Which statement best describes the author’s viewpoint in "The Thirsty Tree"? Agencies need to stop groundwater pumping and the construction of new dams to restore the American Southwest. Various agencies have implemented plans that were not based on good evidence or a holistic view of the ecosystem. Agencies need to work more closely with individual farmers and environmentalists in the American Southwest. Tremendous progress has been made in eliminating an overgrowth of salt cedar trees in the American Southwest.​

Various agencies have implemented plans that were not based on good evidence or a holistic view of the ecosystem.

Explanation:

I took the quiz. I 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.
