Question

If a wheel turns with constant angular speed then the angle through which the wheel turns in each second increases as time goes on the angle through which the wheel turns in each second decreases as time goes on each point on its rim moves with constant velocity the wheel turns through equal angles in equal times each point on its rim moves with constant acceleration If the angular velocity and the angular acceleration vectors of a rotating wheel point in opposite directions, then the wheel is slowing down the wheel is speeding up the wheel is starting to turn in the opposite direction the axis of rotation is changing direction None of these If the angular velocity vector omega of a spinning body points up out of the page, then, when viewed from above the page, the body is spinning about an axis that is parallel to the page counterclockwise about an axis that is normal to the page clockwise about an axis that is normal to the page about an axis whose length is changing about an axis whose direction is changing

Explanation / Answer

Here ,

1)

for the constant angular speed is

>> the wheel turns through equal angles in equal times

2)

if the angular acceleration is in oposite direction to that of angular velocity

as the angular velocity will decrease.

the wheel is slowing down

3)

Using Right hand rule

as the angular velocity is out of page

tha whel is spinning

clockwise about an axis that is normal to the page
