Why is nuclear fision relevant?

nuclear vision provides energy for nuclear power and drives the explosion of nuclear weapons both uses are possible because certain substances called nuclear fuels undergo visions when struck by fishing neutrons and turned into emit neutrons when they break apart

Explanation:

I remember taking this test and seen this on the test and it was correct

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
