(a) State the postulate of STR and deduce Lorentz Transformation.
OR
Give basic postulate of special theory of relativity. Derive Lorentz Transformation equations.
(b) Prove that particle having rest mass zero is always moving with velocity of light.
Resistance in Series: In such a combination the resistors give a single path to the passage of current and similar current passes by each of the resistors.
draw and explain the internal combustion engine as it relates to carnot cycle and otto cycle
Anode rays were discovered by: (1)Goldstein (b)J. Stoney (3)Rutherford (4)J.J. Thomson Ans: (1)Goldstein
Assume a 55.0-kg ice-skater, who was initially at rest, fires a 2.50-kg gun. The 0.045-kg bullet leaves the gun at a velocity of 565.0 m/s. What is the velocity of the ice-
For germanium the forbidden gap is (A) 0.15ev. (B) 0.25ev. (C) 0.5ev. (D) 0.7ev. Ans: For germanium the forbidden gap is 0.7ev.
How do you calculate tensile strength? Tensile strength isn't really measured; it's calculated. It is explained as the point at which a sample of material fails when subjected
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. Explain Snells Law? It is believed that Snell developed his well-known equation by purely empirical means. He made various measurements of the refracting properties of vario
Q. Define: current sensitivity of a galvanometer. The current sensitivity of a galvanometer is described as the deflection produced when unit current passes through the galvan
