Romi and Sony are two brothers. They wanted to go to the library. Just as they were leaving, father stopped Sony. So, Romi started alone. A little while later, Sony ran and
caught up with Romi. Then after going together for some time they reached the library,
where they sat down and read some books. All this is shown in the form of a graph. Look
at the graph and answer the following questions:
a. What was Romi’s speed per minute while he
was moving?
b. For how long did father keep Sony waiting?
c. How long did Sony run before he caught up
with Romi?
d. How far from home did Sony finally meet
Romi?

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.
