Answer:
Wave A.
Explanation:
The energy of a wave is directly proportional to the square of the amplitude.
If a wave has higher amplitude, it will have more energy. On the other hand, a wave having lower amplitude, it will have less eenergy.
In this case, we need to tell which wave has higher energy. Hence, the correct option is A because it has a higher amplitude.

<h2>Answer: electrostatic and gravitational force
</h2><h2 />
Mechanical energy remains constant (conserved) if only <u>conservative forces</u> act on the particles.  
In this sense, the following forces are conservative:  
-Gravitational  
-Elastic
-Electrostatics  
While the Friction Force and the Magnetic Force are not conservative. 
According to this, mechanical energy is conserved in the presence of electrostatic and gravitational forces.
