An insulated rigid tank initially contains 1.4-kg saturated liquid water and water vapor at 200°c. at this state, 25 percent of the volume is occupied by liquid water and the rest by vapor. now an electric resistor placed in the tank is turned on, and the tank is observed to contain saturated water vapor after 20 min. determine:

(a) the volume of the tank

(b) the final temperature

(c) the electric power rating of the resistor

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?
