Calculate the second-order correction to the energy for the system described in problem 6.7 and calculate the ground-state wavefunction. account for the shape of the distortion caused by the perturbation. hint. use eqn 6.30 for the energy and eqn 6.27 for the wavefunction. the integrals involved are of the form cos ax sin bx dx da *sin ax sin bx dx = cos (a + b)x 2(a+b) cos ax sin bx dxcos(a-b)x 2(a-b) evaluate the sum over n numerically.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

the independent variable, or the one that is intentionally manipulated is the speed.

so easy. just google the electromagnetic waves and it’ll pop up.
