discuss any four sources of determinate errors and proffer a solution for each sources

These errors always have the same sign. These can be eliminated by detecting the source of error and the rule governing this error. They are of 4 type..

We have studied that a triangle has six parts or six elements viz three sides and three angles. From geometry, we know that when any three elements are given of which necessarily a side is given, the triangle is completely determined i.e, remaining three elements can be determined..

Two Nicol prisms (got by combining two prisms of Iceland spar suitably cut) are placed between the source of monochromatic light, S, and the eye. Light passes through the first Nicol prism, P, the polarizer and gets plane polarized (vibrations are restricted to one plane only). This plane..

Electrolysis of copper sulphate solution It is found that copper is removed from the anode and is deposited on the cathode. Due to ionization, the CuSO 4 solution is dissociated. ..

Summary - Today most of our energy needs are supplied by the fossil fuels. In one hundred years coal will be the only one left as petroleum products may remain only for 3 to 4 decades. Little of stored energy will be left if we continue to use energy at the same rate. Fossil fuels are non..

Introduction - The plants upon which we depend for the food we eat, and for the oxygen we breathe, depend in turn upon the soil. A good soil supplies the plants with the mineral elements they use. Vigorous, highly productive plants can be grown in solutions of fertilizer minerals in the a..

Sl. No Nobel Gas Symbol 1. Helium He 2. Neon Ne 3. Argon Ar 4. Krypton Kr 5. Xenon Xe 6. Radon Rn The names of the elements had originated from different sources in different ways. Some of them are discussed here. For exampl..

. If the full-scale deflection of the galvanometer occurs for current I o and the ammeter is to have a range I m a x , we have The potentiometer is a device to compare potentials. Since the method involves a condition of no current flow, the device can be used to compare emfs of two sources..

Summary - If a current I flows through a potential drop V, the energy lost per second by the drifting charges is VI. In a resistor of resistance R, the loss of energy appears as heat. The rate of heat production P is P = VI = I 2 R = V 2 /R and is independent of the direction of current Electrolysi..

Calorific Value of Foods and Fuels - Nutritional value of foods, and the usefulness of fuels is determined by the heat (energy) they produce on heating. The energy released by the combustion of foods or fuels is usually compared in terms of their combustion energy per gram. It is known as..
