Determine the acceleration that results when a 12 N net force is applied to a 3 kg object.

Heya!!

For calculate aceleration, let's applicate second law of Newton:

⇒ Being:

→ F = Force = 12 N

→ m = Mass = 3 kg

→ a = aceleration = ?

Lets replace according formula and leave the "a" alone:

Result:

The aceleration of the object is of 4 m/s²

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
