An hour of television consumes 1.45 x 10^-1 kWh. (kilowatt hour) of electricity. Each kilowatt hour use is equivalent to 3.6 x 10^6 joules of energy.
- Simplify the expression (1.45 x 10^-1) (3.6 x 10^6) to find how many joules a television uses in 1 hour
- Suppose you could release the resting energy in a raisin. About how many hours of television use could be powered by that energy?
