Happy friendship day aal friend ss...

friendship day ya have some of this friendship

Explanation:

you didn't provide the passage.

explanation:

seeing as this is your first question on i can see why you may have not known that you need to provide the passage.

without the passage, or even the name of the passage, we can not read the passage, therefore we can not determine when or how the pacing effects the tone.

however, you can either repost this question (providing the passage this time)

or you can comment below what the passage is, and i'll you to the best of my ability!

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.
