two independent wheels start from rest and are given the same angular acceleration. the first wheel turns through (theta) radians before it reaches an angular velocity of (w) How many radians does the second wheel turn through before it reaches an agular speed of 13 (w)?

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
