Testing

Explanation:

This is basically asking you what the next step of the scientific method is. First, you would ask a question. Next, you would research that question to get some background information. Once you have that information, you would create a hypothesis (typically "If..., then..., because..." format). Then you would conduct an experiment to test your hypothesis. Then you would gather data, draw conclusions, and see if your hypothesis was correct.

Hope this helps!

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.
