Answer: Sound waves are a waves of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
Explanation:
In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid.

The energy carried per photon of light is inversely proportional to the wavelength of the light
The "quantum of electromagnetic radiation" is called a photon. It is, thus, the tiniest and most basic particle of electromagnetic radiation. A photon is a stable particle that has no mass and no electric charge. The concept of wave-particle duality holds true for this particle.
The distance between the two crests or troughs of the light wave is known as the wavelength of light. It is represented by the greek letter lambda 'λ'
A quantity is inversely proportional if it decreases when the related quantity is increased or vice versa. For example, frequency is inversely proportional to wavelength

<h2>Answer: Electric energy
</h2>
Voltaic cells use chemical reactions to generate electrical energy, as well as the reverse process.
This type of cell is mainly composed of the anode (a metal electrode where oxidation occurs) and the cathode (a metal electrode where the reduction occurs). These electrodes are placed in two compartments separated by a porous plate or membrane and immersed in a medium containing ions.
This is how, <u>when the chemical reaction of oxide-reduction occurs, electricity is generated.</u>
Answer:
Please see below as the answers are self-explanatory.
Explanation:
1) The resultant force is along the line that joins both charges or both masses (assuming both objects can be represented as points)
2) Both type of forces obey Newton's 3rd law.
3) Both are proportional to the product of the property that is affected by the force (charges and masses)
4) Both obey an inverse - square law (consequence of our universe being three-dimensional)
1) Main difference, is that while the gravitational force is always attractive, the electrostatic force can be attractive or repulsive, as there are two types of charges, which attract each other being of different type, and repel each other if they are of the same type.
2) It is possible, artificially, to block the influence of the electrostatic force, shielding a room, for instance, which is not possible for the gravitational force.
