what did millikan conclude after performing his oil drop experiment

Aristotle, the great ancient philosopher performed some experiments to study the speed of freely falling objects. He observed that when two bodies of different masses were dropped simultaneously from the same height, the heavier object reached the Earth's surface earli..

To study the action of pepsin on proteins - Boil egg white in distilled water till a cloudy suspension is obtained. Cool it and divide the mixture into five equal portions in separate test-tubes. Label them A to E. Add different substances to each of the five tubes as shown in the table below and e..

Rutherford and his co-workers, performed series of scattering experiments and concluded that the entire mass and the positive charge is concentrated in a very small region at the centre of the atom, known as nucleus. The radius of the nucleus is about 10 - 1 5 ..

To find out about laws of magnetism you can perform the following simple experiment. Suspend a bar magnet as shown in figure, so that it can freely rotate. Allow it to come to rest. You will notice that it remains in north-south direction. Now bring N pole of second bar magnet n..

. When the card is flicked away with the finger the coin drops neatly into the bottle. For success in performing this trick the finger should move in horizontal plane so that the card is not tilted. Place a coin on a smooth card over a water glass. Give the edge of the card a sh..
