What are the side lengths of a 30 60 90 Triangle? What is a 30-60-90 Triangle? A 30-60-90 triangle is a special right triangle whose angles are 30º, 60º, and 90º. The triangle is special because its side lengths are always in the ratio of 1: √3:2. How do you find two unknown sides of […]
How long are muscle fibers?
How long are muscle fibers? Muscle fibers are typically large cells, some 20–100 μm in diameter and many centimeters long, with the longest fibers being about 12 cm. These cells are multinucleated, because they need many nuclei to govern protein synthesis and degradation. Does drinking water make muscles look bigger? This surge of fluids causes […]
Why can a magnet attract an Unmagnetized nail?
Why can a magnet attract an Unmagnetized nail? Stroking material containing iron with a magnet, placing a piece of iron in the strong magnetic field, placing a piece of iron near a strong electromagnet. The reason a magnet can attract an unmagnetized nails is that? nails become temporarily magnetized in a magnetic field. Why can’t […]
Is solid light possible?
Is solid light possible? Solid light, often referred to in media as “hard light” or “hard-light”, is a hypothetical material, made of light in a solidified state. It has been theorized that this could exist, and experiments claim to have created solid photonic matter or molecules by inducing strong interaction between photons. Can we produce […]
What happens to kinetic energy when momentum is doubled?
What happens to kinetic energy when momentum is doubled? Kinetic energy is directly proportional to the squared of the velocity. This means that when momentum is doubled, mass remaining constant, velocity is doubled, as a result now kinetic energy becomes four times greater than the original value. Are momentum and kinetic energy the same? They […]
What is the difference between explosion and spontaneous combustion?
What is the difference between explosion and spontaneous combustion? The combustion in which substances suddenly burst into flames, without the application of any apparent cause is called spontaneous combustion. The combustion in which sudden reactions take place on ignition of some substances to produce heat, light, and sound is called explosion. Is combustion spontaneous or […]
How do you make fabric self healing?
How do you make fabric self healing? To obtain the self healing property, materials are dipped into squid teeth proteins, which were turned into a liquid form using yeast and bacteria. This coating process can be applied to a finished garment or to the threads first, before manufacturing. This simple procedure has a large impact […]
Is genetic engineering in demand?
Is genetic engineering in demand? “Today, demand for genetic engineers is rising in India as well as abroad.” After pursuing courses in genetic engineering, you can work in medical and pharmaceutical industries, research and development departments, agricultural sector, genetic engineering firms, chemical companies, etc. Which country is best for genetic engineering? Switzerland, the USA, England […]
Why do electrons move freely in metals?
Why do electrons move freely in metals? The valence electrons of metals move freely in this way because metals have relatively low electronegativity, or attraction to electrons. The positive metal ions form a lattice-like structure held together by all the metallic bonds. When nonmetals bond together, the atoms share valence electrons and do not become […]
Who found atom first?
Who found atom first? Democritus Why can’t scientists see inside an atom? Almost all of an atom’s mass comes from the protons and neutrons in the nucleus. However, because electrons orbit around the nucleus, most of an atom is empty space! You can’t see atoms with the naked eye, because they’re simply too small. Using […]
