multiplied by a power of 10 and must be between 1 and 10. Significant figures: The number of digits you quote when you write down the value of a quantity that has been measured with a degree of uncertainty. The smaller the number of significant figures quoted for a value‚ the smaller the uncertainty in that value. The significant figure is the number(s) that carry meaning to that particular range of digits. So in the figure 247300‚ the most significant number is 2 as it tells us the number is 2 thousand

It is supported in a horizontal position by two pivots‚ one situated at A and the other 2 m from B. A man whose mass is 80 kg is standing on the plank 2 m from A when his dog steps onto the plank at B. Given that the plank remains in equilibrium and that the magnitude of the forces exerted by each of the pivots on the plank are equal
