An evacuated 150-l tank is connected to a line flowing air at room temperature, 25o c, and 8 mpa pressure. the valve is now opened, allowing air to flow into the tank until the pressure reaches 6 mpa, at which time the valve is closed. the filling process occurs rapidly and is essentially adiabatic. the tank is then allowed to sit for a long time with the valve closed, and eventually returns to room temperature. what is the final pressure inside the tank, in mpa? what is the mass of the air that entered the tank, in kg?

Carbon-14 is a radioactive element that undergoes beta decay. which force is responsible for allowing carbon-14 to become stable? electromagnetic gravitational weak nuclear strong nuclear

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.
