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.
Saudi Arabia produces oil in very large amount and it leads the oil market.
Answer: high pressure over Canada and Asia
Explanation:
Temperature affects air pressure, it should be noted that if the air is warm, they then exert less pressure when they are being compared to cold, dense air.
Semi-permanent features present in the real world the average surface pressure and wind pattern during January are high pressure over Canada and Asia.
Answer:
High heat capacity:
Explanation:
High heat capacity:
Due to having high heat capacity of water, ocean has high heat capacity comparable to land. This is because of large mixing of ocean result in high heating. That is why land heat and cool more quickly than oceans.
and this high heat capacity cause the area near to coastal to have seasonal temperature range
One physical feature is a mountain.
