Homework Statement
The number of particles crossing per unit area perpendicular to X-axis in unit time is N = -D (n2 – n1)/(x2 – x1)
Where n1 and n2 are number of particles per unit volume for the value of x1 and x2 respectively. What are the dimensions of diffusion constant D?
Can...
Newton's universal formula for calculating Gravity: Fg = G Mm / r²
which states that two objects attract each other with a force equal to the product of their masses
divided by the square of their separation,
times a constant of proportionality (G), where G = 6.6742(10) x 10^-11
makes it...
Anyone here knows what or even how to do stoichiometry what i need is the set up to do stoichiometry in dimensional analysis.
i thank you if you can find any info on this matter
i would like to know the steps thanks.
This follows from Buckingham's Pi theorem and is more of a conceptual problem... I'm doing fluid mechanics 101, so everything's kinda new to me.
They say that one reason dimensional analysis is so useful - I'm referring to grouping n variables into n-m dimensionless parameters, where m is...
The piston displacement of a car engine is given as 1.80 liters (L). Using only the facts that 1.00L = 1000 cm^3 and 1.00 in. = 2.54 cm, express this volume in cubic inches. So [tex] 1.80 L \times (\frac{1000 cm^{3}}{1.00 L})(\frac{1.00 in}{2.54 cm}) [/itex]. Would I have to cube the last term...
First off, I'm glad I found a forum like this! Thank jeebus!
I'm a new college physics student that's been out of the science/math arena for about 2.5 years. I'm a Software Engineer by day but I"m going back to get my mechanical engineering degree. Unfortunately I build business systems all...
Firstly, I admit that my math skills are fairly rusty. I also admit that this is a homework problem. It is not to be turned in for a grade however.
The problem is to determine the SI units of G in the following equation:
F = GMm/r^2
(where F is force (mass *...
Hello I've been learning the basics of physics over the past few weeks and thought I knew what they meant when they would refer to the dimensions of something for instance if you asked me what are the dimensions of acceleration I'd say 'change in velocity/time'' or 'v2-v1/T' but I came across a...
Hello I'm learning physics and also brushing up on some math (its been 10yrs) and I encountered difficulty in understanding Dimensional analysis. I don't really understand how they know what number goes on top or what goes on bottom. I've read some explaintations but they just confused me...
Hi I am currently enrolled in PHY138Y1 and I need some major help in some homework questions.I'm a first TIME physics student and I have no idea what I'm doing. I attempted these questions, but I still don't comprehend what the question is asking for. There are some questions that I am having...
In the equation y=c^nat^2, in other words... Y equals C to the N power times A times T to the second power, you wish to determine the integer value (1,2,etc.) of the exponent N. The dimensions of Y,A,and T are known. It is also known that C has no dimensions. Can dimensional analysis be used to...
dimensional analysis (Please help as soon as possible!)
The Space Shutte astronauts use a massing chair to measure their mass. The chair is attached to a spring and is free to oscillate back and forth. The frequency of the oscillation is measured and that is used to calculate the total mass m...
