Refrigerator
Unplug the refrigerator, remove the fuse and look at it. Typically the fuse will be dark in color, much the same as a blown light bulb.
372.48 nano joule
810 joules / 30 minutes = 810 joules / 1,800 seconds = 0.45 joule per second = 0.45 watt.By the way:-- The battery supplies the energy at the rate of 0.45 watt.-- The radio uses or consumes the energy at the rate of 0.45 watt.
Work is force x distance = 700 x 4 = 2800 Joules
56 kilo joules = 56,000 joules
A petajoule is 1015 joules (Quadrillion joules)
36.72 joules.

There are 704 calories in 704 calories. If you intended to ask about joules, then 704 calories is about 2,947.51 joules.
A calorie is about 4.2 joules, therefore a kilocalorie is about 4200 joules. You can multiply by this number.
480 calories = 2,009.664 joules.
80 calories is about 335 joules.
102 joules is 24.362281 calories.
