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.
Q. Illustrate the Newton s laws of motion? Answer:- 1. A body at rest will stay at rest and one in motion will remain in motion until and unless acted upon by an external

A charge q1 is 9.00um is at the origin, and a charge q2 is -4.00um is on the x- axis 0.30m from the origin. find the electric field strength at point P, which is on the y - axis 0.
a) Two long wires, carrying currents i 1 and i 2 , are placed perpendicular to each other in such a way that they just avoid to contact. Determine the magnetic force on a small le
A small air bubble is inside a cube of 0.21 m. When viewed from one face it seems to be at a depth of 0.06 m, when viewed from opposite face the bubble seems to be at a depth of 0.
Superfluidity: The phenomena through which, at sufficiently low temperatures, a fluid can flow along zero viscosity. Its causes are related with superconductivity.
There is strong evidence that some short-duration gamma-ray bursts occur in systems with no star formation and where no massive stars are present, such as elliptical galaxies and g
Q. What would occur if a disk one light second in circumference were to spin at 60 RPM? Answer:- 60 revolutions for each minute is one revolution per second. 1 light se
Resistors in dc circuits: Components are said to be in series when they are connected end-to-end providing only one path for the current. Thus the same current passes through
