Acar traveled at a constant velocity of 70 mph from noon to 2: 00 pm. at 3: 00 pm the velocity of the car was 80 mph; and finally at 4: 30 pm the velocity of the car was 40 mph. calculate the acceleration of the car between 3: 00 and 4: 30 pm. a) -40 mi hr2 b)-26.67 mi hr2 c)26.67 mi hr2 d) 40 mi hr2

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
