The main difference between a compound sentence and a compound-complex sentence is that... Select one:
A. Both have at least 2 independent clauses, but a compound-complex sentence also has a dependent clause.

B. A compound-complex sentence has one independent and one dependent clause, but a compound sentence has one independent and two dependent clauses.

C. A compound sentence has one independent and one dependent clause, but a compound-complex sentence has one independent and two dependent clauses.

D. Both have at least 2 independent clauses, but a compound sentence also has a dependent clause.

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.
