A. The girl kicks a ball with a force of 10 N, what is the size of the reaction force? B. The baseball player hits the ball with a force of 20 N, what is the size of the reaction force?

C. The rockets thrusts push down with a force of 1,000 N, what is the size of the reaction force?

D. You blow a balloon up and let it go. Air pushes out to the left but the balloon moves to the right. Use Newton's Third Law to explain why this happens.

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
