The TA had made the impression that this was a very simple lab so things didnt get as complicated as finding constant of proportionality according to conditions or having to worrying about diameter or percentages. And yes the magnetic field probe was placed in the center of the solenoid to...
The length of the solenoid (Slinky) was 0.83meters and the number of turns in said length was 70 so the turns/meter were 84.3
In a length of 0.83m the magnetic field averaged at 0.097mT
0.70m 0.113mT
0.60m...
The current was kept constant at 1.5A. We were using a LoggerPro software and a Vernier Magnetic Field Sensor to measure the B-field. To alter the turns/meter we would disconnect the circuit and reconnect it at a shorter length of the Slinky. Might assumption be effected by crappy resources in...
Well i was thinking that exponential made sense since u is 4pi*10^-7 in the equation. The slope of this would be from the moving around the equation to n=\frac{1}{\mu*I}*B right? since the graph was B vs. n then the slope would be the 1/uI?
Hello all,
Im trying to do this magnetic field lab and am having trouble with the very last question. It goes: "Assuming the equation (Ampere's Law: B=unI) applies for the solenoid, calculate the value and uncertainty of u (permeability of free space) using the graph of B vs. n.
In this...
ooooooooh ok got it now and ifgured out the work done by the horizontal line on the second problem...thanks for the help...
Hey Andrew, you think you could walk me through the mental process you were trying to show me i want to try to understand it.
ok so it should then be teh area of the triangle right? i tried doing:
W=(0.5)*(Vb-Va)*(Pb-Pa) and I am getting 492J but its not right...what did i misinterpret?
substituting p=nRT/V into the integral wouldn't the constants nRT come out and only integration on p and V be done since p and v vary?
Could you perhaps elaborate some on you method to the first problem and start me off a bit?
ok while I am tryin to digest your advice for problem one...on problem two what would the work be from b to c ? would the intergral thing come up here again?
Hey guys, I am understanding a bit more thermodynamics but I've been stumped once again on two problems:
1) A quantity of air is taken from state a to state b along a path that is a straight line in the pV-diagram
If the volume and pressure in state a are 7.40×10−2 m^3 and 1.08×10^5Pa...
got it ... I am going to try to do it on latex but I am still new at it so its going to take a while to get it right:
part a) \displaystyle{\frac{( p_1+p_a)\* V * M} {R * T_1}}
and part b) \displaystyle{\frac{V*M} {R} * ( \frac{ p_1+p_a} {T_1} - \frac { p_2+p_a} {T_2} ) }
This stuff is...
ok these last few problems have been driving me up a wall an of course its got to be something simple I am missing.
1)
A) Compute the specific heat capacity at constant volume of nitrogen (N_2) gas. The molar mass of N_2 is 28.0grams/mol.
the heat capacity of a diatomic molecule is...
