Draw a picture of the wave, it'll make things easier. And yes, if they are exactly out of phase, they're half a wavelength apart (or 3/2 wavelengths, or 5/2, etc) since the question probably wants you to find largest possible wavelength (since it could get infinitely smaller) all you have to do...

Aha I remember this from vectors in grade 10. Remember relative velocity law: V woman,earth = V woman,water + V water,earth Draw your diagrams, look at the components, add them. find scalar multiple k so that the vertical component is 590 (the width of river) and the horizontal...

remember the i component is (magnitude)cos(angle from + x axis) and the j component is (magnitude)sin(angle from + x axis) then all you have to do is add them, and convert them back into angles and magnitudes (tan^-1 j/i is angle from + x axis, magnitude is sqrt (i^2 + j^2)) Or you can just...

For my independent research project (grade 12) I've chosen to build a generator powered by a mounted bicycle based on electromagnetic induction.(we could choose anything we liked that had anything to do with what we learned during the term) The term has finished and we have two weeks off, I want...
