If a bar pendulum is suspended between the pole pieces of a magnet: Let us take another identical pendulum and kept in a field free region. If we oscillate both of them with the same force, it is observed that the one within the field damps faster. The 'bob' of the pendulum consists of a coppe..

Let us take the case of a heavy door. If a force is applied at a point, which is close to the hinges of the door, we may find it quite difficult to open or close the door. However, if the same force is applied at a point, which is at the maximum distance from hinges, we can easily close or open the..

1. Find the compounded ratio of a) 5:14 and 7:15 b) a+b:a-b; (a 2 -b 2 ):(a 2 +b 2 ) and a 2 +b 2 :(a+b) 2 . 2. In the ratio 7:8, if the consequent is 40, what is the antecedent? 3. Find a) reciprocal ratio of 3:5 b) duplicate ratio of 2:3 c) triplicate ratio of 3:4 d) sub duplica..

Oil rises through a wick due to capillarity. The narrow pores in the threads of a wick act like tiny capillaries, through which oil rises. Ink spreads on a blotting paper as the pores in the blotting paper act like tiny capillaries. Water rises to the tip of the plants through the tiny fibr..
