Physics - February 2007

I beleive it may be a static problem but my shoes do have rubber soles. It keeps catching me out and is incredibly annoying when I go for the filing cabinet and I get a shock accompanied by a little tick noise. I hate it, someone help me!

If the water level in a dish of water remains unchanged from one day to the next, can you conclude that no evaporation or condensation is taking place?

My Book says Only Force, but I can't see why it can't provide support for Moment as well...

Me and my boyfriend were having a discussion today and we brought up the question whether time travel could be possible someday. I said no, because that would take some sort of magical powers. But he said that people said that Thomas Edison was crazy for trying to event the electric light...

what do you think?


If anyone knows of any news articles regarding attempts for the invention of a "time machine" or advances in the field, please link them here!

I beilive that using magnets and positioning themsleves close together with unequal positive negative charg can creat eletricity by creating a perpetual motion machine using the opisit poles that spin to power the devise. So you have 2 magnets atached to turbine rods. These magnets will be pushing against each other and you may have to make the magnets cut at a 45 degree angle. you then start the motion/rotation of the magnets and hope that the magnets will spin in sens forever using the + and - charg. The spinning of the magnets will then turn turbines to generate electricity. Pls let me know if you think this is even a worth while idea. i have diagrams drawn out but lack any real proof this will work.

What about gravity? isnt gravity instantaneus? Knowing that gravity and mass are directly proportional, if the sun suddenly dissappeared, would the force of gravity continue to hold us in place until the last of the suns light reached earth? I find that impossible, because without mass, there IS NO GRAVITY.
Help me out on this one.

Please help me.

A projectile is fired in such a way that its horizontal range is equal to three times its maxium height. What is the angle of projection?

I understand that we use the equation R = (V^2 / g) sin2(theta)

What i dont understand is what the horizontal and vertical distances should be.

Am i supposed to use the above equation? or should i use:

x = Vcos(theta)t
-h= Vsin(theta)t - .5gt^2

Thank you!

It was -10F today, I left a half a bottle of water in my car. I thought it would freeze and be OK because it was half gone. After work, I picked up the bottle from the cup holder and looked at it and it was liquid, I thought how strange-it's been very cold. And all of a sudden it formed ice crystals and was frozen. Explain please!

i wanna know exactly of what matrial are the neutrons made up of?
dont tell me more n more subatomic particles like neutrino and all...but exactly of what kinda material? ....
its the neutrons themselves which makes up the OTHER MATHERIALS...so what about themselves?
and moreover....what about the PROTONS and the ELECTRONS?
how come they are charged?...we say charging is due to the fact of the dipoles in the materials at an atomic level....but what about the electrons n protons themselves?
please explain if you may....maybe it has got something to do with their spin n all?
i do not know much about the sub-sub atomic particles(like neutrino n all)...i only have knowlege as to neutrons n protons and the like .....which are the sub atomic particles...so dont miss out on the points but as simply as u can (i'm in high school,15)
