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:
Big Data
Explanation:
Big Data refers to data sets that are large, comprising of different varieties (structured and unstructured data types) and which cannot be processed by the day to day database management systems and computer software otherwise referred to as traditional software and techniques.
The term Big does not necessarily refer to a particular size that a dataset must attain but describes the nature of the dataset and the fact that traditional database management systems cannot be used to process them take for example
