The 3.7-kg slider is released from rest in position A and slides down the vertical-plane guide. If the maximum compression of the spring is observed to be 37 mm, determine the work Uf done by friction. The spring constant k

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
