If I am to understand Y chromosome haplotypes correctly: Let's say that I am male. I have an X chromosome from my mother and a Y chromosome from my father. Because the Y chromosome is passed directly through my father's paternal line, does that mean I have more in common genetically with my...

Would the human eye be able to pick up a picture from the Hubble Telescope unaided if it were close enough? For instance, how close would I have to be to the Pillars of Creation in order for it to fill my entire field of view if I were floating in outer space? I assume several hundred light...

I have to find the sum of \sum9(2/3)^n and I get a/1-r where a=9 and r=2/3...but I know a=6 and not 9. Can someone point out to me what I am doing wrong? The sum is from n=1 to infinity. Thanks! EDIT: I am thinking I take a(1) which is 6 as the a in a/(1-r), is this correct?

So the energy required to apply 1 N to a 5 m/s object is different than the amount of energy required to apply 1 N to a 7 m/s object? Thanks, you have been a great help.

Lets say we are in space and push a 1kg object with the force of 1N. That object will travel on forever and produce an infinite amount of joules, correct? 1 J for each m it traveled for infinity. EDIT: After reading your last part, I guess not... I keep thinking that the joule is the amount of...

Yeah, sorry about that. I am awful at asking questions. Ah, the coulomb is one ampere second and the ampere is the "constant current which will produce an attractive force of 2 × 10–7 Newton per metre of length between two straight, parallel conductors of infinite length ."

I am a chemistry student and don't know much about physics. I am trying to understand the definition of the coulomb. Correct me if I am wrong please... A Newton is the amount of work it takes to push one kilogram 1 meter per second... Two Newtons would accelerate the object from 0 m/s to 2...

I think I am missing something in Schrodinger's Cat... Wouldn't the Geiger Counter cause the wave function of the decay to collapse because the Geiger Counter is interfering with the wave function? Would the Geiger Counter end the superposition of the particle? Does the problem lie with what the...

I see! thanks!

The force of attraction formula between two charges is \frac{(k)(e1)(e2)}{r^2} How does the inverse of r2 fit into the equation? I understand the concept of how distance would need to be the inverse in the function, but why is the distance (r) in the inverse squared? Is this the same principle...

I think I understand now... Thanks! I still don't quite understand what experiment or sets of experiments that CI attempts to explain.

Maybe I didn't state what I wanted to ask clearly. Please correct me if I am wrong, but doesn't CI state that the photons used to change the state of a particle in the Uncertainty Principle weren't necessarily the direct cause of our lack of information on the particle? I just wanted to know...

Bohr believed that the observer effected the outcome of an experiment at the subatomic level, and it wasn't necessarily the photons used to measure the particle like in Hesienberg's Uncertainty Principle that effected the outcome. What was the basis of this idea if the only way to measure...

In question #1 I was asking why rarefaction occurs, if it is represented on a graph by the wave trough, and what other types of waves besides sound waves (explosion, light, ocean etc.) encounter rarefaction. In question #2 I was asking how group or phase velocity can be faster than the wave...

Anybody? Should I post this in another part of a messageboard, or is my question not clear? Help!
