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:
The overview of the given scenario is described in the explanation section below.
Explanation:
- BTS (Binary search tree) tends to be a tree with several nodes noting that perhaps the left sub-tree, along with its leaf, tends to have a key which is less than or equal to anything like the parental node value. The do-tree, including its leaf, seems to have a value greater than those of the key from it's own parent node.
- Binary search algorithm finds a general vicinity in the collection of O(log n) time complexity items whereby n represents the number of elements in the array.
So the provided has never been the binary search trees of its algorithm.
A. 249
B. 342
A string for sure, so answer B.
Answer: True
Explanation:A database is known as the collection of the data and function which can be accessed and managed in organized manner.A database requires the server to provide the services to the application and programs that is known as the database servers.
Database server is provided to the database from the database management system.It is the service for the client-server model of the database.The task undertaken by the server is analyzing , storing manipulation, running etc.Thus, the statement is true.
