When as young as 18 weeks old, Dr. Patricia Kuhl found that babies can listen to “ah” and “ee” vowel sounds and gaze at the correct, corresponding lip shape on a video monitor.
Around age 2-3 months, infants start coping and making soft vowel sounds. They are able to do this because their larynxes and other parts of their throats change to allow these sounds.
By age 3-4 months, babies begin to make consonant sounds of b, k, m, g, and p.
By 4-5 months, the vowels and consonants are put together to form nonsense words.

The answer to this question is 22.
The workdone by the tension is; Positive
<h3>What is Tension force?</h3>
This question is from an elevator that is held by a single cable which is ascending but slowing down.
Now, this elevator is being acted upon by two vertical forces known as Tension which is upwards and the weight of the elevator acting downwards.
However, the direction of motion of the elevator is in the same direction as the tension in the cable. Thus, we can say that the work done by tension is positive.
