Physics - March 2007

it's not the best theory ever but here goes. you know how when people are short of time they usually say "where's all the time going?" or something along those lines, well maybe it doesn't actually go anywhere - it stays in our heads, but we can't remember every single second coz of not enough detail, or just not remembering anything specific.

what do you think of my theory?

Please refer to my previous post via the link above. I was not simply trying to make a point for God's existance, moreso I was trying to make a point that God and Quantum Theory can go hand in hand, and that God himself could be reasonably viewed, from a scientific standpoint, as the cause of our physical universe...and universal laws of physics.

First, my thanks to Blue Sky, for a verry informative, and surprisingly un-biased answer. I would reccommend that everyone read his reply, even though it is rather long.

Scientists more and more are believing that there are alternate dimensions, and that the 11th dimension, in theory, would be the "space" that holds all other universes/dimensions, or however you would like to put it. It would be obvious that outside of our universe, our laws of physics need not necessarily apply. (Once again, I must start a new thread).

If everything paused, and everything in the Universe was stopped an unchanging, does that mean that time would be taken out of the equation altogether? Are there any theories to measure time when time=0 because of change=0 and because time is a measure of change?

I hope this makes sense, I get that it's a moot point because if it stops we wouldn't know or understand, but still, I'm curious if there's any theories for this.

The other end of the string is fixed about a point. The ball rotates about this point at a frequency of 1 Hz/ While the ball is rotating, the string is reeled in until its length r = 3m. If the system is not otherwise disrupted in any way, what is the new frequency of rotation?
25/9 Hz
5/3 Hz
1 Hz
3/5 Hz
9/25 Hz

I asked this question about 40 mins ago, and I got the accelerations for both, but I cant get the tension force? I got 78.4 but the problem says that it isnt right, I dont know what it could be, I tried including g just incase but it said 186.2 was wrong too, any help?

I was watching "Parallel Universes" on the Science Channel last night, which was a very interesting special touching on string theory and super gravity. It was most interesting for me to see some of the Scientists being interviewed, when being asked questions regarding the singularity, that is, that single point of existance which, in theory, went *bang*, for no apparent reason, point which no theory has ever been able to explain, (although string theory does offer an idea, as humerous as it is...)

The following is a quote of what one scientist was saying, and you will have to forgive me, because I was unable to catch his name, but he was either an astrophysicist, or a quantam physicist; it is hard to tell because he made allusions to both. He made a very interesting point, which although had been made before, I had never heard it said in this manner...(I will have to start a new thread here now)

(b) Determine the acceleration of each object.
m/s2
(c) Determine the distance each object will move in the first second of motion if both objects start from rest.

Current theories suggest that entangled particles can influence each other even if separated by vast distances in three dimensions. Is it possible that, although they are far apart in 3 dimensions, they are actually really close or even at the same point in the 4th and/or higher dimensions and thus can influence each other easily through those extra dimensions ? If you accept time as being the 4th dimension, then no matter how far apart two particles are in the first 3 dimensions, if they exist at the same time they are both at the same point in the 4th dimension.

A boat starts from the position (600, - 300) [in part a, the boat's position at time t was (-t + 600, 2t - 300)] and is pointed in the direction N 4Odeg W. Its speed in still water is 2ms^-1, but it
sails in a current of speed 0.5 ms^-1 flowing towards the direction
S 20deg W. Take i to be 1ms^-1 due east and j to be 1ms^_1 due north

ok for the resultant velocity I got v = -1.4566i + 1.062j

i'm stuck on these two questions:

Use the resultant velocity to write down expressions in terms of t
for the x and y coordinates of the boat at time t

Find the distance between the boat an the island position (200, 100)
at the moment when the boat is due south of this position.
