Two objects collide. One of the objects deforms upon collision. What type of collision is this? Select one:

A: Elastic collision, because energy is used to defom the object.

B: Inelastic collision, because energy is conserved.

C: Inelastic collision, because kinetic energy was lost when the object was deformed.

D: Elastic collision, because momentum is conserved.​

True or false graphs must include scales that increase by the same amount

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.
