Focusing on a writers would be most when providing feedback for revision.
a: word count
b: font type
c: use of support
d: spelling

the correct answer is c. he speculates on what might happen at given points in the future in a world without people. alan h. weisman is an american author, professor, and journalist. authors organize their information with a purpose. they present their ideas in an organized way. this is called text structure. weisman uses text structure so as to improve overall comprehension and to prove his points.

halloween: it’s my favorite holiday

halloween is one of the best holidays for some people but it can also be scary for others. halloween is a holiday where some people believe spirits and soul of the dead that haven’t moved on will come back again to haunt the lives of the living. this is why many people dress up in costumes to disguise themselves as someone else. some people like us wish to be something that we would benefit in life from. like angels of god. some dress up just to be unique from the others. many families stay home and watch scary movies and others dress in their tremendous costumes and knock on each door to either get a trick or a treat.

personally everybody loves halloween because i could be someone else one day out of the year. it’s fun and entertaining, especially for kids. halloween also has a lot of history. many myths and beliefs say that witches and warlocks are alive and living among us. is this a trick or a truthful treat?

halloween may have secrets and scary things behind the door but we love halloween and it is beautiful to see how happy children are when each door opens full of treats and goodies. it makes everyone happy. happy halloween day.

happy to .

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.
