You are camping and ask the ranger for the directions to a nearby waterfall. he tells you to go 400 meters north and then 400 meters east. you will have traveled about 570 meters northeast from where you started. what is another name for this measurement? a. length b. location c. distance d. displacement

That measurement is your "displacement".

It's the distance and direction from your starting point to your ending point, without mentioning anything about the route you took on the 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.
