Read each statement below carefully and state with reason and examples, if it is true or false. A cslar quantity is one that (a) is conserved in a proces (b) can never take negative values (c ) must be dimensionless (d) does not vary from one point to another in space (e ) has the same value for observers with differnt orientations of axes.

Text Solution

Verified by Experts

(a) False, because energy ( being a scalar quantity ) is not conserved during inelastic collisions.
(b) False, because the diensity ( being a scalar quantity ) has dimesions.
(c ) False, because the density (being a scalar a scalar quantity ) has dimensions.
(d) False, because gravitational potential ( being a scalar quantity ) vary from point to point in space.
(e) True, because the value of scalar does not change with orientation of axes.

Direction: Read the following information carefully and answer the questions that are given below. There are eight persons namely A, B, C, D, E, F, G and H sitting around a square table. Four persons are sitting on the corner of the square table and are facing inside, and four persons are sitting on the edge of the square table and are facing outside. No two consecutive alphabets are sitting next to each other, for example A is not sitting next to B, B is not sitting next to A and C and so on. B and D are sitting opposite to each other. H sits third to the left of C. A sits on one of the corners. B does not sit on the edge of the square table. A and H are to the immediate right of each other. H is not near to B. E and G are sitting opposite to each other. How many persons are sitting between D and F when counted from the left of D?
