constant in a straight line? How does that increase lift?

Because the faster you go, the more air flows between the wing; thus effecting pressure differences. You follow?

Bernouli's theory still doesn make sense. If you increase thrust lift does not insrease. So that whole lower vs higher pressure thing is invalid.

According to Bernouli's theory upside flying would create high pressue above the wing and lower pressure bellow the wing; thus forcing the plane to the ground.

I was taught that due to Bernouli's theory of air pressure the shape of the wing makes air move faster on the top and slower on the bottom thus creating low pressure above and high pressure below the wing. Now, if this was true, then how do airplanes with identical shape wings fly if both the...

i tried sum(2^k+1) = 2^n+1 + sum(2^k) sum(2^k) = (2^n+1) -1 by our inductive hypothesis (2^n+1)-1 + 2^n+1 2^n+1 + 2^n+1 = 2^n+2 which gives (2^n+2)-1 I think this is wrong

lets say if we compare a mid range desktop with a mid range laptop with the following specs: Desktop CPU: AMD Athlon x3 445 GPU: ATI 5770 MEMORY: 4 GB DDR3 13333 Hard drive: 500 GB SATAII 7200 rpm LCD: 1900x1600 Laptop CPU:core i5 540M GPU: Nvidia Geforce 425M MEMORY: 4 GB DDR3...

Thats a very good link but they don't not mention laptops! :'(

That is actually my question. I am in a dilema between a laptop and desktop. My brother has a desktop but he doesn't let me use it. So I am concern if there are two desktop it would increase the electricity bill a lot.

so let's say if I am going to be using the laptop as a desktop replacement. Then that means it would use the same power as a desktop? I know that if a PSU saids it is 600W it doesn't mean it uses 600W all the time. It means that's the max it can output. I try to do some research and the average...

Would buying a laptop save me a lot more money on my electricity bill than a desktop?
