Answer:
vw = fλ
Explanation:
Sound, like all waves, travels at a certain speed and has the properties of frequency and wavelength. You can observe direct evidence of the speed of sound while watching a fireworks display. The flash of an explosion is seen well before its sound is heard, implying both that sound travels at a finite speed and that it is much slower than light. You can also directly sense the frequency of a sound. Perception of frequency is called pitch. The wavelength of sound is not directly sensed, but indirect evidence is found in the correlation of the size of musical instruments with their pitch. Small instruments, such as a piccolo, typically make high-pitch sounds, while large instruments, such as a tuba, typically make low-pitch sounds. High pitch means small wavelength, and the size of a musical instrument is directly related to the wavelengths of sound it produces. So a small instrument creates short-wavelength sounds. Similar arguments hold that a large instrument creates long-wavelength sounds.
The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength. The wavelength of a sound is the distance between adjacent identical parts of a wave—for example, between adjacent compressions as illustrated in Figure 2. The frequency is the same as that of the source and is the number of waves that pass a point per unit time.

Explanation:
Run: Choose Run when you only need the download once. Perhaps it’s a song or video you only plan to listen to or watch once. Another scenario might be an installation program that, when run, installs software on your machine in other, permanent locations. Once installed, you probably don’t need the installer again.
Save: When you want to keep whatever it is you’ve downloaded, choose Save. You can still run it, or whatever else you’d like to do with it, but you’ll need to do that yourself. You’ll also want to decide where, on your computer, to keep the file.
<em>Save and run: Use this option when you want to do both: save the file to a location you control, and then immediately run it.

Hardware:
-physical parts of a computer that cause processing of data
-can be connected (physically) & can touch
- Hardware wares out during/over time
-Hardware failure is random
Software:
-A set of construction that tells a computer exactly what to do
-software is logical in nature
- dose not have an increasing failure rate
Similarities
- Behavior; Users interact with the products in various ways
- Products produce outputs and given inputs
-they have functional (user facing) and non functional (non user facing) requirements
-They are both complex (any representation of product specifications lead to a main structure)
Differences
- Software is easier to change then hardware
- Software testing is done by specialized quality assurance (QA) engineers, while hardware is done by engineers who are creating the product
-Hardware must be designed and tested to work over a range of time and environmental conditions, which is not the case for software
- Hardware designs are constrained by the need to incorporate standard parts

Final Cut Pro is better for personal use
Answer:
A. Run the parted command.
D. Reboot the system.
Explanation:
Linux command line shell is a vital tooling server administration. It provides the flexibility of executing user and kernel mode commands on the command line interface.
Unlike graphic user interface operating systems, it receives typed commands on its prompt to execute tasks. The fdisk command shows the newly created partition on a disk, and to reload, the parted command is executed or the system should be rebooted.
