When a ceiling fan is switched on it makes 10 rotation?

When a ceiling fan is switched on it makes 10 rotation?

Correct Answer: (c) 30 ∴ the required number of rotations = 40 – 10 = 30.

When a ceiling fan is switched off its angular velocity falls to half while it makes 36 rotation?

When a ceiling fan is switched off, its angular velocity reduces to half its initial value after it completes 36 rotations. The number of rotations it will make further before coming to rest is Assuming angular retardation to be uniform.

When a ceiling fan is switched off its angular velocity falls to half while?

When a celling fan is switched off, its angular velocity falls to half while it makes 36 rotations.

When a ceiling fan is switched off its angular velocity falls to half while it makes 36 rotations how many more rotations will it take before coming to rest?

Hence , proved that it will rotate 12 times more before it comes to rest .

When a ceiling fan is switched off its angular velocity reduces to?

When a ceiling fan is switched off, its angular velocity reduces to 50% while it makes 36 rotations.

When seen from below the blades of ceiling fan are seen to be revolving anticlockwise and their speed is decreasing?

Explanation: If the speed of the ceiling fan is decreasing then the direction of angular velocity will be in upward direction. But in counterclockwise direction, if the speed of the angular velocity increasing than the angular acceleration will be pointing in the downward direction.

When seen from below the blades of a ceiling fan are seen?

When seen from below , the blades of a ceiling fan are seen to be revolving anticlockwise and their speed is decreasing.

What is the relationship between radius and velocity?

The explanation relates to the fact that the linear distance traveled around the edge of the circle is also proportional to the radius. Over all, the greater the radius of the circle, for the same radial velocity, the greater the force.
