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.

The figure above shows distance-time graphs of two objects X and Y. Which object is mov ing with greater speed? (1) Both objects are at rest (2) Both objects are moving with same speed (3) Object Y (4) Object X

Pick the false statement (1) One can calculate uniform acceleration (2) One can calculate non uniform acceleration from velocity-time graph. (3) One can calculate velocity from distance-time graph. (4) One can calculate speed from distance-time graph.

The relation among v, w and r is - (1) w = v / r (2) v = w / r (3) w = r / v (4) None of these
