Answer: Option (B) is the correct answer.
Explanation:
Radiation involves transfer of energy or heat with the help of electromagnetic waves.
For example, radiations from Sun help in transfer of energy or heating of object on which it falls. Like, when radiations are falling on a metal rod then after sometime the rod becomes hot due to absorption of radiations from the Sun.
Thus, we can conclude that Sunlight travels through space without the aid of fluids or solids describes how heat is transferred by radiation
The atomic mass of beryllium (Be) is 9 g/mole
Now, 1 mole of any substance contains avogadro's number of that substance. Therefore:
1 mole of Be contains 6.023 10^23 atoms of Be
In other words:
9 grams of Be contains 6.023*10^23 atoms of Be
Therefore, the mass corresponding to 9.76 * 10^12 atoms of Be is:
= 9 g * 9.76 10^12 atoms/6.023*10^23 atoms
= 1.458 * 10^-10 g (or) 1.46 * 10^-10 g
The correct answer to your question is water. So I believe letter D. Plus there's not another reaction in nature that's Biotically. Also meaning water also goes up the stems on plants.
Answer:
