He solved Ptolemy’s model by proving elliptical orbits.
He proved Galileo’s calculations were incorrect.
He determined that planets move faster when closer to the Sun.
Answer:
It keeps particles that make up protons and neutrons together.
Explanation:
Nuclear force is a short range of force which means it will act at short range of distance like fermi order distance.
This shows the order of radius of the nuclei which means all the neutrons and protons which resides into the nucleus will exert the nuclear force on each other and this nuclear force is of large magnitude compare to electrostatic force or gravitation force between them.
While if the distance is more than the fermi order distance then the nuclear force totally disappears so it will not exist for large distances.
so here the correct answer must be
It keeps particles that make up protons and neutrons together.
Answer:
E=mc2
Explanation:
It explains that in their interiors, atoms fuse together, creating energy.
With smaller mass, object should be more denser in order to have equal landmass.
Mars should be more denser, if it has equal landmass.
But in reality, it's landmass is not equal 'cause it's density is about 72% of that of earth.
Hope this helps!
