Q. A truck loaded with sand accelerates along a highway. If the driving force stays the same on the truck, what happens to the truck's acceleration if its trailer leaks sand at a constant rate through a hole in the bottom?
Ans.
If the force stays the same, but the mass steadily decreases then the acceleration must increase (F = ma)
Explain quasi-static isothermal expansion A method is reversible only if it is quasi-static and non dissipative. E.g. A quasi-static isothermal expansion of an ideal gas
