A25 v battery is connected into a circuit with two resistors in series. one resistor has resistance 5.0 o and the other has resistance 7.5 o. what is the voltage drop across the 7.5 o resistor?

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
