Question

find the rest energy, in terajoules, of a 16.516.5 g piece of chocolate. 1 tj1 tj is equal to 1012 j1012 j .

Answer 1

1485 TJ

Step-by-step explanation:

Given that

m = (16.5*10^-3) kg

c = 3*10^8 m/s

E = mc^2

E = (16.5*10^-3 kg) * (3*10^8 m/s)^2

E = 1.485*10^15 J

To express in Terajoules

E = (1.485*10^15)/(1*10^12)

E = 1485 TJ
