While you are asleep, your body needs to get rid of about 64 J of waste heat every second. The body does this by transferring the heat from the interior of your body (temperature 37°C) to the skin (temperature 30°C), where it is radiated away. By how much does this heat transfer change the body's entropy each second?

What is the most useful equation for electric power?

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
