Inner radius is R and outer radius 3R, charge density is p, negatively charged, long cylinder. This cylinder is immersed in a dielectric constant k= 80 (clean water), then what is the electric field strength of the cylinder axes from distance 5R. Write E5R wtih R, p and ε0.

What is meant by the statement" the melting poin of glycerine is 13 degree celsius

Which configuration would produce an electric current? a) rotate a coil of copper wire between two magnets. b) connect a wire between a copper and zinc strip sitting in a beaker of water. c) connect a wire to the (+) positive end of a battery and the other end to a light bulb. d) connect a wire to the negative end of a battery and the other end to a light bulb.

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
