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.
Answer:
It is possible for neutral objects to become charged by rubbing them together due to friction. Electrons of one object transfer to the other resulting to more electrons in the object than its protons therefore leaving it as charged

Answer:
18km/h
Explanation:
w - water
s - Swimmer
E- Earth
V (w,E) = 8 km/h
V (s,w) = 10 km/h
V (s,E) = ?
V ( s,E) = V (s,w) + V (w,E)
= 10 + 8
= 18 km/h
