(20 ! ) an object that is 0.5 m above the ground has the same amount of potential energy as a spring that is stretched 0.5 m. each distance is then doubled. how will the potential energies of the object and the spring compare after the distances are doubled? the gravitational potential energy of the object will be two times greater than the elastic potential energy of the spring. the elastic potential energy of the spring will be four times greater than the gravitational potential energy of the object. the elastic potential energy of the spring will be two times greater than the gravitational potential energy of the object. the potential energies will remain equal to one another.

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.
