Answer:
30643 J
Explanation:
= Vacuum permeability =
t = Time taken = 1 ns
c = Speed of light =
= Maximum electric field strength =
A = Area =
Magnitude of magnetic field is given by
Intensity is given by
Power, intensity and time have the relation
The energy it delivers is 30643 J
True because friction happens when two things are rubbed against each other and it creates force and sliding something vigorously against something else can create force.
M=2.45 because you multiply out the equation on the right and divide by 10
