Shouldn't it be 0.2345(5) mm? And if I want to write, 666.66 nm +/- 71 nm, how can I represent the uncertainty in parenthesis? Thank you

Hello all, I used the micrometer in my lab that has a resolution of 100 nm. so, my measurement looks something like, 0.2345 mm, with an uncertainty of 0.00005 mm. But I don't want to write, (0.2345 +/- 0.00005)mm in my data table because it just looks a little awkward to have so many...

I tried to find a charge that when divided into each one of the measured charges gives a result within an error bar or two-three of an integer for each and every charge... but there was none in my 10 data sets and by the way, after getting those 100 values, how should I plot it? what would my...

but that value doesn't make too much sense to me since, drop 2 has less charge than drop 3, but has 45 charges... I have no idea why the author published such answers/methods on a textbook...

so i found this section from the website, (from grade 12 physics textbook surprisingly) They did a sample calculation for oil drop 1 and 2. and got 45/16=n2/n1 But when I use the method they described for oil drop 1 and 3 instead, I get 3.3750, which can be written as 3375/1000=27/8, which...

Can you maybe post the plot for me please? I don't quite understand the method (measured data - i times the smallest charge part...) And what does that plot represent? So do you think it's a bad idea to find n=6 ? Thank you :)

At this point I don't even understand why they wanted me to do this lab. They specifically asked for 10 measurements... If they really wanted me to find the magnitude of the fundamental charge, shouldn't they have asked for way more data sets? also, the first part of this lab asks if the...

yeah my smallest charge is 9.48661E-19, which is almost 6 times greater than the charge of an electron. I'm not sure if I should cheat a little bit, or just pretend like 9.48661E-19 is n=1. Since we already know that e=1.602*10^-19, I can just divide my smallest value (9.48661E-19) by e,and...

I understand that I should probably treat 4.347E-18 and 4.393E-18 as the charges that have same n, but that still doesn't quite answer my question. I need to find what the value for that n is in order to determine e- since q=ne. For instance, I think that 2.36235E-18 2.38032E-18 and 2.45932E-18...

I have 10 data sets for experimentally determined q values, 8.02757E-18 1.56403E-18 2.36235E-18 2.45932E-18 3.57009E-18 4.34722E-18 4.39376E-18 2.38032E-18 9.48661E-19 7.47934E-18 what would be the procedure to determine e?? Thank you!

I've got mg=kvf, when the e-field is zero, (taking downwards direction as positive), k is some constant and vf is the terminal velocity of an oil drop. Then when the e-field is on, mg+kve=Eq, where Eq is the force from the electric field, and k is the same constant and ve is the drift velocity...

Millikan oil drop hmm I guess I could use it either way then. I actually have another question at this point, it's about Millikan oil drop experiment. I've got mg=kvf, when the e-field is zero, (taking downwards direction as positive), k is some constant and vf is the terminal velocity...

Hello, If I have a measurement of 1cm, and have an absolute error of 0.1 cm, I know that I can write my measurement as (1±0.1)cm. If I want to write it with its relative error instead of an absolute error, can I still use the bracket? i.e) (1±10%)cm ? Thank you!

After finding the values, I'm asked to Plot a graph of P(v) versus v for the above region, connecting values of the probability density with a smooth curve. Also plot your uniformly-distributed x, y pairs. What fraction of these pairs fall under the curve?

Hello, i was given 100 x,y random numbers, and was asked to find: Using vmin = 0, 5 *vmax as bounds on the x-axis, and P(0) = 0, P(vmax) as bounds on the y-axis, generate a set of velocities vi where i = 1,...,n producing a set of random numbers from a distribution function. (When such a...
