Assignment o A resistor dissipates 723 joules of energy in 3 minutes and 47 seconds. Calculate the rate at which energy is being transferred to this resistor in joules per second. What is its power dissipation in watts ?

O A 40-W night safety light burns for 9 hours.

a. Determine the energy used in joules.

b. Determine the energy used in watt hours. c. At $0.08/kWh, how much does it cost to run this light for 9 hours?

o For a certain device, 7-94%. If losses are 18 W, what are Pin and Pout?

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
