40. a) The Astronomical Unit (AU) can be defined as the average distance between Earth and the Sun which is used to measure distances within our Solar System.

b) Light year is unit of length used in expressing astronomical distances and can be defined as "unit of astronomical distance which is equivalent to the distance of light travels in one year which is equal to9.4607 × 1012 km approximately

c) Astronomical unit is required in order to calculate massive distance of the universe

41. A Foucault pendulum, named after the renowned French physicist Léon Foucault, was designed as an experimental set up to demonstrate the rotation of the Earth. The action of Foucault pendulumis due to the Coriolis effect.

It is essentially a freely swinging pendulum of relatively large mass suspended by a long wire so that its perpendicular plane of swing is not confined to a particular direction. The suspended pendulumt swings in a constant direction that changes as earth rotates.
