The correct velocity-time graph for zero acceleration is: (1) Graph-D (2) Graph-A (3) Graph-C (4) Graph-B

40 A body starts falling from height &#39;h&#39; and travels distance h/2 during the last second of motion. The time of travel (in sec.) is- (1) √ 2 -1 (2) 2 + √2 (3) √2+ √3 (4) √3 +2

What is true about scalar quantities ? (1) Scalars quantities have direction also. (2) Scalars can be added arithmetically. (3) There are special laws for scalar addition. (4) Scalars have special method to represent.

In case of a moving body- (1) Displacement &gt; Distance (2) Displacement &lt; Distance (3) Displacement ³ Distance (4) Displacement £ Distance

Which of the following is not characteristic of displacement ? (1) It is always positive. (2) It has both magnitude and direction. (3) It can be zero. (4) Its magnitude is less than or equal to the actual path length of the object.
