Answer:
8 meter telescope 16 times more gather light than 2 meter telescope.
Explanation:
The amount of light gather by the telescope is known as Light Gathering Power (LGP).
Light Gathering Power is determine by the relation:
In this problem, let l₁ and l₂ be the length of two telescopes and (LGP)₁ and (LGP)₂ be the light gathering power of two telescopes respectively. Then the ratio of their LGP is :
Substitute 8 m for l₁ and 2 m for l₂ in the above equation.
Answer:
Because of more rainfall.......
Explanation:
They receive more rainfall than low lying areas because the temperature on top of mountains is lower than the temperature at sea level. Winds carry moist air over the land. ... As the air rises, it cools, and because cool air can carry less moisture than warm air, there is usually precipitation (rain).
Regardless of the speed at which the two police cars were passed, the really important thing is the average speed between the two points. The distance traveled between these two points (x) is 39miles and the time between them is:
The speed limit is 70mph
Average speed is the change at the distance in this time, then
That means the average speed is less than the speed limit. The police cannot do anything against the average speed that was done during the two points.
