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:
A. True
Explanation:
DBMS is an acronym for database management system and it can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
Some examples of a database management system (DBMS) are RDBMS, Oracle, SQL server, PostgreSQL, dBASE, Clipper, MySQL, Microsoft Access, etc.
A DBMS commonly receives data update requests from application programs through the Open Database Connectivity ( ODBC ) driver in case of communication with other database management softwares.
Basically, when a database management system (DBMS) receives data update requests from application programs, it simply instructs the operating system installed on a server to provide the requested data or informations.
If it stores any type of objects mixed, use Object as storage class. All classes inherit from Object and for primitives use their respective wrapper classes. Or just use one of the bazillion container classes that already exist.
My parental figures utilize a wide range of sorts of innovation to help bolster me. For instance, I would state an auto is a gigantic piece of tend to a youngster. When I should have been dropped off at school or move my folks had an auto to enable me to arrive. Another case would be kitchen innovation. My mother dependably cooks for my family and that is a basic piece of developing is nourishment. Guardians can find out about new innovation through the Internet and by assets.
