- observe the angles ABP and ABQ Now, in D le PAB, we know that values of and AB. \ AP can be determined. In D le QAB, we know the values of and AB. \ AQ can be determined. In D le PAQ, we know the values of AP, AQ and \ PQ can be determine..

The figure below shows the displacement-time graph of a moving particle. Consider any two points A and B on the graph. The coordinates of the points A and B are {x (t 1 ), (t 1 )} and {x (t 2 ), (t 2 )} respectively. Therefore, we conclude that the slope of the straight ..

Total Internal Reflection Consider an object at O in a denser medium. A ray of light incident normally to XY goes undeviated along AB. As the angle of incidence increases, the angle of refraction also increases. On increasing the angle of incidence for a particular value say i = C, the angle of ..

The electrodes used in the cells discussed so far, deteriorate with the passage of current and cannot offer a constant emf indefinitely. However, there was a few cells called standard cells, which can maintain a fairly constant emf over very long periods of time compared to the other cells. The com..

Electrodes: Copper vessel (+ve) Zinc rod (-ve) (amalgamated) Electrolyte: dil. H 2 SO 4 Depolarizer: CuSO 4 solution The porous pot (of fired clay or porcelain) allows ions to pass between the two solutions, but prevents the solutions from mixing. A perforated shelf containing CuSO 4 crystal..

This is a portable form of Leclanche Cell. A moist paste of NH 4 Cl and ZnCl 2 is contained in a zinc vessel acting as the negative electrode. ZnCl 2 is added to the electrolyte NH 4 Cl. It keeps the paste moist because it is highly hygroscopic. The top is sealed with shellac or pitch so that paste..

Consider the positions, where Then y = 0 R = 0 Since y = 0, these positions correspond to nodes. The strain represented by will be maximum at these points. ..

The ordinary magnetic effects in materials are determined by atomic magnetism. On continuing to cut a magnet into its smallest bit, we reach the level of a single atom. This is a tiny current loop in which the current corresponds to the circulation of the electrons in the atom. To this atomic curr..

The following results can be deduced from velocity-time graph. The acceleration produced in a body The distance covered by a moving object We can derive the equations of motion Let us see how to calculate the distance covered by a moving object from speed-time graph. The figure below gi..
