Can you explain uncetiany and sig figues to me. Why would 30 with +- 0.1 uncertainity have have two sig figs. My question is how does uncertian relate to the number of sig figs.

ANSWER QUICK! Ive read the honor code and it says that their a question can have up to 3 subparts (i.e. part a, b, and c). So please answer all questions. Frodo is walking fast towards Mount Doom. What is the minimum uncertainty in his position, given that his velocity is 1000 2.0 mm.s-1? Frodo has a mass of 50 kg. (1 mm = 10-3 m). Pick correct answer: a)5.3 x 10-34 m, b)5.3 x 10-31 m , c)5.3 x 10-38 m, d)1.3 x 10-34 m, e)1.3 x 10-23 m 2. In the H atom, which of the following transitions will result from the absorption of the highest frequency photon? Select all that apply (Assume all transitions are possible). Pick correct answer: a)4d to 1s, b)2p to 4d, c) 3s to 6f, d)2p to 3s, e) 4p to 1s, f) 2p to 4s 3.Which of the following quantum numbers can be used to describe a 5p orbital? (Select all choices that apply) a)n=5; l = 1; ml = -1, b)n=5; l = 0; ml = -1, c)n=5; l = 1; ml = 0, d)n=5; l = 2; ml = -1, e)n=5; l = 0; ml = 1

HELP ME ASAP 1. The universe has a typical temperature of only 3.0 K. If the intensities of light of different frequencies follow a blackbody distribution, then which frequency of light does the universe give off most? 2. A new, extremely precise apparatus has measured momentum (y component) of a certain proton to be: 5 x 10-28 kg m/s with an uncertainty of only 2 x 10-29 kg m/s. If the y-position of the proton is also measured, approximately what is the lowest possible uncertainty with which this measurement can be made? 3. What electrical force does a Uranium nucleus (Z=92) exert on one of its inner electrons, located at a distance of 175 picometers (=1.75 x 10-10m) ?
Describe the scope (where it has been proven consistent) and limits (where it fails to explainobservations) of the standard model.
I need help with this physics question, please. If you can't answer it, can you explain what the question is asking, please? Below is the question: Consider the errors involved in the measurements you made in this lab in both length and mass. Search the internet to find devices that exceed the precision of devices used in this lab. Can you find the maximum experimental precision of mass and length measurement that has currently been achieved?

How can errors, if not eliminated, be minimized? Identify the type and the suggested ways. Which measurement for lengths has a greater absolute uncertainty? (estimated uncertainty). Which measurement for lengths has a greater relative uncertainty? (percent uncertainty). Why are there differences between the relative uncertainties of measurements? How can uncertainties, if not eliminated, be minimized? Suggest ways.
Then, why the answers are different when I use different formulas, dB= 10log (I/ I0) and I= I0 10^-ax? The first one is 5e-5 W/cm^2 and the second one is 5e-23 W/cm^2.
