Answer:

"It lets you see the chemicals being absorbed or emitted by the light source. From this you can work out all sorts of things," says Watson

Which of the following statements concerning the nuclear force is false? O The nuclear force is attractive and not repulsive. O

Ulleksa [173]

Answer:

The nuclear force is attractive and not repulsive.
The nuclear force is very weak and much smaller in relative magnitude than the electrostatic and gravitational forces.

Explanation:

Nuclear force is the strongest existing force in the nature.

It has the shortest range.

Its main function is to hold the subatomic particles together in nature.

The nuclear force is created by the exchange of pi mesons between the nucleons of an atom, but for this exchange to happen the particles must be close to one another of the order of few femtometer.
