Answer:
it will take
to reach its final rotating speed
Explanation:
Let initially the turntable is at rest
So its initial angular velocity will be 
Let the turn table is rotating with an angular acceleration 
According to first equation of motion
We know that
, here
So 
So it will take
to reach its final rotating speed
A horseshoe magnet has north and south, so does a bar magnet, but with the horseshoe magnet, the whole thing is bent so both ends are the same way. <span />
Answer:
1/6 m/s^2 ( about 1/6th gravity of Earth ( 9.81 m/s^2)
Explanation:
Displacement = yo + vo t - 1/2 a t^2
- 3.2 = 0 + 0 - 1/2 a(2.0)^2
- 3.2 = -2a
a = 3.2 / 2 = 1.6 m/s^2
