Speed is distance over time, learn that formula and look at the image
Temperature doesn't do anything, the boiling point of stuff decreases. If you put water in a vacuum chainber then it will start to boil
Answer:
Explanation:
Time taken to complete one revolution is called time period.
So, Time period, T = 1 s
Diameter = 1.6 mm
radius, r = 0.8 mm
Let the angular speed is ω.
The relation between angular velocity and the time period is
![\omega =\frac{2\pi}{T}](https://tex.z-dn.net/?f=%5Comega%20%3D%5Cfrac%7B2%5Cpi%7D%7BT%7D)
ω = 2 x 3.14 = 6.28 rad/s
The relation between the linear velocity and the angular velocity is
v = r x ω
v = 0.8 x 10^-3 x 6.28
v = 0.005 m/s
Because when you spill water on it, the reflection comes from the surface of the water, not the ground glass.
