Heat moves through liquid and circulates due to density a. radiation b. conduction c. convection d. water cycle a. radiation when the electromagnetic radiation in a region of space is at equilibrium with its surroundings, it can be described by the planck radiation formula. [ the total energy radiated from an area in this region of space is given by the stefan-boltzmann law and the energy density associated with the radiation can be related to that law. in the development of the expression for the

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

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.

Me with this and you will be marked brainliest
