    What's the difference between an Arrhenius acid and a Bronsted-Lowry acid?

    They both produce H+ right? How do I tell the difference in a reaction?

    Normal force cancels out the force of gravity?

    @Shri13: Van Deer Waals forces are in consistent. Like gravity, they are week forces, but unlike gravity, they appear and disappear inconsistently. The force of gravity is always proportional to the inverse square if the distance between the two objects and directly porportional to the pruduct...

    The Doppler Effect on a still object?

    So the answer is chromatic aberration... That's interesting. It's nice to finally have an answer for this, I've been wondering where the lines were coming from forever. Thanks you guys!

    Normal force cancels out the force of gravity?

    Put really simply, contact force is any force that acts at the point of contact between two objects. The normal force and friction are both instances of contact force. http://en.wikipedia.org/wiki/Contact_force

    The Doppler Effect on a still object?

    I'd check without my glasses, but you said my unaided eyes will do the same thing... If you don't wear glasses, can you make a dark shadow somehow and observe the left and right borders of it really carefully and tell me what you see?

    The Doppler Effect on a still object?

    Well, I got that picture that I used to demonstrate (https://dl.dropboxusercontent.com/u/229171533/Shadow%20Question.png ) right off the internet... And I've tested that with multiple pictures of shadows I've found around google images before coming here... That being said, yes, I do wear...

    The Doppler Effect on a still object?

    Yeah, I didn't really expect it to be the Doppler effect, but I can't think of what else it would be.

    The Doppler Effect on a still object?

    I noticed on my shadow that the left side had a blue outline, and the right side had a red out line, and it sparked my curiosity... It reminds me of the Doppler effect, because I came to notice that the side of the shadow that's furthest from me is always the red one, and the closer side is...

    Question about Warning Coloration

    So, you know how we're taught what to look for on an organism to know to keep away from it? (Ex: The hourglass on a black widow, or the rattle on a rattlesnake.) Well, since animals in the wild can't be taught by other animals the way we can teach, how has it been imprinted in their minds too to...

    Can a Teen Relearn Science to Match Their Teacher Parent's Expertise?

    Wait, this forum has a PM system right? Or some sort of way to msg people? I think I'll just ask about it privately

    Can a Teen Relearn Science to Match Their Teacher Parent's Expertise?

    Wait, so it actually says "Telepathy can't be brought up"? (or some'n like that.) Wow... To be honest that's pretty low. I had such a good question too. ;_;

    That telepathy wouldn't be brought up?
