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
No;(Personal Note:Please Rate this and let me know if this helps) Reason: From the quantisation of charge charactersistic, we can say that charge comes in integral multiple of e (
Disadvantages of A.C. Transmission of power 1. An a.c. line needs more copper than a d.c. line. 2. The construction of an a.c. transmission line is more complex than d.c. tr

In nuclear fusion two or more than two lighter nuclei join to form a single heavy nucleus. The volume of one molecule so formed is less than the sum of the masses of parent nuclei.
sir, what are the apparatus required for the magnometer experiment and how to do it.TO finnd the magnetic materials. wsihing an speedy reply
molecular explanation of surface tension
For the arrangement shown in Figure find (a) the equivalent capacitance of the circuit, (b) the voltage across QR, and (c) the charge on each capacitor
Tesla; T (after N. Tesla, 1870-1943): The derived SI unit of magnetic flux density, described the magnetic flux density of magnetic flux of 1 Wb by an area of 1 m 2 ; thus it
