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.

iv. All Categories
Explanation
In outlook 2016, All categories option is used to change the category name by editing this information. There are different categories represented by different colors. To change the name of the category, Haratio just choose the option of All categories.
Increased inhibitions and a decreased likelihood that all members will contribute to the discussion is the following issues should NOT be expected when interacting with teammates via information technology
b. Increased inhibitions and a decreased likelihood that all members will contribute to the discussion.
<u>Explanation:</u>
In information technology, social behaviour will effect more powerful in industries. In digital medial those use mobile everybody is a media person, easily share the important to social media and sharing person doesn’t aware of the effect of sharing the information.
If a piece of information is received or send both the sender and receiver should be aware of the importance of information make sure it should not be shared outside the group members or the world.
Once import information shared outside the world it can stop any given point time.
Answer:
D is your answer because I'm an expert
Answer: True
Explanation: The potential error in Word is defined as the error that arises when it tries to post some content or text but the user is not sure whether it is posted or not.In Word, the error is relate top the spellings, phrase,grammar etc, in which the Word tries to give alternatives to the particular word or text.
The error is marked with the underline that can be red which means the spelling is incorrect ,green shows some grammatical error and blue is for the inconsistency in the format. Thus, the given statement is true.
