Answer the following questions:
Is the permeability of a ferromagnetic material independent of the magnetic field? If not, is it more for lower or higher fields?

Predict the polarity of the capacitor in the situation described below:

Suppose we define a quantity 'Linear Pomentum' as linear pomentum = mass × speed. The linear pomentum of a system of particles is the sum of linear pomenta of the individual particles. Can we state a principle of conservation of linear pomentum as ''linear pomentum of a system remains constant if no external force acts on it?''

At a place, the horizontal component of earth's magnetic field is B and angle of dip is 60°. What is the value of horizontal component of the earth's magnetic field at equator?

Two wave pulses identical in shape but inverted with respect to each other are produced at the two ends of a stretched string. At an instant when the pulses reach the middle, the string becomes completely straight. What happens to the energy of the two pulses?

Write any one equation representing nuclear fusion reaction.

Two thin lenses of power + 6 D and – 2 D are in contact. What is the focal length of the combination?

Two circular loops are placed with their centres separated by a fixed distance. How would you orient the loops to have:

1. The largest mutual inductance.
2. The smallest mutual inductance?

A point charge q is placed in a cavity in a metal block. If a charge Q is brought outside the metal, will the charge q feel an electric force?
