All the planets move around the Sun in a (i) Circular path (ii) Rectangular path (iii) Elongated path

Gravitational force is a conservative force. Since the work done by a conservative force over a closed path is zero, the work done by the gravitational force over every complete...

(ii) Revolution

(e) Let the breadth of rectangular plot = x metre therefor Length = 2x metre According to the question,  2x × x = 2592 or, x2 =2592/2 = 1296 therefor x = √1296 = 36 therefor Lenght of...

(b) Jupiter and Saturn are located between Mars and Uranus.

(b) A body moving with a uniform angular velocity ω on a circular path of radius r has radial acceleration equal ω2r directed towards the centre of the path.

(c) The radiation emitted by sun exerts a radial presssure on the comet. So the tail of comet is always directed away from the sun.

(b) Phloem layer of tissue just below the bark is responsible for carrying food from leave to roots.

Earth is a planet and here planets are called aeroplanes. So, earth will be called aeroplanes.
