A worker is using a soft wire brush attached to an electric drill to clean a storage battery. What is wrong with this method? A.
The drill could create a spark and ignite the gases that normally surround a battery. B. The wire brush can remove too much material from the posts of the battery. C. The wire brush could flake off small particles of dirt that can block the vent holes. D. The wire brush could leave metallic deposits near the posts that will short the battery.
The correct answer is letter "B": The wire brush can remove too much material from the posts of the battery.
Explanation:
While cleaning a battery there are several considerations to be taken in order not to damage its function. At the moment of cleaning the posts, we must be very careful since this is the principal contact with the vehicle cables. In front of any damage, the vehicle may not even start.
Thus, using a soft wire brush with an electric drill is not appropriate since it could remove more material than the necessary from the posts.
When volcanoes erupt, they emit a mixture of gases and particles into the air. Some of them, such as ash and sulphur dioxide, have a cooling effect, because they (or the substances they cause) reflect sunlight away from theearth
