Answer:
b, a, c
Explanation:
The middle one has the shortest wavelength, then it's the top one and the last one has the longest wavelength.
Both the object and earth pulls each other towards itself but since the mass and pulling force of objects are very small the pulling force of objects are negligible.
The rank of the capacitors in order of the energy they store is E>A>B>D>C.

What is capacitor?</h3>
In an electric field, a capacitor is a device that stores electrical energy. It has two terminals and is a passive electrical component.
Capacitance refers to a capacitor's effect. While there is some capacitance between any two nearby electrical wires in a circuit, a capacitor is a component made to increase capacitance. The term "condenser" or "condensator" originally applied to the capacitor. Condenser microphones, sometimes known as capacitor microphones, are a remarkable exception to the general lack of usage of this name and its cognates in English.
Practical capacitors come in a wide variety of physical shapes and constructions, and there are numerous varieties that are used often.

The wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.
<h3>What is the speed of wave?</h3>
Speed of wave is the rate by which the wave travels. It can be described as the distance cover by the crest or thrust of it per unit of time. It can be calculated with the following formula,
Here, (f) is the frequency and (λ) is the wavelength.
The frequency is inverse of time. Thus, the value of frequency in time t is,
The speed of the wave is 0.5 m/s. Put the values in the formula,
Thus, the wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.

Hey,
Storage of energy is known as potential energy. If you take a spring for example, and you stretch it then you hold it, it has the energy you put into it but it is potential since it's not moving. Of course once you let go of it its potential energy turns into kinetic energy.
There are other examples as well, such as a battery. I decided to use the spring example because it is simpler.
I hope it helped.
I wrote all that^.
