Problem 71

A thin stream of water is pulled to a rubber balloon witha static electric charge. Might a small ice cube also bepulled to a statically charged balloon?

Step-by-Step Solution:
Step 1 of 3

All of the rotational motion equations are essentially the linear motion equations but with angular quantities. I.e use theta in place of x, angular velocity in place of v, alpha in place of a An object will change directions if ang. acceleration (rad/s^2) and angular velocity (rad/s) For a rotating disk w/ constant ang velocity, tangential acceleration = 0, radial acceleration cannot be 0 Tan acceleration = r * ang. Acceleration Rad acceleration = ang velocity^2 * r Pulley problems: Angular velocity is larger for smaller radius if 2 pulleys move with same ang velocity Moment of inertia depends on m and r^2. Needs to be calculated by axis For pulleys: rad acceleration is larger for larger disc if 2 move at same ang velocity Torque is the angular equivalent of force (torque =
