Answer:
[tex]2.68\cdot 10^8 MJ[/tex]
Explanation:
The power is related to the energy by
[tex]P=\frac{E}{t}[/tex]
where
P is the power
E is the energy
t is the time elapsed
The power of this nuclear power planet is
[tex]P=3100 MW = 3.1\cdot 10^9 W[/tex]
The time we are considering is 1 day, which is
[tex]t = 1 d = 86400 s[/tex]
So we can re-arrange the previous equation to find the energy produced by the power plant in one day:
[tex]E=Pt =(3.1\cdot 10^9 W)(86400 s)=2.68\cdot 10^{14} J=2.68\cdot 10^8 MJ[/tex]
