Answer:
(1). False, (2). True, (3). False, (4). False, (5). True.
Explanation:
The term ''contouring'' in this question does not have to do with makeup but it has to deal with the measurement of all surfaces in planes. It is a measurement in which the rough and the contours are being measured. So, let us check each questions again.
(1). In contouring, it is necessary to measure position and not velocity for feedback.
ANSWER : b =>False. IT IS NECESSARY TO MEASURE BOTH FOR FEEDBACK.
(2). In contouring during 2-axis NC machining, the two axes are moved at the same speed to achieve the desired contour.
ANSWER: a=> True.
(3). Job shop is another term for process layout.
ANSWER: b => False
JOB SHOP IS A FLEXIBLE PROCESS THAT IS BEING USED during manufacturing process and are meant for job Production. PROCESS LAYOUT is used in increasing Efficiency.
(4). Airplanes are normally produced using group technology or cellular layout.
ANSWER: b => False.
(5). In manufacturing, value-creating time is greater than takt time.
ANSWER: a => True.
Based on the calculations, the absolute pressure in the pipe is equal to 90,670.4 N/m².
<h3>How to calculate the absolute pressure?</h3>
Mathematically, absolute pressure can be calculated by using this formula:
<u>Scientific data:</u>
Atmospheric pressure (Patm) = 1 bar = 1 × 10⁵ N/m²
Head (h) = -70mmhg = -0.07 m hg
Acceleration due to gravity = 9.8 m/s²
Density of mercury = 13,600 kg/m³.
Next, we would determine the gauge pressure:
Now, we can calculate the absolute pressure:
Absolute pressure = 90,670.4 N/m².

Answer:
The entity relationship (ER) data model has existed for over 35 years. It is well suited to data modelling for use with databases because it is fairly abstract and is easy to discuss and explain. ER models are readily translated to relations. ER models, also called an ER schema, are represented by ER diagrams.
