Answer:
Explanation:
Given
Mass of mother 
Mother is released with a speed of 
Assuming we need to find elastic Potential energy stored in Trampoline
Kinetic energy acquired by Mother comes from Elastic Potential Energy stored in the spring
I.e. Elastic Potential Energy=Kinetic Energy of mother

So 246.875 J of Energy is stored in the trampoline as he pull the ring

<h2>Answer: Radio waves </h2><h2 />
Radio waves are a type of electromagnetic radiation with wavelengths between 10 m to 10,000 m. In the electromagnetic spectrum this wavelength is longer than infrared light and therefore, it goes beyond the visible spectrum.
This type of electromagnetic waves is very well reflected in the ionosphere, the layer of the atmosphere through which they travel directly or using repeaters.
In addition, they are very useful to transport information, being important in telecommunications. They are used not only for conventional radio transmissions but also in mobile telephony and TV.
It should be noted that since radio signals have large wavelengths, they can be diffracted around certain obstacles, such as hills and mountain ranges, preventing the signal from reaching its destination.
Therefore, the correct option is C.
