1.
What is the net overall electrical charge of an isolated n-type semiconductor crystal?
Negatively charged
Variable depending on voltage
Positively charged
Electrically neutral (zero net charge)
2.
The hydrostatic pressure exerted by a static homogeneous liquid of density rho at depth h beneath its free surface is expressed by:
P = rho * g / h
P = rho * g * h
P = rho * h / g
P = 1/2 rho * g * h2
3.
Pascal's principle states that when pressure is applied to an enclosed, incompressible fluid, it is transmitted:
Undiminished to every portion of the fluid and to the walls of the containing vessel
Strictly to compressible gases
With an exponential decay as distance increases
Only downwards towards the bottom of the vessel
