Answer:
i. site.py module
ii. random integer module
Explanation:
i. The exit() function is a function used to end a program in python and can only be called when the site.py module is present. The site.py module comes pre-installed with Python.
<u>So, the site.py module needs to be imported for the exit() function to be invoked.</u>
ii The randint() function is a function used to generate a random integer between two limits- a lower limit and a higher limit. The randint() function can be called when the random integer module is present.
<u>So, the random integer module needs to be imported to invoke the randint() function.</u>
The area of a transverse wave that marks its positive displacement is called the "peak" or the "crest".

Hey! I just did the test and your answer is MAN.
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.
