Many cultures around the world still use a simple weapon called a blowgun, a tube with a dart that fits tightly inside. a sharp breath into the end of the tube launches the dart. when exhaling forcefully, a healthy person can supply air at a gauge pressure of 6.0 kpa.
what force does this pressure exert on a dart in a 1.4-cm-diameter tube?

force is 0.923 N

Explanation:

given data

gauge pressure = 6.0 kPa = 6 × Pa

diameter = 1.4 cm = 1.4 × m

to find out

What force does this pressure exert

solution

we know here force formula that is

force = pressure × area

here pressure is given and area will be area = πr² = π×

so

force = 6 × ×π ×

force = 0.923 N

answer: he got 23
