How many significant figures are contained in each of the following measurements?(a) 53 $\mathrm{cm}$(b) $2.05 \times 10^{8} \mathrm{m}$(c) $86,002 \mathrm{J}$(d) $9.740 \times 10^{4} \mathrm{m} / \mathrm{s}$(e) 10.0613 $\mathrm{m}^{3}$(f) 0.17 $\mathrm{g} / \mathrm{mL}$(g) 0.88400 $\mathrm{s}$

a) The decimal point position is understood that it is placed after the two non-zero digits.b) The zero between two non-zero figures.c) The decimal point position is understood that it is placed after the two non-zero digits.d) Zero to the right of the decimal point after non-zero number is significante) Zeros between the non-zero numbers are called captive zeros and are significant.f) The leading zero to the left of the decimal point has no value and is insignificant. The non-zero numbers to the right of the decimal should be counted.g) Trailing zeros after the non-zero digits are considered significant while leading zero to the left of the decimal is not significant.

how everyone says Ricky. And today, working on problem 49 on, we're gonna be determining the number of significant vigorous that air contained in each of the following measurements. All right, so 53 centimeters, I'd be too sick. Thinks right. Six big, um, 2.5 times sent to the eighth. Be 36 things. Who's that? Um, a 6000 and two jewels. That is one do 3456 figs, 9.740 time. Sense of the fourth meters per second, but forcing things 10.613 That is 66 figs. Wait 17 grams room with milliliters to six weeks. Last but not least 0.88400 seconds has 566 And, um, these trailing zeros can have some pretty
