Tandry cannot figure out how his teacher wants him to answer a short essay question on the test he's taking. where should he look to get more information?
a. in his study guide
c. in the test directions
b. on his classmate s paper
d. none of these

Answer :

C. Tandry should look in the test directions  to get more information about how his teacher wants him to answer a short essay question on the test he's taking.

Test directions or instructions are added to the test papers in order to help and guide students on how to answer the questions properly. So, it becomes necessary to read the test directions clearly before attempting any question in the test paper.

It cannot be his study guide as a study guides are not allowed inside an examination hall unless it is an open book examination. Also, looking on his classmate's answer paper amounts to cheating. So, this also does not amount to a reliable source.

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.
