The strong nuclear force is one of the four fundamental forces in nature; the other three are gravity, electromagnetism and the weak force.
As its name implies, the strong force is the strongest force of the four. It is responsible for binding together the fundamental particles of matter to form larger particles.
to convert m into km we have to divide it by 1000.so,
9426/1000=9.426km
92.2km+9.426km=101.626km.
They speed up reactions by lowering activation energy. Many enzymes change shape when substrates bind.
