What is the energy equivalent of an object with a mass of 25 kg?
55% 10
75% 102
38% 1015
225 + 10

Explanation:

The energy equivalent of the mass of an object can be calculated by using the Einstein's equation:

where

E is the energy

m is the rest mass of the object

is the speed of light

For this object

m = 25 kg

So its equivalent energy is:

coil wire, increase current, put iron inside the coil

a, c, d, e are all applying about success strategies.
