Could be easy for some people and hard for some people.
Answer:
1) Tailored software Library management system
2) Utility software Scan viruses
3) Operating system Used to coordinate the hardware of the computer
4) Packaged software set of programs Microsoft office
Explanation:
1) A tailored software, also known as a custom software, is one that is designed and tailor-made only for a particular organisation
2) A utility software is a computer maintenance and analysis software used to enable proper functioning of the computer by performing restorative and maintenance tasks
3) Operating system software
The operating system software controls the operation of the computer hardware within the system and enables the operation of other programs in the computer
4) Packaged software are a collection of programs that are oriented to perform interrelated tasks that a focused to a particular area, such as Microsoft Office.
Answer:
The Gauge pressure at 9 meters depth is ![150 \, kPa](https://tex.z-dn.net/?f=150%20%5C%2C%20kPa)
Explanation:
Gauge pressure is the difference between absolute pressure and some reference pressure, most commonly atmospheric pressure. The increment in pressure caused by a static fluid is given by:
where
is the density of the liquid, g is the accleration due to gravity and d is the depth.
Now, we see that
is linearly proportional to d, and we can assume that
remains constant, because liquids are usually not compressible.
Given that the greater depth is simply 3 times the smaller depth:
![d_2=3\cdot d_1\\9\,m= 3 \cdot 3\,m](https://tex.z-dn.net/?f=d_2%3D3%5Ccdot%20d_1%5C%5C9%5C%2Cm%3D%203%20%5Ccdot%203%5C%2Cm)
at
of depth will also be three times the gauge pressure at
of depth.
We could also have calculated
ny using:
![\Delta P = \rho \,g \,d\\\\\rho = \frac{\Delta P}{g \, d}\\\\\rho = \frac{\Delta P}{g \, d}= \frac{30 \,kPa}{9.8 \frac{m}{s^2} \, 3\,m}=1020.41 \frac{kg}{m^3}](https://tex.z-dn.net/?f=%5CDelta%20P%20%3D%20%5Crho%20%5C%2Cg%20%5C%2Cd%5C%5C%5C%5C%5Crho%20%3D%20%5Cfrac%7B%5CDelta%20P%7D%7Bg%20%5C%2C%20d%7D%5C%5C%5C%5C%5Crho%20%3D%20%5Cfrac%7B%5CDelta%20P%7D%7Bg%20%5C%2C%20d%7D%3D%20%5Cfrac%7B30%20%5C%2CkPa%7D%7B9.8%20%5Cfrac%7Bm%7D%7Bs%5E2%7D%20%20%5C%2C%203%5C%2Cm%7D%3D1020.41%20%5Cfrac%7Bkg%7D%7Bm%5E3%7D)
and used this result to calculate the gauge pressure. These are both similar methods that yield the same result
Higher temperatures means more energy, and a solid phase means the particles are close together. This results in highly energized particles that bump into the particles close to them, who in turn bump into more particles.
im probably wrong but probably increase because if they get closer the static/sparks to cause a reaction
