + 1/2at^2 to get t=sqrt(h/0.5a) then plugged in a few linear values for h and saw it wasn't increasing in a linear fashion.
