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
The earth's rotation about its axis changes measurably over time; You don't have to worry about the details; all you need to know is that our days are growing longer by about 2.3 m
a car has a mass of 34.01 kg. The race lasts 30 seconds. you think if the car attains an acceleration of .55 m/s^2 to attain a final velocity of 16.54m/s it will win the race. what

Q. What is electrostatic shielding? i) It is the method of isolating a certain region of space from external field. ii) It is basis on the fact that electric field inside a
Power factor improvement: The low power factor is because of the fact that most of the power loads are inductive and thus take lagging currents.
Explain internal or external forces Forces can be internal or external. For instance the mutual attraction of atoms within a block of wood are known as internal forces. Somethi
