law student discussion

Identify the concept discussed. There are 5 teachers for every 20 students in a class. => proportion or rate or not enough information or ratio..

It is found experimentally that the current I flowing through a conductor is directly proportional to the potential difference V across its ends, provided the physical conditions (temperature, mechanical strain, etc.,) remain constant. That ..

The above discussion forms the basis of the second law of thermodynamics. This states that the entropy of the universe always increases in the course of every spontaneous (natural) change. Thus, combining the first and second laws of thermodynamics, the combined state..

A good illustration of the ideas discussed in this chapter is the motion of a cart pulled by a horse. Suppose the cart is at rest when the driver whips the horse. The horse pulls the cart and the cart accelerates forward. The question posed is as follows. The horse pulls the cart with a ..

Let us consider a student seated on a stool that can rotate freely about a vertical axis. The student, who is set into rotation at a modest initial angular speed wi, holds two dumbbells in an outstretched hand. His angular momentum lies along the vertical rotation axis, po..

Couple two spring balances A and B as shown in the figure. When we pull the balance B both the balances show the same reading indicating that both the action and reaction forces are equal and opposite. In this case, the pull of either of the two spring balances can be regarded as action and that o..

In many electrical circuits, Ohm's law cannot be applied. This happens when there is more than one source of emf in the circuit or when resistors are connected in a complicated manner. To solve such complex circuits, Gustav Robert Kirchhoff developed two laws based on charge neu..

Ohm's Law - It is found experimentally that the current I flowing through a conductor is directly proportional to the potential difference V across its ends, provided the physical conditions (temperature, mechanical strain, etc.,) remain constant. That ..

Need for Preservation - Plants and animals occupy diverse habitats. It becomes practically impossible for a biologist to study each and every plant or animal species in its natural habitat. Hence, over the years attempts have been made to preserve the plant species or animal species in a simulated ..

". We shall now go on discuss the motion of a body when it is being acted upon by a force. When two bodies, a heavy one and a light one, are acted upon by the same force for the same time, the light body builds up a higher velocity than the heavy one. But the momentum they gain is the sam..
