Hello! I need helping correcting the punctuation for this paragraph. ( dont use grammly btw heheeh) -

Dr. Petra Walters director of the Wetlands Science Institute [WSI] said, "The sarus crane . . . should be placed on the endangered species list in order to ensure its survival." Dr. Walters has been with WSI for 12 years: however; she has only been the director for three years.

answer: more info pls

explanation:

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:

i believe the answer is inference
