Explain how you think global winds can impact weather in an area.

As the wind travels across the earth, air masses and global winds do not travel in straight lines. in the Northern hemisphere air veers to the right and in southern hemisphere to the left. this motion can result in large circulating weather systems, as air blows away from or into a high or low pressure areas.

on earth the main differences in air pressure are caused by differences in temperatures. cool air produces high air pressure and warm  air produces low air pressure.

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.
