Art thou that beowulf with breca did struggle,
on the wide sea-currents at swimming contended,
where to humor your pride the ocean ye tried,
’twas mere folly that actuated you both to risk your lives on the ocean.
from vainest vaunting adventured your bodies
in care of the waters?

in the water’s possession,
ye toiled for a seven-night; he at swimming outdid thee,
in strength excelled thee.

the pledge that he made thee
breca outdid you entirely.

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.

explanation:

it would be d because the however is more proper and the comma is placed in the right spot
