What is the direction of the rotational velocity vector of the jar lid when you open a jar of pickles? the rotational velocity vector is directed away from the jar. the rotational velocity vector is perpendicular to the jar's axis of symmetry. the rotational velocity vector spins around the jar. the rotational velocity vector is directed into the jar.

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.
