Answer:
E(final)/E(initial)=2
Explanation:
Applying the law of gauss to two parallel plates with charge density equal σ:
So, if the charge is doubled the Electric field is doubled too
E(final)/E(initial)=2
The non-relativistic formula for low speed v < 0.1c is:
K.E = 0.5mv^2 = 0.5 * 235 * (7)^2 = 5757.5 J
The design of rutherfords experiment show what he was trying to find out is by detect charged particles. He shot positively charged alpha particles at foil containing gold atoms, what they did showed what was in them neutrons etc Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
Answer:
The refraction of light at the surface of water makes ponds and swimming pools appear shallower than they really are.
Explanation:
so its just the refraction of light at the surface
distance(d) = speed(s) × time (t)
= 22.3 × 8.5
= 189.55m
