Aclosed, rigid tank is filled with water. initially, the tank holds 9.9 ft3 of saturated vapor and 0.1 ft3 of saturated liquid, each at 212°f. the water is heated until the tank contains only saturated vapor. for the water, determine (a) the quality at the initial state, (b) the temperature at the final state, in °f, and (c) the heat transfer, in btu. kinetic and potential energy effects can be ignored.

Which of the following are guidelines to follow for obtaining accurate observations

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
