A thermoelectric generator consists of a series of semiconductor elements heated on one side and cooled on the other. Electric current flow is produced as a result of energy transfer as hear. In a particular Experiment the current was measured to be .5A and the electrostatic potential difference...
You are the greatest. I was able to end up calculating everything and got all the answers. Thanks for much for explaining all this to me. You were much more of a help than my professor
Ok I think I understand where you are going with the diagram and it is a big help. I just need some clarification in it since you are using different variables than me.
1. Why is there not an actual buoyant force like there always is? For instance, how come there isn't an Fb = γVsubmerged...
Well I can assume the compression is isothermal so PiVi = PfVf
Pi = Patm Vi = HA
Pf = Patm + γ(h-h') Vf = hA
Where A is the cross sectional area of the cylinder, h is the height of the column of air, and h' is the height of the column of air above the water...
A hollow cylinder with closed ends is 300 mm in diameter, 450 mm high, has a mass
of 27 kg and has a small hole in the bottom. With its axial vertical, it is lowered
slowly into water, and then released. Calculate
a. The gauge pressure of the air inside it
b. The height to which the water...
