The measure of the force of gravity on an object, expressed as mass of the object times acceleration due to gravity is called
weight
Answer:
A. Using
Pgauge= Pmanometer
And we know that
Pgauge= deta(hpg)
So deta h = Pgauge/density x g
So
= 7.5(6894.76/1psig)/ 13.6*10^3*9.8m/s²)
= 387.9mm
So to find height of pipe connected to the pipe we say
= h -deta h
= 900-387.97mm
=512.02mm
B. We use manometry principle
Pgas+density xg(25*10^3)-PX density{h-(H-0.25)=0
So
Finally Pgas= 6.54psig
Tasting or touching solutions to identify whether it is an acid or a base is something that you should always avoid since it can be dangerous and, in some cases, deadly.
<span>Phenolphthalein is typically used to test the pH level of a solution. Since you can determine whether a solution is an acid or a base by identifying the pH level, this is one of the correct answers.
</span>However, the question says to "select all that apply," so let's also check the last option, litmus paper.
Litmus paper is commonly used to identify whether something is an acid or a base. When blue litmus paper is exposed to an acid, it turns red. When red litmus paper is exposed to bases, it turns blue.
This means that the answers you should select are both litmus paper and <span>phenolphthalein.
Hope this helps!</span>

Answer:
Displacement
Explanation:
The area under a velocity-time graph is the displacement. Velocity can be negative if an object is moving backwards.
