Plzzz helppp A red ball is thrown straight down from the edge of a tall cliff with a speed of 30 m/s. At the same
time a green ball is thrown straight up with the same speed. If the green ball travels up, stops, and
then drops to the bottom of the cliff, how many seconds later than the red ball will it land?

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
