Which answer choice best explains why nuclear reactions release more energy than chemical reactions?
electrostatic forces of repulsion are thousands of times stronger than gravitational forces.
gravitational forces are thousands of times stronger than electrostatic forces of repulsion.
the force that binds together protons and neutrons is stronger than the force that attracts and repels protons and electrons.
the force that attracts and repels protons and electrons is stronger than the force that binds together protons and neutrons.

letter c would be correct

The force that binds together protons and neutrons is stronger than the force that attracts and repels protons and electrons.

Explanation:

In nuclear reaction, the two nuclei fuse together to form a bigger nuclei or a big nuclei splits to form two stable smaller nuclei. Strong force binds the protons and neutrons in a nucleus. The difference in the mass converts into energy which very high.

Chemical reaction involves breaking of old chemical bonds of reactants and formation of new chemical bonds of products along with release of some amount of energy.

Strength of strong force is greater than electrostatic force. Thus, the energy released in nuclear reactions is higher than energy released in the chemical reactions.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
