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.
Answer:
Common Internet File System
Explanation:
Given that the Server Message Block (SMB) has various types or variations. The most common variation of this Server Message Block sharing protocol that is considered to be a dialect of SMB is known as "Common Internet File System." This is known to serve as a form of a communication protocol for giving shared access to different outlets between nodes on a network.
Hence, in this case, the correct answer is "Common Internet File System"
Answer:
c. countifs
Explanation:
The key word in the question is "following functions automatically counts cells". So, you can already eliminate answer D.
With COUNTIFS, you can specify multiple criteria based on as many range for consideration.
For example, count this cell, if the value in column D is bigger than 23 <u>AND </u>if the date in column E is lower than June 30, 2019.
It gives great power of filter and calculation to your sheet, almost as good as a database.
Answer:
I believe it is an adapter
Explanation:
An adapter or adaptor is a device that converts attributes of one electrical device or system to those of an otherwise incompatible device or system. Some modify power or signal attributes, while others merely adapt the physical form of one connector to another.
Answer:
I don't think brainly can help on this one chief I think you will have to research the topic and write about it yourself. or just write 3 facts and put spaces until you reach the limit.
