fundamental quantity help...?

(I)fundamental units:  those units which are the quantities which are independent of each other. All other quantities may be expressed in these units. It turns out that the number of fundamental units is 7. They are:\n(a)length (metre; m)\n(b)mass (kilogram, kg)\n(c)time (second, s)\n(d)luminous intensity (candela, cd)\n(e)electric intensity (ampere, A)\n(f)amount of substance (mole, mol)\n(g)thermodynamic temperature (Kelvin, K)

You need to be a bit more specific about which quantities you are trying to determine.  "Flow" is not a quantity to be calculated.

A lot of physics (especially beginning physics) is just finding the right equation and plugging in what numbers you are given.\nEquations usefull for your problem:\nKE = 1/2*m*v^2 (KE = kinetic energy, m = mass, v = velocity)\nAND\nWork = Force * distance     This is a very important equation\nit's easy to memorize so do it!

Pay more attention in class! And assuming it is an ideal gas, use PV=nRT. Since there is not change in volume you can basically drop it from the equation and make P=nRT. If you like algebra you can leave it in but it will cancel out eventually. You could solve for 'n' first using initial P and T, and then plug and chug.

Mix with a 0% solution in the relation 33:2\n\nSo use 2 units of your solution (like 2 liters) and 33 units of the 0% solution (like 33 liters).\n\nThat's all.

The only way to prove this formula is to conduct an experiment. For the theory, recall that current density j is the fundamental quantity in Ohm's law. Also you will require the Boltzmann energy distribution.

101 - 10^2 = 1... just raise the 2 up a bit.\n\nhope this helps :-)

Pv = nRT\nn = m/M (M Molecular weight)\nPV = (m/M)RT\nP = (m/V)RT/M\nPM/RT = m/v = Density.\nPlug the numbers, watch the units and get the density.\n\nOh a numerical answer, yes, ...42.

... what's the specific gravity of the mixture?\nSince the total volume is the sum of the two ingredients, there was no volume loss due to mixing. (Sometimes there is; water and ethanol are an example.) Then the total mass is 6*0.8 + 5 * 1 = 9.8 kg and the sp. gr. = 9.8/11 = 0.8909 kg/L.

Isn't this supposed to be,\n\nI = PTR/100\n\nThen the answer is,\nR=100I/PT\n\nAnyhow, for your query its,\n\nR=I/PT

Try 1 ÷ 3\n\n1/3 = 0.33333.....\n\n~ ♥ ~

Set up the equation\n\nP = dRT\n\nAssuming P to be constant,\n\ndT = d'T'\n\nor d' = 0.76*273/298 = 0.696 g/l.

Density = mass/volume

by any chance is this a question from your maths homework? lol :D\n\nI cant work it out myself because to put it simple, im crap at maths.

I posted these sources earlier to someone else who was looking for math help.\n\nGood Luck!!

Physics, major science dealing with the fundamental constituents of the universe, the forces they exert on one another, and the effects of these forces. \n\nMeasurement, finding the size or amount of some quantity, and expressing it as a number of defined units.All measurement is based on a comparison. In general, the thing to be measured is compared with something that has already been calibrated, or measured against a known reference.
