What is the atomic mass of Mg2+? 24.305 g/mol What is the atomic number of Mg2 +? 12 Why is magnesium ion Mg2+? Magnesium, Mg It has two electrons in its outer shell. When these electrons are lost, a magnesium ion, Mg 2+, is formed. A magnesium ion has the same electronic structure as a […]
Where should the receiver be placed to maximize reception?
Where should the receiver be placed to maximize reception? The receiver of the satellite dish is placed at the focus of the parabola, to maximize signal reception. How many inches should the receiver be located from the vertex for optimal reception? 10.126 inches How do you measure the depth of a parabolic dish? Step 1: […]
What is a trefoil symbol?
What is a trefoil symbol? A trefoil (from the Latin trifolium, “three-leaved plant”) is a graphic form composed of the outline of three overlapping rings, used in architecture and Christian symbolism, among other areas. The term is also applied to other symbols with a threefold shape. A similar shape with four rings is called a […]
Does the sign of the acceleration alone tell you whether an object is speeding up or slowing down?
Does the sign of the acceleration alone tell you whether an object is speeding up or slowing down? Another way to say this is that if the acceleration has the same sign as the velocity, the object will be speeding up. And if the acceleration has the opposite sign as the velocity, the object will […]
What is the mass number and charge of the emitted positron?
What is the purpose of dark matter?
What is the purpose of dark matter? [+] Dark matter is the most mysterious, non-interacting substance in the Universe. Its gravitational effects are necessary to explain the rotation of galaxies, the motions of clusters, and the largest scale-structure in the entire Universe. Can we see dark matter? Although we cannot see dark matter and we […]
What frequencies are dangerous?
What frequencies are dangerous? The most restrictive limits on whole-body exposure are in the frequency range of 30-300 MHz where the RF energy is absorbed most efficiently when the whole body is exposed. For devices that only expose part of the body, such as mobile phones, different exposure limits are specified. What is the range […]
How important is the lithosphere?
How important is the lithosphere? The lithosphere is largely important because it is the area that the biosphere (the living things on earth) inhabit and live upon. When the biosphere interacts with the lithosphere, organic compounds can become buried in the crust, and dug up as oil, coal or natural gas that we can use […]
How much power does a 5kW solar system produce per day?
How much power does a 5kW solar system produce per day? 5kW Solar System Details: Produces 5,000 watts of DC (direct current) power. Requires up to 400 square feet of space to produce an estimated 350 to 850 kWh (kilowatt hours) of AC (alternating current) power monthly. Is 5 kW solar enough? On average, a […]
What are the characteristics of deposition?
What are the characteristics of deposition? Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment. Which landform is […]
