Blue light changes as it travels from diamond into crown glass at its speed increases.
Carbon cycle am pretty sure it that
Answer:
w'=(1/2)w
Explanation:
In order to calculate the angular velocity of the second wheel, you use the following formula:
(1)
v: speed of the wheel 1 = speed of the wheel 2
r: radius of the wheel 1
For the second wheel you have:
r'=2r
You replace this value of r' in the following equation:

The angular velocity of the second wheel is one half of the angular velocity of the first wheel
My average speed for a walk depends on how far I walk.
If I walk one mile or more, then my average speed is about 2 miles per hour.
