I have a battery load tester that is giving me trouble. A battery load tester is connected to a battery and the voltage can be found. Upon pressing a button on the load tester the circuit is completed between the positive and negative terminal on the battery and the cranking amps of the...

There is a problem I am finding quite confusing: Two particles, with charges of 20.0 nC and -20.0nC, are placed at the points with coordinates (0,4.00cm) and (0,-4.00cm). A particle with charge 10.0 nC is lcoated at the origin. Find the electric potential energy of the configuration of the...

Wow! Thanks for the help guys! And thanks for catching my mistake ehild! I guess that is why I shouldn't work on these problems at the wee hours of the morning.

So would I be correct in saying that : y = e^((-1/2)*x)*[(C1Cos((Square root of 2)/2)*X) + (C2Sin((Square root of 2)/2)*X)] is correct? Where C1 represents some constant and C2 represents some other constant.

I believe that I have worked the problem correctly to the point where I am, however I am not sure how to incorporate complex numbers into my answer? The problem is :Make the substitution v = ln x to solve 4x^2 * y" + 8xy' - 3y = 0. Where " represents double prime, and ' represents prime...

I don't know why I didnt see that right off, I must be working too hard :P I wasnt seeing R as the hypotenuse for some reason. I feel like a dummy for making that second post now heh Thank you StatusX you have been a great help !

Ok so I have Flux = (lambda * length)/permittivity of free space(e) when I set (lambda * length)/e = (2 * lambda/e) * (square root of R^2 - d^2) I get length = 2 * (square root of R^2 - d^2) I am having an awefully difficult time seeing the relationship between these two. I know that...

An infinitely long line charge having a uniform charge per unit length (half-life - if anyone could tell me the correct name for that symbol it would be great too :)) lies a distance d from the point O, where the point O is the center of a sphere. Determine the total electric flux through the...

I am in need of help regarding a problem which asks for the torque exerted by the crankshaft on the load. Initialy I am given that a gasoline engine operating at 2500 rev/min takes in energy 7.89 X 10^3 J and exhausts 4.58 X 10^3 J for each revolution of the crankshaft. I found the...

PV = nRT I just don't see how to plug it in. Pleaseee help its driving me crazy!

I have 5.00 mol of O2(Oxygen) at 20.0 Celsius and 1.00atm. I will compress this to 1/10 the original volume. Find the work? The correct answer is 46.1 Kj I am having a terrible time with this. This is what I know: Q = 0 for an adiabatic process, and the change in internal energy is...

Ok, here is what is given: 1.00 mol O2 Ti = 300K Vi = 5.00L 4400 j of energy transferred by heat to the system Vf = ? Constant Pressure = 29.4 J/mol * K So I set the problem up using Q = n(Constant Pressure)(Tf - T-i) Solving for Tf I find that Tf is equal to 449.7K. Then using...

Yes the assembly looks some what like an xyz coordinate system with all of the centers of mass (midpoints) at the center.

The three rods are joined at their midpoints.

The problem is: Three identical thin rods, each of length L and mass m, are welded perpendicular to one another. The assembly is rotated about an axis that passes through the end of one rod and is parallel to another. Determine the moment of intertia of this structure. Ok what I know is...
