Answer:

90MJ

Explanation:

Energy= mc^2

Where c= speed of light

m= mass of the object

Mass= m = 1 ug ( then we need to convert from micro gram to micro Joule)= 0.000000001

C= 3× 10^8 m/s

E= = [0.000000001 × (3× 10^8 )^2]

E = [0.000000001 × 89 875 517 873 681]

= 89 875 517.9 joule

Then we can convert to megajoules as

90MJ
