What makes some collisions elastic and others inelastic?

question 17 options:

if the collision involves sticking together, it is elastic.

if there is energy lost in the collision to sound, heat, etc., the collision is inelastic.

if there is no loss of kinetic energy in the collision, it is inelastic.

if the collision involves bouncing, it is elastic.

If there is energy lost in the collision to sound, heat, etc., the collision is inelastic.

Hope this helps

the answer is

If there is energy lost in the collision to sound, heat, etc., the collision is inelastic.

just did test

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
