The following data sets are the length measurements of a raw material. The actual length of the part is supposed to be 3.2 mm. Which sets) do you prefer to the others? Briefly explain.HINT: Check the accuracy and the precision of each data set.Data Set 1: 2.91, 3.00, 3.50, 2.85, 3.22, 3.15, 3.49, 2.90, 3.27, 3.15Data Set I1: 3.13, 3.22, 3.19, 4.17, 3.21, 2.62, 3.25, 2.80, 2.40, 3.81Data Set I: 3.24. 3.18. 3.22. 3.20. 3.17, 3.23, 3.19, 3.20, 3.16, 3.24Data Set IV: 2.90. 3.00. 2.92. 2.95. 2.93. 2.97. 2.94. 2.99. 2.96, 3.00     Please donot provide solution in image format and it should be in step by step format and provide fast solution

(a) How many significant figures are in the numbers 999.0 and 1000.0? 999.01000.0 (b) If the uncertainty in each number is 10, what is the percent uncertainty in each? (Give your answer to 4 significant figures.) 999.0  %1000.0  % (c) Which is a more meaningful way to express the accuracy of these two numbers, significant figures or percent uncertainties?

I need the answer to three significant figures. That's what I'm having trouble figuring out

Bacteria and other prokaryotes are found deep underground, in water, and in the air. One micron (10-6 m) is a typical length scale associated with these microbes. (a) Estimate the total number of bacteria and other prokaryotes onthe Earth. (b) Estimate the total mass of all such microbes.

A study fonds that the metabolic rate of mamals is proportional to the mass of the mamal carried to the exponent of (3/4). By what factor does the metabolic rate of a 70.0 kg human exceed that of a 6.30 kg cat?\ 70.0 3/4 kg    = 6.09 6.303/4 kg I set up the values as a ratio and came up with 6.09. OK, I answered my own question. That is the correct answer.

1)A grocery store sells 5-lb bag of apples. A customer bought apples weekly and made a record of his purchases: The weighing scale in the grocery store has an uncertainty of 10.3 lb. The customer obtained the following measurements: Week 1: weight is 4.8 Ib Week 2: weight is 5.3 lb Week 3: weig is 4.9 Ib Week 4: weight is 5.4 lb What is the Percent Uncertainty of the bag's weight?

Still think that unit conversion isn't important? Here is a widely publicized, true story about how failing to convert units resulted in a huge loss. In 1998, the Mars Climate Orbiter probe crashed into the surface of Mars, instead of entering orbit. The resulting inguiry revealed that NASA navigators had been making minor course corrections in SI units, whereas the software written by the probe's makers implicitly used British units. In the United States, most scientists use Sl units, whereas most engineers use the British, or Imperial, system of units. (Interestingly, British units are not used in Britain.) For these two groups to be able to communicate to one another, unit conversions are necessary. The unit of force in the SI system is the newton (N), which is defined in terms of basic Sl units as 1 N=1 kg · m/s?. The unit of force in the British system is the pound (lb), which is defined in terms of the slug (British unit of mass), foot (ft), and second (s) as 1 lb =1 slug ·…
