Thermal potential energy is converted into electric energy.
Answer:
Explanation:
We have the relation of continuity equation as for compressible fluid flow:
where:
density of the fluid
A = area of cross-section of the fluid flow
v = velocity of flow
For a compressible fluid, the density varies.
It is also called mass flow rate, having unit as kilogram per second and is proportional to density.
The higher the density more is the mass flow rate of the fluid.
Can you please tell what "it" is?
Well, if we've been paying attention in class, we already KNOW that the electrostatic force changes as the inverse square of the distance, and the top graph is conveniently labeled "Electrostatic Force".
But if we didn't already know that, we'd have to examine the graphs, and find the one where 'y' changes like 1/x² .
The top graph does that. After 1 unit of time, the force is 350. Double the time to 2 units, and the force should drop to 1/4 of 350 ... sure enough, it's a little less than 90. Double the time again, to 4 units, and it should drop to 1/4 of a little less than 90 ... by golly, it's down below 30.
The first graph is what an inverse square looks like. Now that you've worked out this graph, you'll know an inverse square relationship whenever you see it.
