Ah right, ^-19 Thanks

Wow stupid, Planck's constant is J×s which is kg*m2/s Well, everything else looks okay?

In case I'm wrong, the formula for energy of a photon is E=hf. Or E=hc/λ, because f=c/λ. Basically the second formula is just in case you don't know frequency so it crams the equation for that into the equation for energy. When I use E=hc/λ the units I get are... kg*m2/s3 What I did was... A...

I saw an experiment where they were trying to determine if Antimatter fell down or up in a gravitational field. They don't have results yet. It got me thinking, we say matter and antimatter have opposite values for everything except mass. What if the mass is somehow different? negative mass or...

Thanks for the replies, reading over them now. I got a warning "Asking questions cold " Is this because the question is so short and vague? If so, my bad, won't happen again.

I don't think that can be said with certainty that it would have been impossible for such a thing to happen but I do agree the chances seem slim.

From videos I've watched it seems that they do break it down into two components (electric and magnetic) and each component has specific influence on a charged particle passing through the field. This is what I don't understand. Like for example in this video he says... "First let's determine...

So the answer is, as far as we know thus far, there would be no difference in the emmision spectrum. However we could expect to see specific high energy gamma rays from annihilation of matter and anti-matter particles, unless there is a mechanism we do not yet fully understand like one...

As far as I know, matter and anti-matter are only different in charge and spin. Therefore a star undergoing fusion reactions with anti-matter should give off the same light spectrum we see with fusion reactions in a star comprised of matter, so it would show the same absorption lines. Would...

Can someone explain the difference? thanks.

Thanks for clarification. Also, I never meant to imply that we perceive a change in time, it is relative to someone else.

Gravity and speed through space has an effect on time. Increased gravity = slower time Increased speed = slower time When we look out at the stars and measure their spectrum, we see a red shift. This red shift is the result of the increase in the distance between the source of the light...

Sounds rough, thanks for the info. I might know someone taking Physics 30 soon so maybe I can check out their notes/questions too. I'l definitely watch the Khan videos

Would it be different if the nuclei were one particle? Shooting other particles at it would transfer energy and possibly allow that particle to break into separate particles, just like how we think it knocks a proton or neutron loose. Could it or why not? You said 'not atom', So the kinetic...

Many thanks Turk, Yes I am in Alberta, good guess :smile: Yeah I have been watching some videos on that site to catch up on a few things. So a big part of physics 30 is splitting up the momentum of objects in each dimension?
