Explanation:
It doesn't depends upon other.
It have it's own identity.
It's a lot easier to measure temperature than to measure the motion of component particles.
Shale, sandstone, and limestone are the most commoc types of sedimentary rocks. They are formed by the most common mineral that is found on or near the surface of the Earth
Answer:
(A) It will take 22 sec to come in rest
(b) Work done for coming in rest will be 0.2131 J
Explanation:
We have given the player turntable initially rotating at speed of
Now speed is reduced by 75 %
So final speed
Time t = 5.5 sec
From first equation of motion we know that '
(a) Now final velocity
So time t to come in rest
(b) The work done in coming rest is given by
