Physics - December 2006

this is related to robotics with LEGOs and gears. My vehicle is using two 9-Volt motors and I turn by making one motor go forward and the other motor going backwards. PLEASE HELP! anyone who does crap answers will be reported to Yahoo! Thanks in advance!

This is what my maths tutor at college told me whilst we were doing exponential functions. But I have heard about a Planck number. Is this the smallest amount of energy possible? So when the water reaches this temperature above room temperature does it then drop to room temperature again? Is my tutor wrong?

I always wonder why must E=mc2. Since scince need very accurate farmular, this formular seems a little bit too ideal. Why not E=mc3 or E=mc0.13157668464164984651684984654684...... something. If Energy really = mass * speed of light square, pleeeeeeeeeeeeeease tell me how Einstain's bloody hell intelligents prove it.

I'm doing a science fair project growing plants in some G-Force. They will be spinning at a constant rate on a disc. How do I calculate the G-force that is being applied? Thanks!

Some psychologists compare our consciousness with iceberg.
The small visible part of this iceberg is our logical consciousness.
And the unseen (underwater) greater part of the iceberg is
our subconsciousness. Therefore they say, the man uses
only 10% of possibility of his brain.
And if it so, why doesn,t anybody teach us how
to develop our subconsciousness.
I think it is because there are few people who understand
that the processes of subconsciousness are connected
with quantum processes. The subconsciousness theory
closely united with quantum theory.
These quantum processes which take place in lifeless
(inanimate) nature also take place in our brain.
Our brain can be the laboratory in which we can
test the truth of quantum theory.

1. Nonlinear dynamic process.
2. Vacuum process.
3. Superconductive process.
4. Holographic process.
5. etc.

An online physics text after several editions consists of a page of erroneous facts regarding the kinetic energy theorem. These errors where discussed on this site and were resolved in the authors disfavor.

In summary He asserts
1. In kinetic energy theorem K=1/2mv^2, the 1/2 is an arbitrary constant whose value is dependent on the unit system used. Under the metric system the constant is 1/2. The metric system was used to make the kinetic energy equation more managable at
the expense of other formulas.
2. the equation cannot be derived from principle but must be experimently determined.

RESOVLED-The THEOREM is mathematically derived. The 1/2 constant is independent of units.

I emailed him and unprosumptiously pointed out the error. However, he still asserts he is correct using arguments that rely on his initial error.

I want to give up because I don't think he will listen, but it bugs me that other students will be learning incorrect information.Should I pursue it further?

Are there any types of waves (sound, light, etc) that exist where the points above and below the mid point are not the same/equal inversely.

I was looking at a sound wave and wondered if it would be possible to have a wave with such characteristics. Thanks for your time...

Imagine you are underwater, sitting on the bottom not too far down - say 10 meters / 30 feet or so. You are presumably breathing using SCUBA gear. Forget about the inconvenience of the mouthpiece or whatever. I am interested in pressure, how much work you have to do to push your breath into the balloon. Do you have to breath / push harder, push air at a higher pressure, into the balloon to inflate it than if you were at the surface?
