Aah, sorry. Here's the diagram. It's the one to the left under 6.9. (https://goo.gl/Pc87AW) Momentum is conserved. Don't think there's more to be said than that, is there?

I'm sorry if this question is trivial. It's just I cannot seem to wrap my head around how I can use momentum conservation with kinetic energy conservation to find this ratio, especially when I have no idea what the other velocity is.

Homework Statement A particle of mass m and initial velocity v0 collides elastically with a particle of unknown mass M coming from the opposite direction as shown in the left-hand sketch on the next page. After the collision, m has velocity v0/2 at right angles to the incident direction, and M...

Well, to be honest I understood very little of what you said, but that's because I haven't touched these topics yet. (I'm self-studying thermodynamics). Time to explore these new topics! Thank you! (on a side note, would you happen to know of a good thermodynamics book? The one I'm using isn't...

Okay, so once the air is saturated, it won't take in any water. So, the amount of water that causes full saturation is our evaporated water. Everything else freezes. How do I find the amount of water that causes saturation?

The sun? Not a possibility due to zero heat flux. I'm guessing this has something to do with the wind, but can't quite nail it. If there's no temperature change, only phase changes can occur as they do not rely (directly) temperature. (But how on Earth am I supposed to send water to 100C for...

Shouldn't there be zero heat flux as the temperature is the same? Or did I get it wrong?

Homework Statement Wet clothing at 0°C is hung out to dry when the air temperature is 0°C and there is a dry wind blowing. After some time, it is found that some of the water has evaporated and the remainder has frozen. Estimate the fraction of the water originally present in the clothing which...
