The <span>simple machine found on the head of the ax is </span>Wedge. A wedge is an inclined plane that can be moved. When an ax is used
to split wood, the ax handle
exerts a force on the blade of
the axe, which is the wedge. That force pushes the wedge
down into the wood. The wedge in turn exerts an
output force splitting the wood in two.

Answer:
pH = 2.4
Explanation:
pH is defined as the negative log of the hydronium concentration.
Thus, we can plug in the given hydronium concentration:
pH = -log[H⁺] = -log[0.0042] = 2.4 (two significant figures)
The pH of the solution is 2.4.
P.S: Although I referred to [H⁺] as hydronium concentration, it is more accurate to express it as [H₃O⁺], though they are interchangeable and means the same thing.
