Now how many decibels of sound intensity are being produced

Think of a number. Any number. That number is how many thousands of years old a certain rock is. That number is how many times someone has cried in their life. That number is the lucky number of an unlucky man who is yet to realize he is unlucky.

Think of a number. No, think of…numbers.

Picture all of these abstract representations of human thought, all of them forming an imagined pattern, as all patterns are imagined, and picture how those abstractions describe, in specific ways, real moments that exist.

Picture numbers.

There is a woman who lives at 531 Beachwood Street. Her phone number starts with a 3 and ends with a 5. She smiled 18 times yesterday. She is currently thinking of 3 things she needs to do. There are actually 4 things she needs to do. She has forgotten 1 of them.

She touches the doorknob 2 times before committing to its turn. She has 2 eyes. She has 2 hands. She has 2 more chances to make her life what she thinks it should be.

But she doesn’t know it yet.

Think of a number.

Yes! That’s the one! That’s the one that describes an infinity of disparate truths about our disparate universe.

Also, the roads are looking clear.'

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.
