Question

Convert 1.00 kg to energy :

• A. $9.00\times {10}^{16}J$
• B. $3.00\times {10}^{8}J$
• C. $1.00\times {10}^{8}J$
• D. $6.00\times {10}^{16}J$

Answer 1

Answer: (A)

$9.00\times {10}^{16}J$

According to Einstein's mass-energy equivalence theory, $E=m{c}^2$

where $E$ is the energy, $m$ be the mass and $c$ be the velocity of light.

So, energy $E=\left(1kg\right)\times (3\times {10}^{8}m/s{)}^2=9\times {10}^{16}J$
