Problem 1 (III): Calculate the volume of the cylinder shown below if the following dimensions are measured as:
d=(3.92±0.005)cm
and
h=(5.45±0.01)cm
Also, determine both the absolute and percent uncertainty of the calculated volume.

Problem 3 (II) How many nanoseconds are there in one “microcentury”?
Problem 4 (II) An angstrom (symbol Å) is a unit of length, defined as 〖10〗^(-10) m, which is on the order of the diameter of an atom. a) how many nanometers are in 1.0 angstrom? b) how many angstroms are in a centimeter? c) How far away is York from Kearney in angstroms (the distance is 79 miles and there are roughly 1.6 km in a mile).

- I have an homework where I was asked to get a generic 12 in/30 cm ruler and then answer the question in bold: Look at the smallest division and record what the uncertainty ▲x is of your tool. I am not sure how to ansswer this. Note: the previous question asked me to choose a unit of measurement on our tool which is the ruler and I choose inches (I hope that is a unit of measurement).arrow_forwardA measurement of the circumference of a disk has an uncertainty of 2.6mm.
