Almost all telescopes have a circular mirror. The area of a circle is proportional to
where
is the radius of the circle, the constant of proportionality being
Therefore the area of 150 meter telescope would be
times bigger than the area of the smaller (10 meter) telescope.
Answer:
Velocity
Explanation:
We finds that the winds are coming from the west at 15 miles per hour. This information shows the velocity of the wind. Since, velocity is a vector quantity. It has both magnitude and direction. 15 miles per hour shows the speed of wind and west shows the direction of wind motion.
Hence, the given information describes wind velocity.
The answer is wind forces and Earth’s rotation
When the mixture (the sugar and water) is frozen, it separates. The water molecules get closer together, separating and pushing the sugar crystals to the top.<span />
