Answer: The radio should be tuned to 100. 0 Mhz.
Explanation:
As radio waves are electromagnetic waves, like x-rays, UV rays, and all the wavelengths of visible light, they propagate in the free space at the speed of light: 3. 10⁸ m/s.
At any wave, there is a fixed relationship between the distance travelled by the wave along one cycle (which is called wavelength ) and the speed at which the wave oscillates (which is called the frequency of the wave), with the speed at which the wave propagates, as follows:
λ (wavelength) = v (speed) / f (frequency)
Replacing by the values, and solving for frequency, we have:
f = 3. 10⁸ m/seg / 3 m = 10⁸ 1/sec = 10⁸ Hz = 100. 0 Mhz
This is the radio channel to which must be tuned in order to listen the station with a wavelength of 3 m, in the FM band.
Answer:
D)One big superclass can be used instead of many little classes.
Explanation:
Inheritance could be described as getting new class on another existing class with almost same execution,
inheritance allows codes to be re-used. It should be noted that inheritance bring about the code sharing among class.
The advantages of using inheritance includes but not limited to
✓ Code that is shared between classes needs to be written only once.
✓Similar classes can be made to behave consistently.
✓ Enhancements to a base class will automatically be applied to derived classes.

<h3>What is
Setup?</h3>
Setup is the arrangement of something, or a competition when the winner is already known because the two competitors are not evenly matched. The setup of food and beverages at a party is an illustration of a setup. A setup might involve pairing a strong debater with a weak debater.
Whether we like it or not, US English spellings have a significant influence on a lot of our language today. Therefore, the phrase "setup" is used when discussing the start of computer programs, but in all other contexts, the words "to set up" and "the set-up" are used instead.
Informal. an endeavor or competition that is made purposefully simple. a game or contest where the opponent can be easily defeated without risk or effort.

Answer:
1. When an object of the class is passed (to a function) by value as an argument.
2. When an object is constructed based on another object of the same class.
3. When compiler generates a temporary object.
Explanation:
Most importantly, musicians can share their works with others. Other people can see their musical ideas and can try and perform them too. Nuances such as tempo, dynamics (loud soft, sweet, "harsh", are just some examples) can be understood even if the composer is not present and there is no recording to listen to.
Financial benefits can be realized from the sale of sheet music, scoring the piece, arranging the piece for bands, orchestras, etc. Conductors can lead an entire musical ensemble through the piece.
