Technician a says that the reserve rating of a battery is the amount of steady current that a fully charged battery can supply for 20 hours without the voltage falling below 10.5 volts. technician b says that ampere-hour ratings state how many hours the battery is capable of supplying 25 amperes. who is correct1. a only2. b only3. both a and b4. neither a and b.

So here Technician B is correct

Technician B says that ampere-hour ratings state how many hours the battery is capable of supplying 25 amperes.

Explanation:

As we know that ampere hour rating of the battery is the product of current and time

As we know that

here we have

so we can say that ampere hour is the amount of charge that can be flowing through the battery.

So here Technician B is correct

Technician B says that ampere-hour ratings state how many hours the battery is capable of supplying 25 amperes.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
