Force is a vector quantity in which direction matters. This means that the forces will act in opposing directions so the net force will be
22.8 - 2.3 =
20.5 Newtons
The pipe that produces the highest-frequency sound is the 5 cm long pipe.
According to the Fundamental Principle, the length of the tube of the pipe and its frequency is inversely proportional.
This means that the longer the tube, the lower the frequency and vice versa. Therefore, between the 25cm long pipe and the 5cm long pipe, the shorter pipe produces the highest-frequency sound.

For atoms in the periodic table, the given mass number is the sum of the number of the protons (also called the atomic number) and the number of the neutrons inside its nucleus. Mathematically,
mass number = atomic number + number of neutrons
Substituting,
39 = 19 + n
n = 39 - 19 = 20
Therefore, the answer is not found in the choices.
