There are two bags, one of which contains 3 black and 4 white balls while the other contains 4 black and 3 white balls. A die is thrown. If it shows up 1 or 3, a ball is taken from the 1^(st) bag, but it shows up any other number, a ball is chosen from the 2^(nd) bag. Find the probability of choosing a black ball.

Two thin lenses of focal lengths f1 and f2, are in contact and coaxial. The power of combination is

Two point objects are placed on principal axis of a thin converging lens. One is 20cm from the lens and other is on the other side of lens at a distance of 40 cm from the lens. The images of both objects coincide. The magnitude of focal length of lens is :-

Two identical conducting rods are first connected independently to two vessels, one containing water at 100^@C and the other containing ice at 0^@C . In the second case, the rods are joined end to end and connected to the same vessels. Let q_1 and q_2 gram per second be the rate of melting of ice in the two cases respectively. The ratio q_1/q_2 is (a) 1/2 (b) 2/1 (c) 4/1 (d) 1/4

Two coaxial solenoids are made by winding thin insulated wire over a pipe of cross-section area A = 10cm^2 and length l = 20 cm. If one of the solenoids has 300 turns and the other 400 turns, their mutual inductance is ....... [mu_0=4pixx10^(-7) "TmA"^(-1)]
