i can appreciate you comment. But this is what i mean. This isnt sinking in. My lectures speak to me like this. Could you work through it with me. Cheers
hey guys, i'm in the middle for revising for a dynamics paper in January. I'm in the middle of a 1st year BSc Physics degree. Looking through some past papers, there are questions that i can do, and there are questions that i am unable to do. These are usually question where you have to derive...
hey guys, just wanted to know, in the graph of the OTTO cycle in the link
http://www.qrg.northwestern.edu/ther...Pv-diagram.gif [Broken]
are stage (2-3) and (1-4) adiabatic or not, if so why are they
the reason i ask is that i have a graph showing that these stages are adiabatic...

question
a rectangular plot of land requires fencing on all 4 sides. two opposite sides will use heavy duty fencing at £6/metre, whilst the other tow sides will use standard fencing at £3/metre. if the farmer buying the fencing has £5000 to spend, what is the maximum area he can enclose...
1. ln (x2 / y2)
= log (A / B) = logA-logB
= logx2-logy2
= 2logx - 2logy
(is this correct)
2. can this expression be split into seperate log functions and numbers, is this question the answer
log(2x + 3y) = log(2x + 3y)
(is this correct)
given a distance s = 8.6m, time t = 2s, and a mass = 1.01kg, evaulate the expression to a physically appropriate accuracy?
m3 = 1.013 = 3.03kg
is this correct
are these dimensional analysis questions correct
A = area
V = volume
v = speed
p = density
1. VA / v = L3 L2 L-1 T-1 = L4T-1
2. V2/3 A = (LT-1)2/3 L2 = L2/3 T-2/3 x L2 = L10/3T-2/3
3. 3A3 + 2V2 = A3 = L6
V2 = (L/T)2 = L2T-2 = L4T-2
are these correct
a gas contains 2 kinds of atoms 4x105atoms of type A and 8x105 atoms of type B. it is known that the mass of type A atoms is 5x10-26kg and the mass of the gas is 2.8x10-20kg. what is the mass of type B atom?
answer;
2.8x10-20kg - 5x10-26kg = 2.8x10-20kg - 0.00005x10-20 = 2.799995x10-20kg...
