I would think that persons B and C will agree with each other on the time and the distance. Person A will disagree.

I agree, it's best to save the brain cells for old age, we might need them :cool: but I just can't resist....:D I'm coming up with 7.7 x 10^-13 m/year/m Oh dear, it's even smaller! I don't think...

So we are comparing the amount of air used with the amount of air drawn into the engine. We are doing to need to convert the volume of air to a mass. Can you calculate the density of air so we can do...

With static charges the electric field can be described as the gradient of a scalar. It is therefore irrotational. The work done in moving a charge through the field is independent of the path taken...

Yes it's do do with atmospheric pressure. You wouldn't be able to do on in the moon. This actually is how barometers measure the atmospheric pressure. Barometer - Wikipedia, the free encyclopedia...

You don't. It is B tan@cos@ in one frame and B sin@ in the other (which are of course identical). The cos@ term comes from taking the component of the flux perpendicular to the plane of the loop and...

It might be useful to imagine what happens when you remove your finger. With a drinking straw the liquid will run out, but with a coffee stirrer it might stay in.

I don't won't to get of topic here, but chaos is quite different to randomness. The first is deterministic the second one isn't.

Good, let's work in stages. First of all Are you able to calculate the energy that is not reflected/scattered using the attenuation coefficient?
Liked On: 09-26-2014, 05:34 PM
You are right, the energy will be the intensity x time. But let's just work per second for now. So if the net intensity absorbed = the inflow - the energy dissipated, we need to find the energy...
