Was he basically saying that the notions of particle/wave duality and uncertainty were silly?

hey guys~ i am having trouble with a physics problem.

An ion's position vector is initially r = 8.0 i - 5.0 j, and 8.0 s later it is r = 5.0 i + 3.0 j, all in meters. What was its vavg during the 8.0 s?

I calculated the change in velocity and got the answer for j, but not for i. I don't understand why I can't get i right.

any suggestions?
thank you!

Two protons that are very far apart are hurled straight at each other, each with an initial kinetic energy of 0.17 MeV, where 1 mega electron volt is equal to 1106 (1.610-19) joules. What is the separation of the protons from each other when they momentarily come to a stop?
? m

I have tried the electric force equaton, but I just can't get the right answer

So, the sky is blue because blue color from the sunlight gets scattered the most during the day. But what about other colors? do they pass through the atmosphere or bounce off? if they pass through the atmostphere, then why don't we see them?

And another question about the blue color. The reason the blue color gets scattered the most is because it has a shorter wavelength? why? why do blue get scattered the most just because it has a shorter wavelength? Is it because that's just how nature works or is there reason for it?

Im realy curious to how a gravitational feild actually works on an atomic level, i dont want an explenation on what it is and what it does. I want a complete explenation to what is physically happening and why. Has it got anything to do with frequency waves? Thanks

I understand how an electromagnetic wave works and what it does and all about the electromagnetic spectrum and all, but what exactly is it in its essence? What is it made of? What is physically happening on an atomic level? We've all heard the example of the waves in the oceon but how does it move throuh the vacuum of space? Thanks

How does light manage to travel through void if there are no particles? How does the "perturbance" get transmited?

I've seen a few references to a link between the two (which sounds pretty incredible). A quick google didnt turn up much - any ideas ?

If they exist why can we not see them? Is it because light requires gravitationl filelds and elromagnetic fields in order to be able to transverse space and the void that these universes exist in has no such fields? Or could it be that they are so far distant that light from them has not yet reached us? The big bang theory states that time and space came into being at that instant. Do you agree that space contains gravitational and eltromagnetic fields because of the condensation of energy into matter and the activity of this matter generated these fields? Is it not logical to believe that at one point there was absolutely nothing in existance and something came into being from that nothingness? If not, how else could it have been?

If i place a campass in the middle of 2 magnets, the magnets were placed in its West n East, something like:

| S (magnet) N | - (Campass) - | N (magnet) S |

2 identical magnets
same distant from the campass
same magnetic force

Where will the campass needle point?

Photons are absorbed when electrons jump from a higher-energy to a lower-energy state.

Photons are emitted when electrons jump from a higher-energy to a lower-energy state.
