The blades of a ceiling fan starting from rest reach an angular velocity of 22 rad/s in 50 s. Each of the four blades has a mass of 2.4 kg and a length of 0.67 m. what is the total moment of inertia?

what is the net torque working on the blades?​

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.
