Impossible Moments ?? #shorts

It is impossible to construct a torch in the absence of

A. it is impossible to get a completely filled conduction band. B. It is impossible to get completely empty Valance band.

When A is an impossible event, then what is P(A)?

The magnetic dipole moment of a short magnetic dipole at a distant point along the equator of magnet has a magnitude of 'X' in SI u'nits. If the distance between the point and the magnet is halved then the magnitude of dipole moment will be .

An impossible set of four quantum number of an electron is

Statement -1 : Mutually exclusive events, none of which being an impossible event, are not independent. Statement-2 : Non impossible independent events are not mutually exclusive.

The dipole moment of a short bar magnet is 1.25 A-m^(2) . The magnetic field on its axis at a distance of 0.5 metre from the centre of the magnet is

Probability of a impossible event is …………

Four short dipoles each of dipole moment 'p' are placed at the vertices of a square of side a. The direction of the dipole moments are shown in the figure.

It is impossible for a reaction to take place if
