A bar sits on top of a brown triangle with a black weight at the left end and a finger pushing on the bar at the right end. Dotted lines run above and parallel with the bar and vertically from the above dotted line to the center of the weight, the point where the triangle meets the bar, and the finger. The distance from the center of the weight to the point of the triangle is labeled 2 meters. The distance from the point of the triangle to the finger is labeled 5 meters. For the lever shown, a = 5 m and b = 2 m. What is the mechanical advantage of the lever? ill give 14 points if youll be my boo if your a girl

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 20c 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
