Thank you. When the water waves encounter a barrier, it will slow down - so the less water there is, the more "barriers" are in contact. Therefore in shallower water the speed is slower? Is that correct? It would help if the teacher taught us properly instead of asking us to read the...

I'm doing an investigation on how the speed of a wave varies as the depth of water changes, using a tray of water. I know that in deeper water the speed will be quicker than that in shallow water. However I don't quite understand why this is. Apparently it has something to do with Stoke's...

And that's a better way of saying it - thanks :smile:

Interesting, how most of the richer states voted for Kerry...

That's what I didn't do! I now understand why I have to multiply it by two, I didn't think about that earlier! Thank you so much. :smile:

As far as I know, velocity is speed with a direction. I'm not sure on the rest though, sorry.

That's all the information I'm given. The answer is 1.5s, and I still don't know how to reach it! :frown:

Why can't I understand simple vector questions? I've just started a higher physics and that's what we're learning. I'm stuck with this question: A kangaroo was seen to jump to a vertical height of 2.8m. How long was it in the air? I have the answer at the back of the book, but I don't...
