Answer:
The voltage is 
Explanation:
Generally the half reaction for Zn, Zn2 half-cell is mathematically represented as
⇔ 
(reference study academy)
and the electric potential for this is a constant value
Generally the half reaction for Al, Al3 half-cell is mathematically represented as
⇔ 
and the electric potential for this is constant value
Therefore the cell potential for an electrochemical cell is mathematically represented as
substituting values
The correct reference for this isotope is A. Oxygen-18.
Nuclear fusion is the source of all energy the Sun releases into space. The Sun fuses hydrogen at a steady rate, thanks to a natural feedback process that acts as a thermostat for the Sun's interior (p-p chain). Solar energy production remains steady because the rate of nuclear fusion is very sensitive to temperature.
<h3>Nuclear fusion</h3>
When two or more atomic nuclei join, one or more new atomic nuclei and subatomic particles are created. This reaction is known as nuclear fusion (neutrons or protons). Energy is released or absorbed depending on how much mass the reactants and products have in common.
The atomic nuclei before and after the reaction had different nuclear binding energies, which is how this difference in mass developed. Active or main sequence stars, along with other high-magnitude stars, are powered by nuclear fusion, which releases enormous amounts of energy. Energy will often be released during nuclear fusion that creates atomic nuclei lighter than iron-56 or nickel-62. Both their mass and nucleon binding energy are relatively high for these elements.

Due to electronegativity difference between H and F atom.
<h3>
What is the reason for the difference ?</h3>
- The bond length of HF is 92 pm. It is 16% shorter than the sum of the covalent radii of H (37 pm) and F (72 pm).
- The shorter of the bond length is due to the difference in electronegativity between H and F atom. The electronegativity of F is 4.0, whereas the electronegativity of H is 2.1.
- Greater the difference of electronegativity between the bonded atoms, shorter will be the bond length.
- As becomes smaller i.e. as we proceed from HF to HI, this effect becomes lessens and bond length will be more predictable.
Thus from the above conclusion we can say the difference in electronegativity between H and F atom this is the reason for shorter bond length of HF.
