The radiation level measured on earth from a certain star is a sinusoidal function of time. at 2: 30 am today, the radiation was at its maximum, 22. the level then decreased to its minimum of 3 at 5: 30 am today. (a) determine the sinusoidal function that gives the radiation level t hours after mid- night last night. (b) starting from midnight last night, how long will it be until the level has been above 16 for a total of exactly 5 hours?

i don’t know what the answer is i wish i

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

no sign of dia of fuel cell

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.
