1. Homework Statement
Given that (x-1) and (x+1) are factors of px^3 + qx^2 - 3x - 7 find the value of of p and q.
2. Homework Equations
Not sure but I think ou have to solve as simultaneous equations.
3. The Attempt at a Solution
I am completely lost and have no idea where to...
Thanks for the help. :smile:
Using 0.6m as length and 0.001m as the cross sectional area I have derived an answer of 3.06 x 10^-5 after first findinng the resistance of both wires (as you stated) then using the resistance found in the equation V = IR to find the potential difference...
Hello everyone, as you can tell I'm new and just wondering if I could get some help with this question as I'm not sure where exactly I've gone wrong:
1. Homework Statement
Two wires are used to connect a lamp to a power supply of negligible internal resistance. The potential difference...
