Answer:
Control valves are used in many processes to control flow, pressure, temperature or other variables. The type of valve used will depend on the size of the pipe, the overall pressure that the system operates, the flowing media, process conditions, and other factors.
Also
A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level.

The controlled variable is the one that you keep constant. The responding variable or variables is what happens as a result of the experiment (i.e. it's the output variable).
Prima facie means the evidence is valid on its face, or based on the evidence, and the elements.

What is prima facie?</h3>
Prima facie, a Latin phrase that means "at first glance" or "based on first impression," The feminine versions of primus, which means "first," and facies, which means "face," both in the ablative case, would be translated literally as "at first face" or "at first appearance." "On the face of it" is a typical translation in contemporary, colloquial, and conversational English.
Prima facie refers to the initial appearance of enough supporting evidence to establish a case, and it is used in modern legal English (both in civil law and criminal law). Prima facie evidence is a term used in common law regimes to describe evidence that, absent rebuttal, would be sufficient to establish a certain claim or fact. In academic philosophy, the phrase is used similarly.

Answer:
After 9 seconds the object reaches ground.
Step-by-step explanation:
We equation of motion given as h = -16t²+128t+144,
We need to find in how many seconds will the object hit the ground,
That is we need to find time when h = 0
0 = -16t²+128t+144
16t²-128t-144= 0
Negative time is not possible, hence after 9 seconds the object reaches ground.
