Describe Hopewellians

Explanation:

a wide scattering of people who lived near rivers in temporary settlements of 1-3 households and practiced a mixture of hunting, gathering and crop growing

Explanation:

The Hopewell tradition (also called the Hopewell culture) describes the common aspects of the Native American culture that flourished along rivers in the northeastern and midwestern Eastern Woodlands from 100 BCE to 500 CE, in the Middle Woodland period.

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.
