What are action and reaction pairs? According to Newton’s third law, for every action force there is an equal (in size) and opposite (in direction) reaction force. Together, these two forces exerted upon two different objects form the action-reaction force pair. Is normal force an example of Newton’s third law? This force is applied by […]
What is the function of auditory nerve?
What is the function of auditory nerve? The cochlear nerve, also known as the acoustic nerve, is the sensory nerve that transfers auditory information from the cochlea (auditory area of the inner ear) to the brain. It is one of the many pieces that make up the auditory system, which enables effective hearing. Where is […]
What does the tectonic plates do?
What does the tectonic plates do? The theory of plate tectonics states that the Earth’s solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet. Where does New […]

What are the 3 factors that affect the speed and travel of sound? The factors on which the speed the sound majorly depends are: The Density of Medium: Sound requires a medium to travel. The density of the medium is among the factors which affect the speed of sound. The Temperature of The Medium: Higher […]
Why stones are strong in compression but weak in tension?
Why stones are strong in compression but weak in tension? Answer: Because it has essentially zero strength in tension, it is almost always used as reinforced concrete, a composite material. It is a mixture of sand, aggregate, cement and water. Is steel better in compression or tension? Steel is equally strong in tension and compression. […]
