hi, just out of curiosity. What is the maximum number of photons that can be accommodated in 1 cubic meter? -benzun

A meter stick blances horizontally on a knife-edge at the 50.0 cm mark. With two 5.00 g coins stacked over the 12.0 cm mark, the stick is found to balance at the 45.5 cm mark. What is the mass of the meter stick? I know it is going to be having equal torques. The torque on one side should be...

I have a question ..an ant crawls on a meter strick with acceleration a(t)=t-1/2t^2. After t seconds the ants intiial velocity is 2cm/s. The ants initial poistion is the 50cm mark. So ten \int_{a}^{b}f(t)dt and v(t)=1/2t^2-1/6t^3+c and because v(0)=2m/s the equation is...

Can anyone help me attempt such a project? I basically need to be able to sense the injection pulse in the injector pipe (1/4 inch / 6mm dia.) and convert it to an electrical pulse so that a normal ignition timing light (strobe light) can read the input as it would on a petrol/spark ignition...

An ancient greek philosopher, an ancient greek hero, and Shrodenger's cat walk into a bar. Ok, forget the cat. The philosopher gets so drunk that he decides to prove to the hero that he can't reach the finish line of a 100 meter dash because he would have to go half the remaining distance an...

OHM's Law Lab this lab involved a voltmeter and an ammeter...a voltage source was turned on and sent to a resistor, from the resistor there was a current probe and a voltage probe...the idea of the lab was to give 6 readings for a resistor, each reading would exceed by .5v intervals...during...

A meter stick (L = 1 m) with mass M = 0.409 kg is supported by two strings, one at the 0 cm mark and the other at the 90 cm mark. a) What is the tension in the string at 0 cm? b) What is the tension in the string at 90 cm? c) Now the string at 0 cm is cut. What is the tension in the...

What is the defination of 1 meter? My physics teacher told me it's related to the frequency of a certain EM wave, but he couldn't remember the whole story. Perhaps it also explains why the speed of light is 299792458 m/s, which is an integer.

For the first time in my life, I actually agree with Pat Robertson... Looks like I need a new reality meter also... http://www.au.org/press/pr030318.htm
