Homework Statement At the boundary between water (n=1.33) and flint glass (n=1.66), incoming light at ~49 degrees from the normal is refracted. Of course, I can use Snell's law to calculate the angle of refraction. However, my question is whether any of the light at this boundary is also...

No problem!

Can you use E = F/q?

Homework Statement A rhinoceros is calling to her mate using sound wave whose frequency is 5.0 Hz. Her mate is 480 m away. The air is 35°C. How many wavelengths of the sound are between the two animals? Homework Equations v = 331 + (.6)*T v = wavelength*frequency The Attempt at a...

Curious3141, thank you very much for the quick reply!

Homework Statement Which combination(s) would allow the circuit below to turn on the light? S1 = A and S2 = B S1 = B and S2 = A S1 = B and S2 = B S1 = A and S2 = A The Attempt at a Solution I'm thinking that it would be true for the third and fourth ones when S1 and S2 are the same, so the...

Thanks guys! I appreciate the help!

Thanks so much for the quick response -- that makes much more sense now.

If anyone can give me some quick help on this, I would appreciate it. Thanks in advance.

I know that torque is a vector quantity, whereas work is scalar. But, in terms of the distances, what makes torque and work different? Thanks!

Thanks for the responses! I do understand the decimal cases now, and it all makes sense. Thanks again.

You're correct on that. Crossing over yields an enormous possibility for genetic recombination and therefore variation.With regard for question #1, I'm a bit confused as to what exactly it is asking. Even without crossing over, there is still a great number of ways homologous chromosomes can...

Homework Statement I've typed up in Word (it's easier for me to make equations in there) and uploaded as an image below a problem I came across, and I'm curious as to why this works. Obviously, since x,y,z are all positive numbers, if the numbers plugged in are all greater than 1, then it's...

Homework Statement Using the slope from a graph of the square root of the pendulum's length vs period (which would be a linear relationship), calculate the experimental acceleration due to gravity. Homework Equations I'm trying to figure out what equation I can use to solve for 'g'...

HallsofIvy, thank you very much. Your response pretty much summed up what I was looking for (sorry, no pun intended!). I really appreciate it, and understand the concept much more clearly now. Thanks again.
