Answer:how long it took him to get there
Explanation:
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.
The series circuit is the one in which the current flowing through each bulb will be the same as the current at point x.
<h3>What is a series circuit?</h3>
When bulbs are connected in series, the bulbs are connected in an end to end manner. The same current flows through all the bulbs when they are connected in series.
As such, the series circuit is the one in which the current flowing through each bulb will be the same as the current at point x.

Answer:
Explanation:
According to Faraday-Newmann-Lenz, the induced emf in the loop is given by:
(1)
where is the rate of variation of the magnetic flux through the loop.
We know that the magnetic flux through the loop is given by
where B is the magnetic field and A is the area of the loop. Since the magnetic field is constant, we can write the variation of flux as
So eq.(1) becomes
and the problem gives us:
is the magnetic field
is the rate at which the area changes
Substituting into the equation, we find
