Answer:
E=6.75×10¹⁰J
Explanation:
Given data
Mass (m)=7.50×10⁻⁷kg
To find
Energy (E) = ?
Solution
From Albert Einstein’s theory of special relativity
E = mc²........eq(1)
Where
E is energy
m is mass
c is speed of light which 3.0×10⁸m/s
put values in eq(1) we get
E=(7.50×10⁻⁷kg)×( 3.0×10⁸m/s)²
E=6.75×10¹⁰J
