Experiment analysis Definition and 24 Threads

I understand what happens in experiment, but my understanding of pressures isn’t the perfect. Torricelli used a one meter long glass tube with opening on one end with mercury inside it. He then dipped the tube into a bowl of mercury and mercury started to dip from tube. However it stopped after...

The SEW Experiment, named after its authors, Marian 0. Scully, Berthold-Georg Englert &Herbert Walther, was published in 1991 under the title, "Quantum optical tests of complementarity," and can be found here: https://www.nature.com/articles/351111a0.pdf They built atom interferometers with...

I'm using two tanks of nitrogen and oxygen and mixing them in different ratios to change the oxygen partial pressure in the system. System is opened to the atmosphere through the venting pipe which therefore sets the total pressure of the system to 1 bar. System is opened and gases flow through...

TL;DR Summary: School project about induced drag - I do not have a wind tunnel - and a comparison between rectengular straight wing, C-wing, and box wing (not airfoils) I want to know how to derive/ seperate induced drag from the parasite drag So, I am making an experiment where I'm supposed...

Hi, First of all, sorry if this is not the right place to post my question I was not sure where exactly to post this kind of question. I'm wondering how can I find the value of a constant experimentally. For instance, I have a equation ##l = AB^{4/3}##, with a set of data for ##I## and ##B##...

I've conducted this experiment yesterday. The main goal of this experiment is to find a gas constant R and compare it with its theoretical counterpart but I get stuck in calculating a Cv so I tried to find out what's wrong with my calculations by trying to calculate a Cv from the given data...

I did an electrolysis experiment with 1.6M Barium Chloride solution and the electrolyte turned black after the electrolysis. I am fairly positive that Chlorine was produced at the anode from the smell. However, Ba(OH)2 is colorless. I used graphite electrodes for this experiment. Does anyone...

When monochromatic light is incident on a plano convex lens(as shown in the picture), these dark rings are produced which are observed with the help of a traveling microscope. The procedure requires us to measure the diameter of each ring (We need to measure the diameter of at least 10...

At school I and a handful of other kids are devising an experiment to send up to ISS to test it over a period of 30 days next year. (Yep, we're quite fortunate to have this opportunity!) We've chosen to grow piezoelectric crystals using (super)saturated solution of the piezoelectric crystal...

Sometimes I get so bored that I just try to calculate certain experiments I've heard without know the solution. Like using the basic formula to calculate the speed of the moon around the Earth. This time I tried to calculate the differences between 2 clocks, on put on the highest building in the...

For the experiment, we were to determine the relationship between two quantities through linearization after collecting measurements. To verify that P~L^1/2. and determine proportionality constant, C. P=C√L/g= (Cg^-1/2)(L^1/2) Materials used were a timer, string(The pendulum on length), and a...

hello i have a few questions regarding hysteresis loop in ferromagnets as showen here . i had an experiment in which i took a piece of gadolinium and cooled it down using liquid nitrogen , than i put it in an apparatus as showen here , so i induct an oscillating magnetic field on it , forcing...

The research question of this experiment stated "What is the effect of changing the air pressure (kPa) inside a soccer ball on the distance (m) that the ball will travel (when it first hits the ground) as measured by using the AG500 digital air pressure gauge (to 0.01 kPa) and a field measuring...

hello everyone,I want to construct the elliptical polarization in Jones's Matrix form . So, I use the linear polarizer to analyze this polarization. where the Intensity ,which obtain by using the linear polarizer,come from? by integrating overall angle or the other way ?

Homework Statement I am currently working on a physics experiment to confirm the parallel axis theorem. To do this, I have the following setup: In this experiment I change the distance between the centre of the rotating disc and the central axis. I record the time for 5 complete rotations...

Homework Statement Ok so in my lab we have been given a set-up as shown below Minus the horse shoe dector on the right hand side. During this set-up up we need to find the point where the balance point and centre of gravity are equal (as I understand) here is exactly what my script say...

Homework Statement So I recently carried out an experiment for Rutherford scattering. From my lab script is states the following 'Recording the scattering rate as function of angle In order to compare your results with “Rutherford’s scattering formula”, you must first make a correction for the...

Homework Statement So I'm doing an experiment at uni which I have to find out the specific heat capacity of given small solid cylinder. We are given an insulated canister(a dewar flask) standing on a scale where we have to pour Liquid Nitrogen(hereafter will be referred as LN2) in. A cork with...

I'm trying to recreate the results of this paper https://arxiv.org/pdf/1607.08016.pdf to obtain the constraints for the matter density and Hubble constant h. However every time I try to create there results my Fisher Matrix has elements of order of 10^14 which is far to high. I suspect this is...

Homework Statement [/B] Hello, I trying to solve for the minimum value that the x and y components reach in plot (A). I know that you can perform this using IgorPro but I would like to know how to solve for it using Excel. The plot was constructed using the following data points: 110...

Homework Statement I know this is long, but that is only because this question requires me to be thorough, conceptually I think it isn't difficult. To make it easier to read I bolded the important parts. In Physics lab, we were told to conduct an experiment to investigate the effect off mass...

Mod note: Moved from a technical forum section, so missing the homework template. I am analysing the data from my undergrad experiment, which the aim is to find the Plank's constant by scattering x-ray off NaCl crystal and using Braggs law. The straight-line equation is as follows...

Can somebody help analyzing the outcome of the following thought experiment: 1) A simple setup with a photon source, half-silvered mirror and two photon detectors with counters (on each path - A and B); 2) We adjust the setup to get an equal distribution between the counters on paths A and...

we fired off a rocket in physics class and we have to write a report about it. I found out that the height of the rocket calculated using formulas was very off from the real height of the rocket figured out by calculating the tangent of the angle of altitude. (there was an altitude person who...
