An airplane needs to attain a speed of 480 feet per second in order to take off. If the airplane has a maximal acceleration of 12 feet per square second, how long (at a minimum) must the runway be in order to accommodate the airplane for takeoff

c. newton's third law of motion

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

the answer to this is proletariats.

hope this : )

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
