Answer:
The force of the atmosphere 200 KN.
Explanation:
Pressure is the ratio of force applied to the area to which the force is applied.
i.e Pressure =
But, Pressure = 100000 pa (100000 N/ ), and surface area = 2.0
Thus,
100000 =
⇒ Force = 100000 x 2.0
= 200000
Force = 200 KN
The force of the atmosphere 200 KN.
The SI base units for length is meter (m) and for time is seconds (s).
The given ratio is
Converting mm/s to m/s as:
Since, 1 mm/s = 0.001 m/s
So,
Since, zeroes to the left side of the non-zero number are not significant hence, the evaluation of to three significant figures and answer in SI units is
.
