Answer 1

i need a life fast plz

Answer 2

`m=0.002kg`

Explanation:

The given formula is:

`E=mc^2`

Divide both sides by
`c^2`.

`\implies (E)/(c^2)=(mc^2)/(c^2)`

Cancel out the common factors to get;

`\implies (E)/(c^2)=m`

`m=(E)/(c^2)`

When
`E=1.8*10^(14)J` and
`c=300,000,000ms^(-1)`, then

`m=(1.8*10^(14))/(300,000,000^2)`

This simplifies to

`m=0.002kg`
