Explain about the piezoelectric effect.
Piezoelectric effect:
While crystals as quartz or tourmaline are stressed beside any pair of opposite faces, electric charges of opposite polarity are induced within the opposite faces perpendicular to the stress. It is termed as piezoelectric effect.
In X-ray tube, when high speed electrons strike the target, they move into the target. They lose their kinetic energy and come to rest inside the solid. The electron because of fin
Q. A coil of area of cross section 0.5 m 2 among 10 turns is in a plane perpendicular to a magnetic field of 0.2 wb / m 2 . Compute the flux through the coil.
meaning of pull
In nuclear fusion two or more than two lighter nuclei join to form a single heavy nucleus. The volume of one molecule so formed is less than the sum of the masses of parent nuclei.
One mole of H 2 at 300 K takes a volume of 10 lits in a cylinder fitted with a piston. It is expanded isothermally to 20 lits. Consider ideal behavior for the gas, determine W, Q,
