Read the following passage:

i awoke to the sound of footsteps outside my door. why would someone be awake at this hour? hungry maybe. stomach growling. food. sounds good. maybe some cold pizza. should be some left. who's out there? i should go check. which best describes the effect that the use of sentence fragments has on this passage?

a. it makes the writing more accessible by using simplified language.

b. it adds emphasis by capturing the character's unstructured thoughts.

c. it speeds the pace of the story to create a sense of urgency.

d. it slows the pace of the story to create a mood of suspense.

either online or traditional classroom can work for students. which is better will depend on students and teacher. students may have trouble following a lesson in classroom while they can study at their own pace online. other students may have trouble staying focus on their own in online classes. teachers are more used to classroom teaching but they may also be more worry about their jobs teaching online classes and work harder.

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.
