1. Cause-effect: Eva is writing an essay about her school's new computers and their impact on students.

2. Spatial: Kai is writing an informational article about the features of his favorite bike.

3. Problem-Solution: Hank is writing a proposal about ways to fix issues with the student drop-off lanes at his school.

4. Order of Importance: Gwen is writing a speech and begins with her key ideas so that she can emphasize their importance.

Explanation:

When writing compositions different organizational structures are employed depending on the information the author wishes to pass. For example,

1. Cause-effect is employed when the writer wishes to show the relationship between an item and its effect on another. So, when Eva writes about the school's new computers and its impact on students she is trying to establish a cause and an effect.

2. Spatial organization is used when the writer wants to create a mental picture of something. So when Kai writes an informational article about the features of his favorite bike he employs spatial organization.

3. Problem-Solution lists a problem and proffers its solution. This is what Hank seeks to achieve when he writes a proposal about ways to fix issues with the student drop-off lanes at his school.

4. Order Of Importance makes a sequence in the order of events. When Gwen begins her speech with the key ideas to emphasize their importance she uses order of importance organizational structure.

answer: i chose a.

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.
