<em>The question doesn't ask about anything in particular. I'll compute the net force as a guide, so you can solve your own problem.</em>
Answer:
The net force is zero
Explanation:
<u>Net Force
</u>
If we want to compute the net force exerted on a body, we must add them as vectors, i.e. the horizontal and vertical components independently.
The box has 4 forces, as follow
40 N right
40 N left
10 N up
10 N down
The vertical forces are equal and opposite, i.e. their sum is zero. The same situation happens in the horizontal direction, both forces are of equal magnitude and opposite, their sum is zero. The net force is then, zero in both axes
Answer:
Explanation:
Given
ambient Pressure =98.10 kPa
(a)gauge pressure 152 kPa
we know
Absolute pressure=gauge pressure+Vacuum Pressure
=152+98.10=250.1 kPa or 36.27 psi
(b)=67.5 Torr or 8.99 kpa
as 1 Torr is 0.133 kPa
=8.99+98.10=107.09 kPa or 15.53 psi
(c)=0.1 bar or 10 kPa
Thus absolute pressure=98.10-10=88.10 kPa or 12.77 psi
as 1 kPa is equal to 0.145 psi
(d)=0.84 atm or 85.113 kPa
as 1 atm is equal to 101.325 kPa
=98.10-85.11=12.99 kPa or 1.88 psi
