Explain the term ‘wave-particle duality' of matter.

A particle performing linear S.H.M, has maximum velocity of \(25 cm /\) s and maximum acceleration of \(100 cm / s ^2\). Find the amplitude and period of oscillation. \((\pi=3,142)\)

Draw a neat and labelled diagram of van de Graaf generator.

Draw a neat diagram for the rise of liquid in a capillary tube showing the components of a surface tension.

A bar magnet of mass \(120 g\) in the form of a rectangular parallelopiped, has dimensions \(l=40 mm\), \(b=10 mm\) and \(h=80 mm\), with its dimension ' \(h\) ' vertical, the magnet performs angular oscillations in the plane of the magnetic field with period \(\pi\) seconds. If the magnetic moment is \(3.4 Am ^2\), determine the influencing magnetic field.

Unpolarized light is passed through two polarizers. Under what condition is the intensity of the emergent light
(i) maximum
(ii) zero?

Explain why the inductance of two coils connected in parallel is less than the inductance of either coil.
