hi need help in physics HW: given current density [J][/→]=[J][/0][x][/Λ] and rotating frame with given surface vector: $$ A^→ = A_0(cos(wt)x^Λ + sin(wt)y^Λ$$ in need to calculate I(t) i tried I = ∫J*dA but i don't know i to technically do the math please help me

that not what i meant. i asked if there is some way to add a condition to my code that identify a force stop (ctr +c) so when i force stop my current supply output is truned off. in a way some if (force stop\ctr +c) turn off device end my main loop is endless i built some homemaide temperature...

i have keithley currnet source that i control with matlab, inside a loop, if i force stop the loop the device continue to output the last current. my question is can i add if condition that turn of the current source? for example if force stop fprintf(device, ':OUTP OFF') end

1. Homework Statement show that tthe transition energy can depend on the number of molecules in the quantum dot according to: E∝1/N^2/3 in a intro course to nanotechnology class the prof gave us this question and said that "its very easy" but i wasnt able to prove this. can someone give me...

no i didnt know, i will try it thank you

yes

i have a problem to find the motion of motion and integrals in a magnetic field given the potential in cylinder quardinate A=(0,A(r,z),0) and i have trouble to even begin with. its part on a course called analitical mechanics with the course book ''mechanics'' by landau lifhsitz' the problem...
