Elements are made up of (a) particles called protons, neutrons and electrons.
The identity of the element depends on how many (a) it has.
The Big Bang is an (a) of space that starts in singularity.
The formula of Einstein’s Theory of Relativity is meaning Energy is equals to mass multiplied by (a) squared.
It is the process when elements are formed inside a star, we call that (a) .
It is the process when the protons and neutrons collided and combined new elements were made, we call this (a) .
For medium-size stars, the (a) is dominant, for massive stars the CNO Cycle is more dominant.
For massive stars the CNO Cycle is more dominant, CNO stands for Carbon, (a) and Oxygen.
he higher the energy of the particles in an object are the higher the (a) of that object will be.
Nuclear (a) is the process when atoms gain enough energy to combine when they collide.
