Chad and his group are investigating wind power for a research project, and they want to examine the topic from as many different points of view as possible. Which question would most likely generate multiple viewpoints?

1. Where are the primary centers of wind energy?
2 When was the first wind energy farm established?
3. How might the use of wind energy affect the future?
4. Who is responsible for the development of wind energy?

yay another question im really trying to get rid of these points slowly ok- but I also font know them bc I didn't pay attention in school i forgot nwea was a thing:( and no on will let me just give away points so this is my only choice

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
