Which pronoun goes into the blank if the dog's sex is unknown?
the dog stretched
_limbs, yawned loudly, and then began to look bowl
a) her
b) his
c) it’s
d) their

The answer is C)it's

Explanation: If you read the sentence, it makes sense and it is not exactly explaining a gender.  The dog stretched it's limbs, yawned loudly, and then began to look for it's bowl.  

It would not make sense if it was The dog stretched their limbs.  Their is for more than one person or another person, as in a possession.  It would make sense to use their if there was more than one dog.  The dogs stretched their limbs.

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.
