A turntable spins on frictionless axle with an unchanging speed. Does any part of the turntable exert a torque on any other part.of the turntable? No, since the various parts of the turntable do no on each other, they cannot exert torques on each No, since the entire object has the same angular i tarques are exerted by one part of the turntable o Yes, these internal torques are what must be coun object's inertia in order for it to keep spinning. Yes, but since these internal torques cancel out.in of each part of the turntable stays the some IDONT KNOWYET

Yes, but since these internal torques cancel out, the speed of each part of the turntable stays the same.
Explicación
## Step 1The problem is about the concept of torque and its application in a spinning turntable. Torque is a measure of the force that can cause an object to rotate about an axis. It is calculated by multiplying the force applied by the distance from the axis of rotation.## Step 2In the case of a spinning turntable, each part of the turntable is exerting a force on its neighboring part. This force is due to the friction between the parts of the turntable.## Step 3However, the torque exerted by each part on its neighboring part is equal and opposite. This is because the force is applied in the opposite direction to the torque.## Step 4Therefore, the total torque on the turntable is zero. This is because the sum of the torques exerted by each part on its neighboring part is zero.## Step 5This means that the turntable is in a state of rotational equilibrium. In other words, the turntable is spinning at a constant speed.
