If a car used 260,000 w of power to complete a race in 15 s, how much work did the car do?

the answer is J. 3,900,000 got it right on the test

P = power used by the car = 260,000 Watt

t = time taken by the car to complete the race = 15 sec

W = work done by the car to complete the race = ?

Work done by the car is given as

W = P t

inserting the values given above

W = (260,000 Watt) (15 sec)

W = 3,900,000 Watt-sec

W = 3,900,000 Joules                              (Since Joules = Watt-sec)

W = 3.9 x 10⁶ Joules

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.
