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...
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...
