Anon-licensed person may be the sole owner of a civil, electrical, or mechanical engineering business under which of the following conditions

hi your question lacks the options here is the complete question

A non-licensed person may be the SOLE owner of a civil, electrical, or mechanical engineering business under which of the following conditions

(a) A currently licensed California Civil, Electrical, or Mechanical Engineer, as appropriate, is in charge of the engineering practice of the business.

(b) All engineering plans and specifications are prepared by an appropriately licensed engineer.

(c) The name and business contain only the name of the licensed engineer.

(d) None. No provisions exist.

B

Explanation:

Generally a non-licensed person is not allowed to be a sole owner of an engineering business because it requires engineering plans and specifications to be made and carried out hence a certified/licensed  Engineer alone can do that.

from the conditions given the only condition suitable for a non-licensed person to be the sole owner of an engineering business is that the engineering plans and specifications are prepared by an appropriately licensed engineer either working for the engineering business or contracted .

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.
