Answer:
Option B
Explanation:
Maintenance-free battery uses Recombination Electrolyte in order to limit the oxygen and hydrogen formation during charging.
Each plate of the battery uses a glass micro-fiber separator that absorbs the whole liquid electrolyte in its pore thus resulting in no free acid.
As the battery charges to its fullest, the oxygen produced at the positive plate moves via the pores of the separator to the negative plate.
Initially it reacts and forms , i.e., Lead Sulphate, then on further charging it gets converted to Pb, i.e., lead.
Due to this, the negative plate is not able to reach the correct potential in order to liberate hydrogen, and hence no water formation takes place.
Thus technician B is correct.
<h2> F = k×
</h2>
Explanation:
- The attractive or repulsive forces which act between any two charged species is an electric force.
- The electric force depends on the distance between the charged species and the amount of charge which can be calculated by the formula given as follows
F = k×
where, K is coulombs constant, which is equal to - 9 x10^9
- The unit for K is newtons square meters per square coulombs.
- This is known as Coulomb's Law.
Answer:When the length of a string is changed, it will vibrate with a different frequency.Shorter strings have higher frequency and therefore higher pitch.
This would be an unusual situation because from what I've learned by studying the moon and the planets in the Solar System when a moon it is orbiting around a gas planet, it is uncommon that the moon could have some forms of life, like in the moon from Star Wars. A moon can host forms of life in an easier way when it is orbiting a rock planet.
