A plane has an airspeed of 175 miles per hour and heading of 30.0 . The ground speed of the plane is 206 miles per hour, and its true course is the direction of 34.0 . Find the speed and direction of the air currents, assuming they are constants. Apply the rules regarding the use of significant digits after all computations are complete.

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120Β°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.
