Consider the incomplete equation below 4he +4he? if this equation was completed, which statement would it best support? nuclear fusion produces elements that are heavier than helium. nuclear fusion produces elements that are lighter than helium. o nuclear fission produces elements that are heavier than helium. nuclear fission produces elements that are lighter than helium. o

i believe it is a.) released into

explanation:

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
