A 1.6kg block of ice is being pulled to the left with a force of 14N at an angle of 30º above the horizontal. Assume that friction is negligible (that it is so small you can ignore it). What is the normal force? What is the acceleration of the block?

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.
