If the net torque on a rotating object is zero, the angular velocity of the object cannot change. True or False? Explain
A. True , Explan: _________
B False , Explan: _________
(I know the answer is B, I need help on explanation) Thanks
Ans :- False
Explanation:- If the net torque acting on a body is zero, then the body is said to be in rotational equilibrium. In
such a case, the angular velocity of the body remains constant.

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.
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...
1) An object rotating at 500 rpm (rev/min) is spinning faster than an object rotating at 500 rad/s. True False 2) If you're goin to calculate an object's tangenital velocity from its angular velocity, the angular velocity can be expressed in either rad/s or rev/min True false 3) Tangential acceleration is measured in m/s^2 true false
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

The torque τ required to rotate a disk of diameter D with angular velocity w in a fluid is a function of the density ρ and the viscosity μ of the fluid (torque has units of work) (a) Find a nondimensional relationship between these quantities. (b) Calculate the angular velocity and the torque required to drive a 750 mm diameter disc rotating in air if it requires a torque of 1.2 Nm to rotate a similar disc of 230 mm...
1. In order to change the angular momentum of an object, it is necessary to apply O a a net force to the object. O b. a net torque to the object. O c. a centripetal acceleration to the object. O d, both a net force and a net torque to the object. 2. We have three vectors, labeled A, B, and C. A points due west, B points due north, and C points due east. We don't know their...
