Figure shoes the distance -time graph of three person A,B and C.
(a)Which of the three travels the fastest?
(b)Are the three persons ever at the same point on the road?
©how far has c travelled when B passes A?
(d) how far has B travelled by the time it passes C?

Shows the position-time graphs of three cars A,B and C On the basis of the graphs answer the follwing questions: . a. Which car has the highest speed and which the lowest? b. Are the three cars evrs at the same point on the road? c. When C passes A , wher is B ? d. What is the time interval during car A travel between the time it passed cars B and C ?. e. What is the relative velocty of car B with respect to car C ?

You are given the position-time graph of three deffernt bodies A,B, and C , Find which will have grater velocity an which will have least velocity. .

Three persons A, B and C speak at a function along with 5 other persons. If the persons speak at random, find the probability that A speaks before B and B speaks before C

The displacement vs time graph for two waves A and B which travel along the same string arre shown in the figure. Their intensity ratio I_(A)|I_(B) is

The displacement vs time graph for two waves A and B which travel along the same string arre shown in the figure. Their intensity ratio I_(A)|I_(B) is

Draw a displacement-distance graph for two waves A and B such that the amplitude of wave A is three times that of wave B.

Fig. 2.42 given below shows a velocity-time graph for a car starting from rest. The graph has three parts AB, BC and CD. (i) State how is the distance travelled in any part determined from this graph. (ii) Compare the distance travelled in part BC with the distance travelled in part AB. (iii) Which part of graph shows motion with uniform (a) velocity (b) acceleration (c) retardation ? (iv) (a) Is the magnitude of acceleration higher or lower than that of retardation ? Give a reason. (b) Compare the magnitude of acceleration and retardation.

If A ,\ B and C are three matrices of the same order, then prove that A=B=>A+C=B+C .

The transversal displacement V_s time graph for two waves A and B which travel along the same string are shown in the figure. Their average intensity ratio I_A//I_B is

If A, B, and C are three square matrices of the same order, then AB=AC implies B=C . Then
