Answer:
2 rad/s
Explanation:
For a rotating object, the linear velocity is given by
where 
is the angular velocity and 
is the radius.
The edge has a linear velocity of 10 m/s and the radius at the edge is 5 m.
A light wave that hits the surface of a pool gets refracted and gives us an apparent image of the surface of the pool, following the concepts of refraction.
<u>Explanation:</u>
Let’s recall the concept of refraction when a light wave passes from medium of rarer to denser. There is a change in the speed of light while travelling from medium of rarer to denser.
There can be a change in the direction as well. This property is known as “Refraction” and the best example to see refraction is watching the surface of a clean pond, lake or pool.
When the light travels from a rarer medium (air) to a denser medium (water), it changes its angle of direction and gets refracted and hit to our eye lenses. With this, we see the surface of the pool at a changed angle and it seems to be a bit shallow than its original depth.
The change in pressure measured across a given distance called a Pressure Gradient. The pressure gradient creates a net force that is directed from higher to lower pressure and is called the Pressure Gradient Force. ... As air increases in velocity, it is deflected by the Coriolis Force.

Determine the percentage error
First, we calculate the mean
This gives:
Next, calculate the mean absolute error (E)
This gives:
![|E| = \sqrt{\frac{1}{6}*[(1.54 - 1.51)^2 +(1.53- 1.51)^2 +.... +(1.45- 1.51)^2]}](https://tex.z-dn.net/?f=%7CE%7C%20%3D%20%5Csqrt%7B%5Cfrac%7B1%7D%7B6%7D%2A%5B%281.54%20-%201.51%29%5E2%20%2B%281.53-%201.51%29%5E2%20%2B....%20%2B%281.45-%201.51%29%5E2%5D%7D)
Next, calculate the relative error (R)
Lastly, the percentage error is calculated as:
