We know that speed equals distance between time. Therefore to find the distance we have that d = V * t. Substituting the values d = (72 Km / h) * (1h / 3600s) * (4.0 s) = 0.08Km.Therefore during this inattentive period traveled a distance of 0.08Km
Explanation:
It is given that a particle covers 10m in first 5s and 10m in next 3s. so using the equation of motion

Case 2
In next 3s the particle covers more 10m distance. So
20=8u+

s=28.33m
Distance travelled in next 2 sec
s=28.33−20=8.33m

Explanation:
the body is subjected to pressure equals to force force inverse to the area of that body given that it is in motion
Glottis is the organ that is considered to be the opening to the windpipe. It consists of vocal chords wherein voice modulation usually takes place. The production of the sounds of the organ can be mainly attributed to the "buzzing" vibration inside the vocal chords wherein they vibrate.
