GALLIUM PHOSPIDE: It has band gap of 2.3ev. it can be used for light emitting diodes which can emit green or red light. The red light is obtained with zinc or cadmium oxide doping.
SELENIUM: It is found in crystalline and non-crystalline form. It is used as rectifier material for photo voltaic cells and for xerographic printing. Selenium films are used as photo electric light meters. Its melting point is 2200C.
LEAD: it is soft heavy and bluish gray metal. It is highly resistant to many chemical actions but can corrode by nitric acid, lime and rotten organic substances. Lead and its compounds are toxic. It is mechanically weak it cannot withstand vibrations at high temperatures. It alloys easily with Tin and zinc and forms many commercial alloys, including solders and bearing metals.
#questia 17KG cat is shot out of a hole in the side of a charged plate when the voltage is suddenly turned up to 5000V. The cat has a charge of 2.377^16c. He lands in a 3kg crate o
Formers used for winding coils are ceramic or glass, because they are stable. Copper wire with silver plating is used up to 50 M Hz. Lit wire produces lower RF resistance than soli

Earth's atmosphere is separated into four layers: The troposphere (0-10 km), the stratosphere (10-50 km), the mesosphere (50-80 km), and the thermosphere (80-500 km).
A section through a magnetic circuit of uniform cross-sectional area 2cm 2 is shown in fi gure. The cast steel core has a mean length of 25cm. The air gap is 1mm w
Two Cars in 2-Dimensional Collision Inelastic Collision : Collisions among objects are governed through laws of momentum and energy. While a collision occurs within an isola
The number of independent directions in which a system (or gas molecule) can have motion, are called as the number of degrees of freedom of that molecule or object. The number of d
An x-ray photon collides with a free electron, and the photon is scattered. During this collision there is conservation of: a) momentum but not energy b) neither moment
Internal Resistance of Circuit: As mentioned earlier in the section on batteries, every source of electricity, such as a cell or generator has resistance to current flow called
BCS theory (J. Bardeen, L.N. Cooper, J.R. Schrieffer; 1957) A theory put forth to describe superconductivity and superfluidity both. This recommend that in the superconducting
