Physics - July 2006

Ok, I copied my physics question from the board and I'm trying to solve it but I can't read my writing for one of the numbers...

I'm not sure if it was :The ship is travelling north with a speed of 48 metres/second OR 4.8 metres/second.

1. A flea jumps from a mouse with a velocity of 4 m/s (East) relative to the mouse. The mouse is walking on a crate that is being pulled at 2 m/s (East 20 degrees North) across the ship. The mouse is walking 1.5 m/s (West 30 degrees South) across the crate. The ship is travelling north with a speed of 4.8 m/s OR 48 m/s and there's a current of 1 m/s (West 40 degrees South). What's the velocity of the flea relative to the ground?

Can you guys please tell me which sounds more logical...if the ship was travelling at 4.8 m/s or 48 m/s. Thanks a lot.

If you guys can actually help me in any way solve it too, that would be even greater but maybe that's asking for too much... anyways thanks a lot for any help!

It seems more reasonable than the bohr model. where can I get details?

I am asking this question in the physics section, because i m hoping for mature answers, backed by science, as I admit my ignorance on this subject

this isnt a question with any right answer just views,

if we never developed to concept of basing physical laws on observation and continued as philosiphers, how far would u think we would have come to this date

For example, I frequently fly between two fixed cities in California and Florida, respectively. Going from California and Florida, it always takes 5 hours and 10 minutes or so. Flying back, it always takes 6 hours and 30 minutes or so. What accounts for this difference?

Has this ever happened to you.
When I've finished washing-up the dishes, I grope about in the warm suds at the bottom of the bowl and it is empty.

Later on when I'm clearing up for the night I pour (the now cold) water away, lo & behold; a teaspoon always appears in the bowl.

I am trying to understand the physics of this phenomenon. Has the hot water disolved the spoon and then when cooling it re-condenses back into cuttlery, or is it in some way able to transport itself to another universe or dimension, and then back home again by nightfall?

Any thoughts??

Gillette double blades were only good for two shaves before becoming dull. Today even the least expensive blade lasts for weeks.

I think it means when an electron moves from one orbit to another, thus emitting light. Or is that wrong?

I'm assuming that photons are affected by gravitational force- when light is being sucked into a black hole, for instance, can some of it achieve a lasting orbit?

In order to work with the relativity equation, surely we must know what system of units are being used. Are they in Metric, Imperial, SI units ISO or some other; or am I being realy dumb.

Can anyone go through a working example for me please?

Ok as I under stand it the big bang theory states at 1 point in time and space that all known matter in the universe converged into 1 area and then was rapidly dispersed and formed balls of gas that formed stars, planets and all known matter in the universe.

There is something illogical about this assessment. That is to say that would not a huge black hole have been formed and all matter would have been a black hole or later consumed by a that same black hole. What was the force that propelled the matter apart? I say it was the hand of god.


Also why is there a dark energy theory isn’t dark energy the ejecti of Black Holes and therefore not be anti-matter. If that is the case 75% of the known universe is Anti-Matter. Also what is cool is their may be anti-matter life forms which we could not even see. Also it has become clear to me that Black holes must function much as a star does internal not as a rock but some form of anti-matter liquid or gaseous equivalent. Thus as it spins it would not spin at the same rate with. This is possibly what causes them to plus from time to time.

Address any part of the question that you want god, science which I think is the study or creation. Thus science by default is the study of god.

Well we know that e.m. radiation induces currents in conductors. Take for example microwave radiation.If it is traveling through a hollow metal waveguide, in the waveguide's walls there will be high frequency induced currents affected by the skin effect.Does light have the same effect?If it does why is it so small compared to other frequencies of the e.m. spectrum? I have an idea but I will keep it to myself right now. Thank You!
