Explain the term- Zener Breakdown
Under a very high reverse voltage, depletion region expands and potential barrier increases resulting in a very high electric field (3X107 V/m) across the junction. Electric field would break some of the covalent bonds of semiconductor reverse current. This is known as Zener effect. Breakdown occurs at a particular and constant value of reverse voltage known as the breakdown voltage.
As an electron passes close to the positive nucleus of atom, the electron is moved from its path as given in diagram. This results in deceleration of the electron. The loss in powe

At what temperature would the average speed of helium atoms equal (a)the escape speed from Earth, 1.12 ´ 10 4 m/s, and (b) the escape speed from the Moon, 2.37´ 10 3 m/s? (See Ch
TIME OF FLIGHT: "It is the total time for which the projectile remains in air". As, the body goes up and comes back to similar level, so it does not cover vertical distance,
