Which equation best captures the following logic: A car starts when doing all of the following: the keyless fob is within a specified proximity, the driver presses the brake, the driver presses the start button. Inputs: k: key within a specified proximity, b: brake pressed, s: start button pressed Output: c: car starts. c = (k + b)s
c=k(b + s)
c= kbs
k + b +5

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
