Meredith tucked her pencil behind her ear and leaned forward to scrutinize the iris. Its unruly petals seemed defiant, almost mocking her effort to sketch them. To her eyes, the flower resembled a random mound of violet-colored whipping cream. But she methodically stared at its parts, one by one, from the green stem up through the ornate petals. Three petals curled out from the base of the flower like stuck-out tongues. Another trio of paler petals stood up fairly straight. Meredith studied how they connected to the flower for several minutes before she retrieved her pencil. Meredith was​

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.

climax. is the answer
