What angle we take between magnetic field and plane of loop....discuss the cases when induced emf is zero in a rotating frame.Ans) We know that Magnetic Flux through a given area is given as ?=B.A= BAcosθLet θ=wt, where w is frequency of sourceNow, the Induced emf will be zero if:1. Magnetic field B is zero,2. Area of the conductor is zero.3. Angle between Magnetic field and Area Vector is 90oAlso the angle between the Magnetic field and plane of loop is taken as anticlockwise angle or positive angle
Why is quantum mechanics important? Quantum mechanics is important to understand the behavior of systems at atomic length scales and duration smaller. For illustration, when Ne
INELASTIC COLLISION: "The collision in which total momentum is preserved but total K.E of system is not conserved is known as inelastic collision". It is to be noted that m
The simple equation E = mc² is not usually applicable to all these types of mass and energy, except in the special case that the total additive momentum is zero for the system unde
