The rock cycle is the process by ehich new rock is made from old rock
Answer:
The correct answer out of the four given options is
option a. light elements with atomic numbers less than 5
Explanation:
Big Bang nucleosynthesis, abbreviated as BBN, also known as primordial nucleosynthesis took place after the Big Bang for about 10 s to 20 minutes and resulted in the yield of isotopes of helium-4 (
), helium-3 (
) which accounts for most of the world's helium, other isotopes of hydrogen in small amounts like deuterium (D or
) and lithium isotope, lithium-7(
) in small amount.
Apart from these stable nuclei, it also yielded two radio-active isotopes: tritium(
) and beryllium-7(
) which due to their unstability later decayed into () and ().
All of these isotopes are of light elements with atomic number less than 5.
Technically it is divisible by 3, but you would just end up with a decimal or fraction as the answer.
A). The conference aimed to encourage particular boundary-crossing explorations of ontological, epistemological and ethical issues that arose from a greater emphasis on a sensitive and even sensuous approach to knowledge and understanding.
b). The variety of places that were explored in this process included, among many others, work and home places, places for vacation, places for the dead, places to pray, places to create, places to destroy and to be destroyed, places to memorialize, places to arrive and to leave, as well as places that disappear and reappear, inside places, and non-places.
