What is calcium phosphate formula? Ca3(PO4)2 What is phosphate formula? PO₄³⁻ Is phosphate harmful to humans? Although phosphate is not harmful to humans, anthropogenic, or man-made, inputs of phosphorus are well known to have a significant impact on ecosystems, and can damage the health of rivers and lakes (known as eutrophication). What is the chemical […]

What if Earth had no tilt? The tilt of Earth’s axis is the main cause of the seasons. If Earth had no tilt, then the length of daylight and the intensity of solar heating seen by a person standing at a single place on the surface would be the same all year round. What if […]

What are examples of Geosphere? Examples are all the rocks and sand particles from dry land to those found at the bottom of the oceans. They also include the mountains, minerals, lava and molten magma from beneath the earth’s crust. The geosphere undergoes infinite processes constantly and that, in turn, modifies other spheres. What are […]

What is the weird U in physics? Symbols for physical quantities and their international units symbol quantity unit U, UE potential energy, electric potential energy joule V, VE voltage, potential, electric potential volt ℰ electromotive force, emf volt C capacitance farad What is the U shaped symbol? The union symbol ( ) denotes the union […]

What is the use of resonant frequency? Chapter 6 – Resonance One use for resonance is to establish a condition of stable frequency in circuits designed to produce AC signals. Usually, a parallel (tank) circuit is used for this purpose, with the capacitor and inductor directly connected together, exchanging energy between each other. What are […]

Do Snipers have bullet drop in warzone? M82. In another tale of semi-auto sniper rifles being underwhelming, this gun beats the Dragunov thanks to its ability to one-shot headshot in Warzone. There is one area the M82 does excel in though – bullet drop. Despite its slow velocity, your bullets barely fall out of the […]

What are two examples of concave lens? There are many examples of concave lenses in real-life applications. Binoculars and telescopes. Eye Glasses to correct nearsightedness. Cameras. Flashlights. Lasers (CD, DVD players for example). How do we use magnifying lens in our life? Light A magnifying glass (called a hand lens in laboratory contexts) is a […]

What is the significance of Thevenin equivalent circuit? Thevenin’s Theorem is especially useful in analyzing power systems and other circuits where one particular resistor in the circuit (called the “load” resistor) is subject to change, and re-calculation of the circuit is necessary with each trial value of load resistance, to determine voltage across it and […]

Is Haddaway a one hit wonder? For many of us, though, Haddaway is considered a one-hit wonder and the longevity of the song’s popularity can be much credited to the use of the song in Saturday Night Live’s viral skits and subsequent film, A Night at the Roxbury: But Haddaway’s roots lay in his birthplace, […]

Can we sit on a cloud? Although we can’t really touch clouds you could walk through one. In fact that’s what fog is: a cloud that’s formed close to the ground instead of high in the sky. We can’t touch fog but we can move through it. Although it’s fun to imagine sitting on a […]
