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:
Macintosh.
Explanation:
Macintosh refers to a set of computers designed, developed and manufactured by Apple Inc. Apple officially began the sales of Macintosh on the 24th of January, 1984. The first designs of Macintosh are considered to be personal computers and had a mouse, in-built screen with a graphical user interface (GUI).
Macintosh developed the first design technology program which had a mouse and allowed for photo manipulation. This technology or software program used for photo manipulation is known as MacPaint, it was a raster graphics editor which was originally coded by Bill Atkinson using a Pascal programming language while its graphical user interface was designed by Susan Kare.
Front-end the part with which the user interacts.
usually people who write this are called layout designers what languages are used (Html, css, js)
Beck-end The northern part is the structure of the site due to which it works, this includes the DBMS, logic, etc. which languages will be used(python, php, java)
People who can do both are called: full stack developr
