Which is the basic unit of matter? In turn, the atom is the fundamental unit of matter…, that is, of an element. The number of positively charged protons and neutral neutrons in an atomic nucleus account for most of the mass of an atom. Each negatively charged electron that orbits a nucleus is about 1/2000th […]

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 […]

Who is credited with creating the first periodic table? British chemist John Newlands was the first to arrange the elements into a periodic table with increasing order of atomic masses. He found that every eight elements had similar properties and called this the law of octaves. How did Moseley establish more accurate periodic table? by […]

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 […]

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 […]

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 […]

What is the real part of 3 2i? 3+ 2i implies the real part to be x = 3 and the imaginary part to be y = 2, respectively. What is 5i equal to? The imaginary number i is equal to the square root of -1. In other words, i2 equals -1. The square root […]

What is the formula of center of mass? The center of mass can be calculated by taking the masses you are trying to find the center of mass between and multiplying them by their positions. Then, you add these together and divide that by the sum of all the individual masses. What is the Centre […]

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 […]

How much below the surface of earth does the acceleration due to gravity reduces to 36%? Since, the acceleration due to gravity decreases by 36% of its value on the surface of the earth. How much below the surface of the earth does the acceleration due to gravity become 10? Answer Expert Verified Let the […]
