## anonymous 4 years ago Electricity goes about \$0.05 Kilowatt hr, in form of electricity how many joules can you get for a dollar?

• This Question is Closed
1. TuringTest

a joule is a watt times a second, so we have$1\times\frac{10^3W\text{hr}}{0.05}\times\frac{3600s}{\text{hr}}$will give us watt-seconds=joules

2. anonymous

So my answer is 7.2 x 10^7 J is that right?

3. TuringTest

seems that way

Thanks!
