In order to keep the plane travelling at a constant speed, an automatically controlled feedback loop is more reliable.
<u>Explanation:</u>
The main reason behind this is that the plane needs to travel at a constant speed and that would only be maintained by setting constant feedback for the loop.
The feedback being constant will correspond to constant input which will, in turn, correspond to a constant output and hence constant speed.
In the case of using a manually controlled feedback loop, feedback will have to be provided manually at each iteration which is not practically viable as there is a scope for errors.
Answer: A) Battery backup
Explanation:
A battery backup are used to provide the source of power backup to various hardware components and desktop computers. In many cases, the devices are plugged into UPS ( uninterruptible power supply) for backup power and it is also depend upon the size of the UPS.
All the battery backups are located inside so that is why, the devices are heavy in weight. Usually, the battery backup front required additional button for performing various functions.
And the battery backup devices are manufacture by using the varying degree of backup abilities.
