Introduction
.02 cm. The unit of accuracy required is hundredth of a centimeter. Therefore, only digit 2 is significant. The 0 after decimal indicates the magnitude of measurement. Therefore, the 0 after decimal point is not significant. .02 cm has one significant figure...
Summary
We use specific number of digits to denote the value of a number to a certain degree of accuracy. For a number between 0 and 1, the successive zeros after the decimal are not significant. For a number with a decimal point, the final zeros ar..

. It causes an increase of the earth's temperature. Remember : If the temperature of the earth's atmosphere gradually rises it will result in melting of the polar ice, and cause the sea level to rise, which, in turn, will result in the flooding of all low lying areas, especially..
Weather Satellites
Scientists who investigate weather phenomenon are called meteorologists. To study a particular feature, may require an observation from a larger area. By combining great number of observations and analysing them by computers it is possible to get information about a large weather system. Satellites..
