so I just thought about how power (Watts) is Joules over a specific time interval... so if the Power is 1.60 x 1013Watts over a 2.50 ns interval, and P=J/Δt, then if I rearrange the equation to 1.60 x 1013 W * 2.50 x 10-9 s = Joules, i would also get the joules/second (aka Watts with a time...

So when I multiplied it, i got 40000J. When I divided instead, I got 6.4x10^21.

Homework Statement I have a question that involves comparing the energy output of a laser to the energy required to make tea. I've already calculated the energy to make tea and I know what to do to find how long it takes to make the tea but I'm struggling with the energy output part. It says...
