If different groups of scientist have access to the same data, how can they draw different conclusions?

This may depend on the model in which the scientist is working with, for example, different models see the electrons in different ways, where ones like the Drude model are very simplistic and other ones, like the used for medical physics are a little bit more complex. So for example for the same data, a given number of electrons in a given material, the different groups of scientist can draw different results because they may be trying different experiments in which they use a different models to "think" the problem that they want to solve, where ones may want to see how the material conducts heat (Drude model) and others may want to see how the material can be used in a radiating machine (more complex models)

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.

explanation:

the answer is a. at the equator
