In the calculation of the volume of a cube of nominal size, the uncertainty in the measurement of each side is 3.3%. The uncertainty in the measurement of the volume would be 20% 25% 30% 15% 10%

When nonmetric units we used in the United Kingdom, a unit of mass called the pound-mass (lbm) was used, where 1 lbm = 0.4539 kg. (a) If there is an uncertainty of 0.0001 kg in the pound-mass unit, what is its percent uncertainty? (b) Based on that percent uncertainty, what mass in pound-mass has an uncertainty of 1 kg when converted to kilograms?

Let A = 2 x2y3Where x= 16 ± 0.5 and y = 9 ± 0.3Please find the nominal value of A and the uncertainty in this term.

A function Fis given by / - 4 where y = (8.854 0.05) and x = (5.11 ÷ 0.03) What is the absolute uncertainty in F% Specifi vour answer up to three decimal places

I got 1.9mm for the diameter of the penny but I am having trouble understanding what zero offset is and also estimating uncertainty.

A car engine moves a piston with a circular crosssection of 7.500 ± 0.002 cm in diameter a distance of 3.250 ± 0.001 cm to compress the gas in the cylinder. (a) By what amount is the gas decreased in volume in cubic centimeters? (b) Find the uncertainty in this volume.

So we take a pile of paper, we count the number of sheets, and obtain 226. Then, we measure how tall the pile is with a ruler: 24.0 mm.   As discussed in section 1, we could have a long argument about how much exactly should the uncertainty of this measurement be. Let’s settle to ± 0.5 mm

A pyramid has a square base of side x and height h. The volume V of the pyramid is given by the expression: V - x²h 3 If V is measured to 5% and h is measured to 3%, what is the percentage uncertainty of ? Remember to include the % symbol with your answer.

What is the percent uncertainty in the area of a circle whose radius is 1.8 × 104 cm?

(a) How many significant figures are in the numbers 99.0 and 100.0? 99.0       100.0       (b) If the uncertainty in each number is 1, what is the percent uncertainty in each? (Give your answer to 3 significant figures.) 99.0       % 100.0       % (c) Which is a more meaningful way to express the accuracy of these two numbers, significant figures or percent uncertainties? significant figurespercent uncertainties
