After the house in the sample problem has been seton the truck bed, the truck accelerates until it reaches a constant speed. If the force required to move the house horizontally a distance of 75.5 m is 3,150 N, how much has been done on the house

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
