Three resistors are in parallel. The current in the first resistor is 0.1 A The power in the second resistor is 3 watts. The voltage across the third resistor is 100 volts. Find the resistance of the three
resistors and the total resistance if the total current is 0.2 A.

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
