They are made in various designs to reduce friction. They reduce friction because rolling friction is smaller than sliding friction. These bearings are also lubricated to further improve their function. ..

An iron rod can be converted into a magnet by passing an electric current through an insulated coil wound around it. When the current flows, the iron bar gets magnetised. One end becomes North Pole and the other the South Pole. If the direction of the current is reversed, the No..

When a charged body is brought near the electroscope the light weight pith ball is first attracted to the rod. Once it has touched the rod it gets repelled. When the pith ball comes in contact with the rod some of the charge from the rod ..

Connect a charged plastic rod to an uncharged pith ball through a copper wire. Instantly the ball gets charge..

If one end of a metal rod is placed in a stove, the temperature of the other end increases gradually. Heat is transferred from one end of the rod to the other end. This transfer takes place due to molecular collisions and the process is ca..

In earlier days, doctors used stethoscopes consisting of thin wooden rods with broadened ends. By placing one end to his ear and placing the other end on the patient's chest, he could hear the sound of the heart beats transmitted through the wood. Motor mech..

It comprises of the nerve cells or the neurons. These nerve cells are bipolar. One end of the bipolar cells, synapses with the rods and cones and the other end synapses with the ganglions present in the next layer. There are certain nerve cells called the horizontal a..

Two Kinds of Electric Charges - You can electrify a glass rod by rubbing it with silk. Suspend such an electrified rod by a silk thread as shown in figure. If you bring another glass rod electrified in the same manner, you will notice that the rods repel each..
