The accuracy of a measuring instrument depends upon the least count of the measuring instrument. For example, length of a body that can be measured using a tailor's tape, cannot be beyond the minimum and maximum length of the measuring tape. Least count of this tape is the least distance that can ..

It is the shortest distance between two ends of the body. For measuring lengths, two methods can be employed, namely direct method and indirect method. Direct methods are employed for measuring small lengths by comparing such lengths or distances with an approved standard of length viz. vernie..

Let us consider the following entries in a Students' Journal: (a) Weight of a calorimeter = 42 g (measuring instrument used is spring balance) The smallest reading the spring balance can record is 1g. There are 42 of 1 g units of measurement. Hence, there are two significant figures in the result. ..

> (c) up to 4 significant figures - 8.578 Example 3: Suppose you are measuring the diameter of a cylinder using a vernier calliper as 2.38 cm. The accurate value may lie between 2.375 cm and 2.385 cm. In this case figures 2 and 3 are absolutely correct while 8 is reasonably corr..

. The plotted points must be joined with a single straight line or a continuous curve. The graph should cover as much of the area of the graph paper as possible. This requires a sensible choice of scale for each axis. It is unlikely that points plotted from real experimental results will all lie on..
