Aclosed cylindrical tank that is 8 ft in diameter and 24 ft long is completely filled with gasoline. the tank, with its long axis horizontal, is pulled by a truck along a horizontal surface. determine the pressure difference between the ends (along the long axis of the tank) when the truck undergoes an acceleration of 5 ft/s2.

Explanation:

We shall use newtons second law to evaluate the pressure difference

For the system the forces that act on it as shown in the figure

Thus by Newton's second law

Mass of the gasoline can be calculated from it's density

Using the calculated values we get

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

object 2 because all the other ones are wrong
