A situation is shown in which two objects A and B start their motion from same point in same direction. The graph of their velocities against time is drawn. u_A and u_B are the initial velocities of A and B respectively. T is the time at which their velocities become equal after start of motion. You cannot use the data of one question while solving another question of the same set. So all the questions are independent of each other. 7. After 10 s of the start of motion of both objects A and B, find the value of velocity of A if u_A = 6 ms^-1 , u_B = 12 ms^-1 and at T velocity of A is 8 ms^-1 and T = 4s

Means and standard deviations of the scores of an intelligence test of two classes of different sizes of 25 and 75 are M_(1) = 80 marks and M_(2) = 85 marks and SD_(1) = 15 marks and SD_(2) = 20 marks Calculate the combined mean and the standard deviation of the two classes.

Each question contains STATEMENTS-1 (Assertion) and STATEMENT -2 (Reason). Examine the statements carefully and mark the correct answer according to the instructions given below: STATEMENT-1: The life of radiactive object (organic origin) can found with the help of carbon dating. STATEMENT-2: _(6)^(14)C is a alpha and beta -emitter.
