For _1_ long time, i felt like _2_ incompetent fool because i couldn't understand math _3_ science.

which word is correctly used in blank #1?

a. a
b. an
c. and

it wants you to read whatever it gave you. then compare it to the others you read. you need to use textual evidence, and cite anything you do!

hope this !

it means that the hockey puck was traveling very fast.

i could of w this question but i don't see a " passage " .

sorry ! ):

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.
