Alright, it does indeed make sense. Thanks a lot!

come on, nobody knows?

humm, I've been wondering: the mass of a nucleus is less than the sum of the masses of the constituent nucleons because of the binding energy. This is how we can get energy out of fusion and fission events. on the other hand, the mass of a proton or a neutron is MORE than the sum of the...

come on guys, I'd really like to know...

why do you say that the equal transit-time principle is fallacious? Is it experimentally false that the air above takes the same time to go across the wing as the air below?

yeah, I thought about that, but why does it not form spots of ice rather than lines? Why is it easier to condensate on the axis of the line than in a random direction next to it?

The last few days have been very cold and when I come back to my car, water has condensated (to solid phase) in the windows. I have noted that the ice seems to form in lines that cross each other (forming seemingly random patterns made of almost perfectly straight lines) Of course there is...

lol, nobody has a serious opinion? And it IS a physics question. We will only be able to travel faster than light if the laws of the universe allow it. I guess it might indeed belong more in general discussion though.

out of curiosity, who thinks we'll ever be able to travel faster than light (either directly or through higher dimensional shortcuts) ?

come on, don't tell me nobody knows

yes, that is not what I was asking. Maybe I misexpressed myself. Let me reformulate. P-inside=P-outside + F-balloon/area. I'm looking to predict what the force exerted by the balloon on the gas will be when the fabric is stretched by a certain amount. I know how to measure it experimentally...

let's say a rubber balloon is not streched (but almost) when its volume is 1L. what force (or pressure) does the balloon exert on a gas inside it when its volume is stretched by xL? I'm measuring this experimentally, but I'd like to know a theoretical way of calculating it.

don't tell me nobody here knows how to do that...

I'm currently going through the IB HL physics, and it's just too easy. Well, I guess it's not any worse than the other college physics programs. In my opinion, it should be modified to include more stuff.

try conservation of energy... also, I believe there is a separate section for homework help...
