What is the most important function of stratospheric ozone? Stratospheric ozone is a naturally-occurring gas that filters the sun’s ultraviolet (UV) radiation. This is typically regarded as ‘good’ ozone since it reduces the harmful effects of ultraviolet (UV-B) radiation. A diminished ozone layer allows more radiation to reach the Earth’s surface. Why is o3 unstable? […]

What electron microscopes are used for?
What electron microscopes are used for? Electron microscopy (EM) is a technique for obtaining high resolution images of biological and non-biological specimens. It is used in biomedical research to investigate the detailed structure of tissues, cells, organelles and macromolecular complexes. How do electron microscopes help us? The development of the electron microscopes therefore helped scientists […]
What is the purpose of inductor in a circuit?
What is the purpose of inductor in a circuit? An inductor is a passive electronic component which is capable of storing electrical energy in the form of magnetic energy. Basically, it uses a conductor that is wound into a coil, and when electricity flows into the coil from the left to the right, this will […]

Why do ships float Archimedes Principle?
Why do ships float Archimedes Principle? Why the Ship Floats Archimedes’ buoyancy principle states that buoyant force — what keeps the ship afloat — is equal to the weight of water that is displaced when the ship enters the ocean. If the weight of displaced water is at least equal to the weight of the […]
