Na becoz, you could vy=uy+gt where uy=0 but not sure if you can assume g=9.8. and then using that uy you can approximate the places with each time by ratios, but not sure how you would show that through calculation since no units given.
True. All I knew that you had to place the balls from both cannons on the same horizontal lines and that the ux is constant hence the horizontal distance at each second is constant and 3 seconds up hence 3 seconds down.
Also qv is the work done on moving across the electric field. So if it was not a stopping voltage it has nothing to no with kinetic energy besides providing it more after liberation.
Work function is a constant and has absolutely nothing to do with external field. It's the energy required to liberate. The only thing 0 sows that it was provided the exact work function on from light. I think it has something to do with. Gradient.
If u looked carefully it wasn't stopping voltage. But it rather was similar to a photocell voltage. The positive plate was on the other end of photoelectric plate
6 hrs if perfect. I usually used to get 5.5 hrs but wouldnt recommend 5.5. 7 would be more than enough. 6 is optimal- worked well for my brain to function.
Re: hmmm.
Cos I am screwed. I wanna rip my brain and fcking put it in your breakfast bowls and give you Neuron cereals. I fcking hate my brain. Even worse, I fcking hate myself for being a loser so I go and try not to feel like one and say ur wrong. Just take it as a joke when I say ur wrong.
