The answer is (B) Angular Velocity
\(\tau=\frac{d L}{d t}\)
If \(L\) is a constant, torque will be zero. which implies that no torque is applied. But our problem states that constant net torque which is not zero is applied.

6. A constant net torque is applied to a rotating object. Which of the following best describes the object's motion A) The object will rotate with increasing angular acceleration. B) The object will rotate with decr C) The object will have a decreasing moment of inertia D) The objeet will rotate with constant angular velocity E) The object will rotate with constant angular acceleration. easing angular acceleration.
When a net torque is applied to a rigid object it always produces a 1. constant acceleration 2. rotational equilibrium 3. constant angular velocity 4. constant angular momentum 5. change in angular velocity
Which of the following statements is false? The moment of inertia of an object depends on the location of its axis of rotation The moment of inertia of an object depends on the angular acceleration of the object as it rotates An object can continue to rotate in the absence of torque An applied net torque may reduce the angular speed of an object Of the particles that make up an object, the particle with the smallest mass may contribute...

orrect Question 1 0/2p When a net torque (non-zero) is applied to a rigid object, it always produces change in angular velocity constant angular velocity constant linear acceleration rotational equilibrium constant angular momentum correct Question 2 0/2 pts You are struggling to get a rusty bolt loose with a wrench. If you are maxed out on the force you can apply, what could you do/change to increase rotational motion of the bolt? Move your hand away from the bolt Move...
A counterclockwise torque is suddenly applied to a rotating shaft with a moment of inertia of 5 kg•m2 . The shaft was initially at rest (zero speed). If the applied torque causes the shaft to rotate at a constant angular acceleration of 1.5 rad/s2 , considering zero viscous damping: a) Calculate the applied torque. b) Calculate the angular speed of the shaft after 5 seconds in radians per second. c) Express the speed in revolutions per minute.
Describe a situation in which there is a net external torque on an object but it’s angular velocity both magnitude and direction is constant?
7. We construct a rotating object from four uniform rods (lying in the same plane), each of mass 1.2 kg and length 1.5 m joined at their ends to a central axle. The object is intially at rest: a net torque of 20.0 N m is applied to it for 5.0 s. a) What is the moment of inertia of the object? m 1.2 kg 1.5 m b) What is the angular acceleration of the object while the torque is...
The combination of an applied force and a constant frictional force produces a constant total torque of 35.7 N·m on a wheel rotating about a fixed axis. The applied force acts for 6.05 s. During this time the angular speed of the wheel increases from 0 to 9.8 rad/s. The applied force is then removed, and the wheel comes to rest in 60.2 s. (a) Find the moment of inertia of the wheel. kg·m2 (b) Find the magnitude of the...
