7.11x 10⁶J
Explanation:
Given parameters:
Speed of light = 3 x 10⁸m/s
Mass of object = 23.7g = 0.0237kg
Unknown:
Energy = ?
Solution:
From Einstein's equation, we see that mass and energy are equivalent using the expression below:
E = mc²
Substituting the parameters:
E = 3 x 10⁸ x 0.0237 = 7.11x 10⁶J
