The statement that best describes how the windmill technology benefits the environment is this: WINDMILLS DO NOT POLLUTE THE ENVIRONMENT.
Constructing a windmill involves harnessing the power of the wind to generate electricity. This type of electricity generation has no side effects whatsoever. It is environmental friendly and does not pollute the environment.
Answer:
Alburt Bandura
Explanation:
Rosalind has learned to be impulsive and seldom waits for her turn when playing with other children, this trait she has learned from her father, who is also an impulsive man.
The theorist who would most likely suggest that Rosalind has learned to be impulsive from watching her father is Alburt Bandura. Alburt in his famous Bebo Doll experiment confirmed that children learn from the adults behavior in their life.

The electromagnet is a device that requires conducting wires wrapped around the iron core.
For making an electromagnet, the most necessary item is a copper wire.
What is an Electromagnet?
An electromagnet is a device that has conducting wires wrapped around an iron core. When electricity is passed through the wires, a magnetic field is generated. The setup acts as a strong magnet.
In order to make an electromagnet, a current-carrying wire is needed to wrap around a magnetic material. The current-carrying wires will play the role of conducting wires and the conducting wires are necessary to make an electromagnet. These wires can be made of copper.
Thus, we can conclude that for making an electromagnet, the most necessary item is a copper wire.

Answer: the amount of mass is oscillating is 34.8 kg
Explanation:
Given that;
amplitude A = 20.0 cm
time t = 10 s
amplitude decreases x = 15.0 cm
damping coefficient b = 2.00 N.s/m
amount of mass is oscillating = ?
we know that; amplitude can be expressed as;
x = Ae^-(∝t)
we substitute
15 = 20e^-∝(10)
∝ = 0.02877 s⁻¹
Hence mass m will be;
m = b/2∝
we substitute
m = (2 N.s/m) / ( 2 × 0.02877 s⁻¹)
m = 34.8 kg
Therefore the amount of mass is oscillating is 34.8 kg
