problems involving measurements

Different types of lengths are measured by using different types of instruments. Lengths like the length of cloth or length of a line can be measured by using measuring tape, a metre scale or a foot rul..

The mass of a gas can be measured by direct weighing. The container in which the gas is enclosed is first weighed. Then the weight of the container, after removing all the gas, is measured again. The difference between the two weights gives the mass of the ga..

To measure an angle we shall use two kinds of units, the degree unit and the radian un..

When we make use of various measuring instruments, we encounter various types of errors. They ar..

Measurement of Length - Different types of lengths are measured by using different types of instruments. Lengths like the length of cloth or length of a line can be measured by using measuring tape, a metre scale or a foot rule. But these instruments cannot b..

A voltmeter is a device used to measure 'potential difference' and an ammeter is a device used to measure 'current'. Ammeters are connected 'in series' to the components through which the current to be measured flows. Voltmeters are connected in parallel to the compon..

Temperature is a measure of hotness or coldness of a body. It is a measure of kinetic energy possessed by the molecules. A hot body is said to be at a higher temperature and a cold body is said to be at a lower temperature. The devices used to measure temperature are ..

No measurement is ever perfectly accurate. Even with high precision instruments some error is inevitable. There are two main types of error..

It is the mass of a body measured, when it is in translatory motion, by the application of external force other than gravit..
