Answer:
Technician b is correct.
Explanation:
Crimping cable allows a firm connection in mechanical terms and allows a low resistance path for the signal or the current flow, solder although it is better in terms of electrical conduction, can be impractical if the cable is subjected to excessive movement.
A crimped cable with excessive movement can also be easily broken at the ends, where it joins the part of the cable that is crimped, for this reason, a cable that is in excessive motion is recomended to be spliced by joining cable with cable
.
In order to decide which metod is better for splicing cables its necessary to evaluate each situation separatly.
The answer is true. A person can only see object placed at 40 cm from him.

Usually, sound needs a medium to travel through, like a vacuum for example.
Light does not need a medium to travel, and since air is considered a medium, light is not dependent on that.
On the other hand, sound needs a medium to travel through, and outer space doesn't contain space, therefore, no sound.
