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 ba..

Simple Voltaic Cell - In order to study the working of an electrolytic cell and the phenomena of electrolysis it is important to know the working of a galvanic or a voltaic cell that generates electrical energy from its chemical reaction. In a simple voltaic cell a zin..

The angle between the direction of total intensity of Earth's field with the horizontal line in magnetic meridian. It is represented as d . At poles, the angle of dip = 90 o and at the equator, the angle of dip = 0 o . The dip at a place can be determined by an apparatus known as dipci..

J.J.Thomson proposed the first simple and most primitive model in 1898, which considered an atom to be a sphere of uniform positive charge into which the negatively charged electrons were embedded. This model was like a plum pudding dotted with raisins and was thus ca..

In a simple pendulum experiment, the data pertaining to period t in seconds of the pendulum and the length d in inches of the string are shown in the table. Choose the model and its equation which best fits the situation. Period (sec) : t Length(in) : d 0.4 1.81 0.8 7.24 1.2 16...

- Newton's Law of Gravitation and Einstein's Theory of Relativity were remarkable inventions in the world of Physics that changed the world. Physics is essentially a part and parcel of our everyday life and an understanding of its basic concepts is important to study advanced concepts like Electric..

Introduction - In the nineteenth century scientists saw enough evidence to prove that each element has its distinctive atom. But all tem atoms contain identical electrons. In spite of the fact that electrons carry negative charge, atoms as whole were found to be neutral. This led to the fact that a..
