Explain 3 strategies you can use to take better notes

Taking good notes is an important skill for all students. When you take good notes, you make sure that you understand the concepts that you are studying. It also allows you to study better when you have to go over this information. If you want to improve your note-taking skills, these are some useful strategies:

1. It is important to avoid writing every word that the professor says. Instead, focus only on main ideas and major points.

2. Make sure to follow a structure in your notes by using headings, subheadings, numbers and bullet points.

2. Try to write in a clean and legible way.

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.
