Answer:
1. Hydrostatic pressure.
2. Pressure.
3. Equilibrium forces.
Explanation:
1. <u>Hydrostatic pressure</u>: pressure exerted by a stationary liquid. It is simply the pressure in a liquid such as water at a specific depth.
Mathematically, hydrostatic pressure is given by the formula;
Where:
- H.P is the hydrostatic pressure of a liquid.
- rho represents the density of a liquid.
- g is the acceleration due to gravity.
- d is the depth (height) of a liquid.
2. <u>Pressure</u>: it is the force in a direction perpendicular to a given surface area. Thus, it's typically measured in Newton per meters (N/m²).
Mathematically, pressure is given by the formula;
3. <u>Equilibrium forces</u>: a pair of forces whose resultant is zero. It is also referred to as balanced forces because the resultant of all the pair of forces acting on a body or system is at equilibrium (balanced).
Answer:
backup() {
read dirname;
if [[ whereis . /`$dirname` 2> sterr.exe]]
then
mkdir $dirname
for f in . / *.cpp
do
cp f "path_to_dirname"
echo "file backup complete"
}
backup( )
Explanation:
The bash script above is used to backup C++ source files in a directory to a backup directory which is created if it does not exist, and copy's each .cpp file to backup, then sends a message to declare its completion.
Answer:
By definition, <u>multiprocessing</u> refers to the processing of multiple processes at the same time by multiple CPUs.
By definition, <u>multiprogramming</u> keeps programs in main memory at the same time and execute them concurrently utilizing a single CPU doing a context switch.
The first difference is that multiprocessing uses multiple CPUs and multiprogramming to utilize context switch to do concurrency in one CPU. Another difference is that multiprocessing is more expensive but more efficient than multiprogramming due that it allows parallel processing.
Answer:
Yes, this statement is completely true
Explanation:
Yes, this statement is completely true. A personal computer is a multimedia machine and can be used to complete an incredibly large number of tasks with ease. Such tasks include all of the ones listed in the question. Aside from that other tasks depend more on the skill level and understanding of the user. For example, an individual who has a vast understanding of technology and programming can create software to perform absolutely any task they may want or need to do.
