A plane is flying with an airspeed of 300. km/h (N30.0W]. There is a wind of 70.0 km/h (S]:Draw an overall vector diagram (label with vectors not just magnitudes) and vector equation b) Find the velocity of the plane with respect to the ground. c) Find the heading the pilot should maintain if he wanted to end up travelling (N30W). Note the plane's airspeed is still 300. km/h.

Need asap ‼️ 20 pts which gravitational force field diagram is drawn correctly? (answers in pictures below)

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°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.

Simon is writing a story about an astronaut whose spacecraft has been boarded by space pirates. the astronaut has her lucky penny in her hand behind her back as the space pirates break into the control room. she has just locked the controls so that the ship is accelerating in the direction of the control room’s ceiling. simon wants the astronaut to use the penny to hit a button on the control panel to turn off the lights and escape. the button is located a short distance behind and below the astronaut’s hands. how should simon use the theory of relativity to describe what the astronaut must do in order to hit the button?
