Need to put this paragraph in logical order
one lengthy study session in which all academic work is completed leaves the adult student free to pursue the other activities in their life

those activities could include going to work taking care of family. volunteering, or some other activity.

kids get sick work requires overtime. the shortage of volunteers can cause a heavier burden on those who participate

a scheduled block of time can easily be slashed it half or more-by any one of these occurrences

the reality though tends to be incomparable with that idea

the idea of creating large blocks of time is appealing

1) The idea of creating large blocks of time is appealing.  2) The reality though tends to be incomparable with that idea.   3) Kids get sick (when) work requires overtime. The shortage of volunteers can cause a heavier burden on those who participate.  4) One lengthy study session in which all academic work is completed leaves the adult student free to pursue the other activities in their life.  5) Those activities could include going to work taking care of family, volunteering, or some other activity.  6) A scheduled block of time can easily be slashed into half or more-by any one of these occurrences.

Explanation:

The text is about large or small block of time and activities.

So, the first line tells us about the idea of having large blocks of time. The author says it is appealing. In next line we should either expect continuation in favor of this idea or against it, or any possible issues/problems in this idea. So next line (2) tells us that, tough that idea seems appealing but in reality it does not work so well. Next two lines (3 and 4) present examples against idea of creating large blocks of time/activities, first example for kids, and then for adults. Last words in line 4 are about activities. Hence next line (5) talks about which activities those can be. The last line (6) gives the solution (conclusion) to the problem.

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.
