Answer:Protons, neutrons, and electrons are the three main subatomic particles found in an atom. Protons have a positive (+) charge. An easy way to remember this is to remember that both proton and positive start with the letter "P." Neutrons have no electrical charge.
It is force because work/distance= force
The last equation gives you the tension in the string on the right:
Answer:
<em>Micro waves and radio waves are electromagnetic </em><em>waves while </em><em>ocean wave and seismic wave are mechanical waves. </em>
Explanation:
Electromagnetic waves do not require a medium for propagation. They can travel along vacuum just like they travel through matter.
Further examples of electromagnetic waves are x rays, infrared waves etc.
Spectrum of electromagnetic waves in the increasing order of frequency is radio waves, microwaves, infrared waves, visible light, ultraviolet, x ray, gamma ray.
Mechanical waves require a medium for propagation. Thus they cannot travel through a vacuum.
Sound wave is an example of mechanical wave.
