Question

What is the energy equivalent of an object with a mass of 2.5 kg?

Answer 1

This is the answer on Edgenuity 2.25*10^17

Answer 2

Answer : Energy equivalent of an object with a mass of 2.5 kg is $E=2.25\times 10^{17}\ J$.

Explanation :

It is given that mass of an object is, m = 2.5 kg

It is required to find energy equivalence.

According to mass energy equivalence relation :

$E=mc^2$

Where,

m is the mas of an object.

c is the speed of light $c=3\times 10^8\ m/s$

$E=2.5\ kg\times (3\times 10^8)^2\ m/s$

$E=22.5\times 10^{16}\ J$

$E=2.25\times 10^{17}\ J$

Hence, this is the required solution.
