The air inside a room is at a temperature of 35°c and has a mixing ratio of 7.6 g/kg. a) what is the relative humidity? % b) what is the dew point? °c c) if the room temperature decreases by 5°c per hour, how many hours will it take for the air to reach saturation? hours d) after reaching saturation, if the temperature of the room continues to decrease for one more hour, approximately how many grams of water vapor (per kg of air) will ahve had to condense out of the air to maintain a relative humidity of 100%? g/kg

Which law represents the thermodynamic statement of the conservation of energy of a system? a. the fourth law b. the first law c. the second law d. the third law

(1 point) match the differential equations and their vector valued function solutions. you may wish to multiply at least one solution out fully, to make sure that you know how to do it. you can get the other answers quickly by process of elimination and just multiply out one row element.

16. a brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 n on him. the mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 size 12{1 "." "20"" m/s" rsup { size 8{2} } } {} backward. (a) what is the force of friction between the losing player’s feet and the grass? (b) what force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg? (c) draw a sketch of the situation showing the system of interest used to solve each part. for this situation, draw a free-body diagram and write the net force equation.
