Why the not smoking important for the public’s awareness One evidence for importance

One explanation of the evidence

Thank you so much :)

Ammonia, or breathing promblems, or elderly

Explanation:

Because it makes it harder to breate.

if someone is smoking around somebody who has Ammonia, breathing promblems ,or elderly, it makes it harder to breate because of the smoke and nicotine from the ciggerate.

you need to include the text. we have no idea what you are referring to

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.
