Cathode rays were shown to be a stream of "electrons".
Cathode rays (likewise called an electron beam) are streams of electrons saw in vacuum tubes. In the event that a cleared glass tube is outfitted with two anodes and a voltage is connected, the glass inverse the negative terminal is seen to sparkle from electrons radiated from the cathode. Electrons were first found as the constituents of cathode beams. The picture in an exemplary TV is made by centered light emission redirected by electric or magnetic fields in cathode ray tubes (CRTs).
Answer:
0.37 m
Explanation:
Given :
Window height, 
= 1.27 m
The flowerpot falls 0.84 m off the window height, i.e.
= (1.27 x 0.84 ) m in a time span of 
seconds.
Assuming that the speed of the pot just above the window is v then,
![$v=\left(\frac{30}{8}\right) \left[ (1.27 \times 0.84) - \left( \frac{1}{2} \times 9.81 \times \left( \frac{8}{30 \right)^2 \right) \right]}$](https://tex.z-dn.net/?f=%24v%3D%5Cleft%28%5Cfrac%7B30%7D%7B8%7D%5Cright%29%20%5Cleft%5B%20%281.27%20%5Ctimes%200.84%29%20-%20%5Cleft%28%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%209.81%20%5Ctimes%20%5Cleft%28%20%5Cfrac%7B8%7D%7B30%20%5Cright%29%5E2%20%5Cright%29%20%5Cright%5D%7D%24)
m/s
Initially the pot was dropped from rest. So, u = 0.
If it has fallen from a height of h above the window then,
h = 0.37 m
