Physics - January 2007

But what if something hit the outside of a spaceship-there would be no sound generated outside because there are no air particles in space but there would be a sound inside right?... because the vibration of the metal from the collision outside would make a sound on the inside but there still would be no sound where it collided outside...



Right?

I believe it has to do with Temperture coefficients

is there a scientific explanation for this?

I am doing some experiments with water and I'll appreciate if somebody can help me to find out water resonance frequency.

Pure wind speed flying in one direction without any debris, etc...

How fast would it have to be to kill a man, at what speed would it rip his arms off or crush his inner organs ?

The above questions obviously parks to one side pedantic things like whether travelling at or faster than the speed of light is possible.

Why do magnets float above a certain temprature? I don't remember what the specific temperature was but it's around minus...... a lot, freezing cold.

This is if both magnets are of equal value.

if a photon of light is massless, how can the force of gravity alter the path of light? eg: light passing in the vicinity of a black hole would bend at an angle which is proportional to the black hole gravitational field. does'nt something needs to have mass to be affected by the force of gravity?

Imagine the end of a gravitational field of a black hole. If I were to travel very close to the speed of light with a course that pulled me along that gravity field, would I accelerate?

DIGGING DOWN INTO THE EARTH PUTS YOU CLOSER
TO ITS CM(CENTER OF MASS). YOU MIGHT THEREFORE THINK THAT
DIGGING DOWN INCREASES THE PULL OF GRAVITY
ON YOU (YOUR WEIGHT), BUT ACTUALLY THE
OPPOSITE IS TRUE. WHY?

F=force
k=proportionality constant
m=mass
a=acceleration.

I recently stumbled upon www.steorn.net who are a company claiming to have developed a device/machine that is more than 100% energy efficient (ie there is a net energy gain) with no degradation of its component parts and no utilisation of its surroundings. It, therefore, appears to voilate one of the fundamental laws of physics - conservation of energy. I think its an attempt at promoting the company, as I'm unable to believe that physical laws can be broken (or of so, then they should be able to provide the theory rather than acting in a cloak and dagger way that they seem to be at the moment!). I'm interested to hear some independent viewpoints.

Around 1996, but I believe the movie is older than that, I saw a movie about a physicist, a mathmetician, and a musician (I think) that discuss atomic physics. I think the work "Mind" was in the title of the movie. The movie was filmed in an old church with a bell? Can anyone give me more information about this movie? I would like to watch it again.

A boat travels up stream in a river with a constant but unknown speed V with respect to water. At the start of this trip upstream, a bottle is dropped over the side. After 7.5 minutes the boat turns around and heads downstream. It catches up the bottle when the bottle has driffted 1 km down stream from the point at which it was dropped into water. Then the velocity of water current is?
