Question

What’s the answer? And how do you solve it?

Answer 1

Answer:

D

By substitution,

418,400= 4.655 x $10^{-12}$ x $c^{2}$

Now we have to get the c^2 on the left side of the equal sign.

Then, combine the other terms (not the 10^ -12)

Other ways you could have done this:

Google the speed of light, and combine the terms in the answers to see which equals the speed of light. :)

Hope this helps! Brainliest plz!
