I need to answer this question: a single windmill can produce some energy, explain the use of wind farms and where wind energy can be used to power a whole city?

It is for a science report, so please give as much detail as possible!

Me and my buddies were reasoning in physics class and the question arose: what is infinity minus infinity. Now to me, the answer is quite simple, zero, but i haven't thought it out deeply. Care to differ? No answers promoting individual destructive agendas please.

I had a thought recently that is sociopaths dont have a soul or even have feelings...does that mean that our personality or soul is actually the presence of certain chemicals when we are formed? So basically its all chemistry not divination?

A place kicker must kick a football from a point 32.7 m (= 35.8 yd) from the goal, and the ball must clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 21.6 m/s at an angle of 53.7° to the horizontal. By how much does the ball clear or fall short of clearing the crossbar (enter positive values if the clears and negative values if it fall short)? Also, What is the vertical velocity of the ball at the time it reaches the crossbar? Enter positive values when it is still rising and negative values when it is falling.

I was thinking, what if one of Humanity's most destructive forces went head-on with one of Mother Nature's? In this hypothetical scenario, I guess the nuke would be in the center of the hurricane. What would happen to the hurricane, the explosion, and what would be the resulting aftermath?
