ok sounds like i'm on the right track. Just a little more, if frequency is constant. Increase in intensity the same as increase in power will eject more electrons. How does that work, more energy per length of time is distributed over each electrons, so more electrons ejected right. Now how...
Hello my question involves what exactly is the frequency and intensity of the light. The E = hf applies to the photon particle aspect of light right? So where is f from, the wave aspect? Also increase f, which increases E makes the electrons eject faster in terms of kinetic energy right, but...

It's an equliteral triangle
I'm suppose to find the area of the shaded region. first of all are the chords of each those regions half 5cm? Should I find the areas of the sectors and then subtract the areas of the triangles...
if i do use triangles, what length do i use, the radii and what else, i am almost there.
and my nephew hasnt taken trig yet, not sure if i can be any of help if i explain to him.

To determine the shortest rope that can be wrapped around the two circles
any ideas? i have forgotten everything about geometry. My nephew asked me this
the question is A plane wave of 400-nm light is incident on a 25-µm slit in a screen, as shown in the figure below. At what incident angle will the first null of the diffraction pattern be on a line perpendicular to the screen?http://img130.imageshack.us/img130/9766/inter9ax.jpg [Broken]

At this moment I would really like to know what hybrid animals are you taling about?
Needbioinfo, who are the people that are doing this? Where were these experiments conducted?
