1.4 x 1035 J
3.5 1018 J
3.7×1017 J

Answer 1

D

Step-by-step explanation:

Answer 2

The energy equivalent of an object with a mass of 4.1 kg is 3.7 ×
`10^(17)` J.

Step-by-step explanation:

One of the significant findings of Einstein is the mass energy equivalence. According to this law, the energy is equivalent to the product of mass and square of velocity of light.

Thus, the equation became E = m
`c^(2)`

As here ,the mass is given as 4.1 kg and c is known as 3×
`10^(8)` m/s, then the energy equivalence of this object will be

E = 4.1 × 3 × 3 ×
`10^(16)` J = 4.1 × 9 ×
`10^(16)`J = 36.9×
`10^(16)` J= 3.7 ×
`10^(17)` J.

Thus, the energy equivalence of object with mass of 4.1 kg is 3.7 ×
`10^(`17)` J.
