To develop this problem it is necessary to apply the concepts performed to the absolute pressure based on the reference pressure (atmospheric) and the pressure that is generated due to the height of the column of the measured liquid.
In mathematical terms the previous concept can be expressed as

Where
Atmospheric Pressure
Density
g = Gravitational acceleration
h = Height
Our values are given as

g = 9.8m/s


Replacing we have then that



Therefore the absolute pressure in the test section is 99.9019kPa
Newton's First Law: An object in motion stays in motion, an object at rest stays at rest unless an unbalanced force acts upon it. For example, when zipping down the zip line you will stay in motion unless an outside force interferes. ... The more mass the more force needed.
Answer:
A
Explanation:
took the test today at school, got a 95.
Answer:
4N
Explanation:
a = (7-3)/5 = 0.8m/s^2
F = ma = (5)(0.8) = 4 Newtons
