Review questions 1. Explain what it means to resolve a vector.
2. Draw simple vector diagrams and resolve them into two
components.
a) 60 N at an angle of 30° from the horizontal,
b) 45 m/s at an angle of 80° from the horizontal.
c) 1900 km at an angle of 40° from the vertical.

Vector Resolution is a process where one vector is broken down into two or more smaller vectors.This includes the process where one vector is broken into two components,which was discussed in much more details in another lessonbut we can also use vector resolution to find a missing vector

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.
