Black surfaces is you'r answer. or dark mater. ya those are you'r answer.
Answer:
i d k about that but I know it`s a Polish thing
Answer:
Work done,W= 250J
Displacement , s = 60
We know that, Work done = Force x displacement
i.e , W = Fxs
250 J = F x 60m
F = 250/60
=4.16 N
Hence , 4.16 N of Force is applied on the body.
Answer:
Explanation:
v = Speed of electron = 
(generally the order of magnitude is 6)
m = Mass of electron = 
Work done would be done by
The work required to stop the electron is
