A two-dimensional array has been defined to hold the quantity of each of 5 different healthy snack products sold in a tuckshop d

uring the past three months. The array is declared as follows: sales = [ [ 0, 0, 0, 0, 0], [0, 0, 0, 0, 0], [0, 0, 0, 0, 0] ] Indexing of the array starts at 0, so the sales of the first product in the second month is held in sales[1][0].

A unique aspect of Java that allows code compiled on one machine to be executed on a machine of a different hardware platform is
notka56 [123]

Answer:

Java's bytecode

Explanation:

To execute its operations, java programming languages uses bytecodes.

These bytecodes are literally instructions of a java virtual machine (or JVM). They are generated in form of a class file as soon as the java program is ran and executed. In other words, the java compiler compiles the code and generates the bytecode.

As soon as the bytecode is generated, it can be transferred to a different machine and platform completely and one can run this bytecode on this different machine.

. What is the relationship between frequency, wavelength and speed of a wave?
jeka94

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.

How do you put sound/music in Google classroom slideshow?
Svet_ta [14]
So, there's no actual way to insert music into your slides unless you use imovie. BUT, you can place a link in one of your slides to a particular song on spotify, and as you are presenting, you can click on the link, and it will open up spotify and play the song you selected. 

Okay so first, go ahead and open up your google slides presentation. 

Then find the specific slides you want to add music to. 

Select Insert from the menu, and then click on text box. Place the text box anywhere in your slide, and you can put some text in there to disguise the link, or you can just paste the link directly. 

TO GET THE LINK: 

Go to spotify.com 
Pick out the song you want to use.
Right click, and select "copy song link" 

Then paste that link in your text box you created!
