The number of significant figures in the measurement 210 cm is?
There are two significant figures in the measurement 210 cm.
How many significant figures are in 0.00301 cm?
There are four significant figures in 0.00301 cm. The non-zero digits (3 and 1) and zeros between them are all considered significant.
How many significant figure does 100.0 have?
It depends on how it is written. Strictly speaking, 10 has only one significant digit (1000 also has one significant digit). However, 10.00 has four significant digits. If you wanted to make the zero in 10 significant, a decimal needs to be placed after the zero; alternatively, a bar can be placed above the zero.ANS2:Since the ten did not come with units, it may be an exact count. If it is an exact count, it is infinitely precise. If you had exactly (see, you can't say "exactly" with a measurement) 10 rulers that were 10.00 cm long, the total length of all of them laid end-to-end would not be any more precise than the hundredths place. Your final answer would be 100.00 cm because in adding, you can have no greater precision than your least precise term. The least precise term is not the infinitely precise count. 10.00 cm + 10.00 cm + 10.00 cm + 10.00 cm + 10.00 cm + 10.00 cm + 10.00 cm + 10.00 cm + 10.00 cm + 10.00 cm = 100.00 cmThat is assuming you added. If you multiplied, you can have no more significant digits than the term with the fewest significant digits.10 x 10.00 cm = 100.0 cm.Not all counts are exact. "Ten, give or take one" would carry precision the same as 10 cm with no bar over the zero. It would be precise to the tens place.
How many cm are n 48 inch?
48 inches is 1,463.04 cm
How many significant figures are justified in a measurement of a length that is between 9 and 10 centimeters if the measuring device ruler has smallest divisions of 0.1 cm?
Two significant figures are justified in this measurement. Since the measuring device ruler has smallest divisions of 0.1 cm, the uncertainty lies in the last digit. The measurement falls between 9.0 cm and 10.0 cm, so the two digits, 9 and 0, are significant.
