It shows deflection for the presence of current.However it can't be used for the A.C. current used at home.hope this helped.
To solve this problem , we will use the length contraction equation as follows:
L = L0((1 - v^2/c^2))^0.5
where:
L is the desired length
L0 is the length measured at initial frame = 1 m
v is the velocity
c is the speed of light
Substituting by these givens in the above equation, we can calculate L as follows:
L = 1((1 - (0.8 c)^2/c2))^0.5 = 0.6 meters
Answer:

-- You've GOT the kinetic energy of the bullet.
-- That's the amount of work that has to be done to stop it.
-- work = (avg force) x (penetration) and they just gave you the average force.
-- Did you think it would be this easy ?
