When point charges q = +8.4 uc and q2 = +5.6 uc are brought near each other, each experiences a repulsive force of magnitude 0.66 n. determine the distance between the charges. ns

Which notation is used to represent an alpha particle? a. b. c. d.

What is special about a dc circuit ?

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
