Answer:
Schrodinger's cat explains that the state of an object is not known until
an observer observes the state - therefor if the cat is in an enclosed box and the probability of some toxic substance escaping is 1/2, the cat is 1/2 dead and 1/2 alive until its actual state is observed by an external observer. An old saying "is the moon really there if no one is looking at it"
The answer for number 8. Is B.
Answer:
The neutron core is completely destroyed
Explanation:
A earth - supernova is an explosion resulting to the death of a star that occurs close enough to the earth but this does not completely destroy a star. Supernovae are the most violent explosions in the universe. But they do not explode like a bomb explodes, blowing away every bit of the original bomb. Rather, when a star explodes into a supernova, its core survives. The reason for this is that the explosion is caused by a gravitational rebound effect and not by a chemical reaction. Stars are so large that the gravitational forces holding them together are strong enough to keep the nuclear reactions from blowing them apart. It is the gravitational rebound that blows apart a star in a supernova.
