Another engine reaches its top speed in 7.5s. It is able to perform 250,000 J of wok in that time. How much power this engine have in that time?

33,333.3J/s

Explanation:

Energy expended which is the work done in Joule

=250,000J

Time taken to expend the energy =7.5s

Power =Unknown

Formula

Power =Work

Time

Hence, Power = 250,000J

7.5s

Power = 33,333.3J/s

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.
