Max ang. speed(u) = 18 rad/s
final ang. speed(v) = 0
ang. displacement(s) = 220 rad
ang. acceleration = (v^2 - u^2)/2s = -18^2 / 2*220 = -0.7364 rad/s^2
v = u +at
0 = 18 - 0.7364t
t = 18/0.7364
t = 24.44 seconds
<h2>
Answer:The angle between the refracted ray and the normal.</h2>
Explanation:
Refraction is defined as the phenomenon of bending or changing course of a light ray when it passes from one medium to another medium.
The new ray formed after the bending at the surface of new medium is called the refracted ray.
The angle between the refracted ray and the normal of the point on the surface of the new medium where the ray enters is called angle of refraction.
Refer the attachment for instance.
In short,it is the angle between the refracted ray and the normal.

<h2>Natural Resource:</h2>
- The resources, for example, sunshine, air, water, soil, plants, animals, minerals, rivers etc. which after natural formation remain distributed on the earth, are known as natural resource.
- The natural resources are found in solid, liquid or gaseous states, and in metallic or non metallic form.

Hope it help you </h2>
A jumble of relatively young volcanic debris, some of it located where it fell in Mount Hood’s eruptive past, some of it moved here by the colossal advance of the Newton Clark Glacier during the last ice age.
Newton Clark Moraine
As a result, the rocks making up the moraine are sharp and raw, not rounded, and the debris is largely unsorted. Giant boulders perch precariously atop loose rubble, making the moraine one of the most unstable places on the mountain.
Answer:

Explanation:
THE GIVEN sheet can be taken as two horizontal force with surface charge density is
at one surface is ∈_1 = 
at oher surface is ∈_2= 
the magnitude of electric field due to surface charge is given as
So, electric field at P (2 CM below from surface is) = E_1 +E_2
