1) write each of the following numbers in scientific notation and write the number of significant figures in each of them: 37.60 b. 0.0130 c. 13000 d. 1.2300 2 Perform the indicated operations to the correct number of significant figures using the rules for significant figures a. 37.60 x 1.23- b. 6.7/8.975- c. 3.765+1.2+37.21= 3) different measures of a length gave the following results in meters: 1.4717, 1.4753, 1.4719, 1.4711, 1.4759, 1.4723, 1.4722, 1.4756, 1.4705, 1.4715, 1.4749, 14719 use your calculator to find: a) average b) standard deviation: calculate the uncertainty of the mean: u (units: (units: (units: the known value for the length is 1.4715 m; find the percentage error between average and it: % error = Was the experiment accurate? YES NO Briefly explain your reasoning Was the experiment precise? YES NO Briefly explain your reasoningExplanation / Answer
By cheggs policy, I am supposed to answer only question 1, however I will ansewr question 2 as well.
1)Any trailing zeros occuring after decimal point is significant. In scientific notation, we keep only one digit before the decimal point
Hence,
a)3.760*10^1 (since 4 significant figures)
b)1.30*10^2 (since 3 significant figures)
c)1.3*10^4 (since 2 significant figures)
d)1.2300 (since 5 significant figures)
2)The answer will contain that many significant figures as the number of least in the question
a)37.60*1.23
least significant figure is in 1.23 = 3
so, 37.60*1.23 = 46.248
however, we will keep only 3 significant figures
so the answer is 46.2
b)6.7/8.975
s is the least number of significant figures.
so 6.7/8.975 = 0.7465
ROunding to 1 decimal place, the answer is 0.7
c)3.765+1.2+37.21
least significant figures is 2
so 3.765+1.2+37.21 = 42.175
but least is 2
so the answer is 42
