Answer:
_type is the correct answer for the above question
Explanation:
- The class variable is a variable that is defined in the class and the instance variable is defined in the constructor of the class using the self keyword.
- The class variable is used as the static variable, but the instance variable is called by the help of objects only.
- The above program holds only one class variable which is "_type" because it is defined in the class.
Answer: A, read the information on the device's packaging
Explanation:
The info in the packaging has to be accurate because it goes through tests and they cannot make up info on there. This means any info about the materials used is accurate.
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.
