Question

20. (1) Does a more accurate of the two values have greater precision too? Explain with example.
(it) What is the order of magnitude of a quantity?​

Answer 1

Answer:

No, in this case, your measurement is not close to the known value. Precision refers to the closeness of two or more measurements to each other. For example:- if you weigh a given substance five times, and get 3.2 kg each time then your measurement is very precise. Precision is independent of accuracy

An order of magnitude is an exponential change of plus-or-minus 1 in the value of a quantity or unit. The term is generally used in conjunction with power-of-10 scientific notation. ... Thus, 23.15 is one order of magnitude smaller than 231.5, which in turn is one order of magnitude smaller than 2315.
