1) If we denote speed by S, distance by D and time by T, the relationship between these quantities is a) (a) S = DT b) (b) T = S/D c) (c) S = 1/T × D d) (d) S = T/D 2) Observe the figure given below: The time period of a simple pendulum is the time taken by it to travel from  a) (a) A to B and back to A b) (b) O to A, A to B and B to A c) (c) B to A, A to B and B to O d) (d) A to B 3) Nearly all the clocks make use of a) (a) straight line motion b) (b) periodic motion c) (c) random motion d) (d) circular motion 4) A simple pendulum takes 42 sec. to complete 20 oscillations. What is its time period? a) (a) 2.1 s b) (b) 4.2 s c) (c) 21 s d) (d) 8.40 s 5) Which of the following cannot be used for measurement of time? a) (a) A leaking tap b) (b) Simple pendulum c) (c) Shadow of an object during the day d) (d) Blinking of eyes 6) On which axis is dependent variable represented? a) (a) x-axis b) (b) y-axis c) (c) On any axis d) (d) Depends on the data 7) The correct symbol to represent the speed of an object is: a) (a) 5 m/s b) (b) 5 mp c) (c) 5 m/s-1 d) (d) 5 s/m
