Question

A nuclear reaction releases 9.00 × 10^13 J of energy. What was the change in mass?

5.0 × 10^-4 kg

1.0 × 10^-3 kg

5.0 × 10^-3 kg

5.0 × 10^-2 kg

Answer 1

Here it comes!

\(E = m \ c^2\)

\(\Delta m = \frac{ E}{c^2}\)

Answer 2

so E is 9.00 × 10^13, what is c?

Answer 3

oh nvm is 3.0 x 10^8

Answer 4

so .001 = 1.0 × 10^-3?

Answer 5

looks good
