Answer:
90MJ
Step-by-step 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
