How deep can you dig into the earth? 40,230ft What happens if you dig too deep in the earth? To make things more difficult, as they drill deeper into the Earth, they’ll encounter extreme temperatures, possibly in excess of 1,000 degrees Fahrenheit (538 degrees Celsius), and fantastic amounts of pressure — as much as 4 […]

What is better active or passive noise cancellation? While both passive noise isolation and active noise cancellation allow you to listen to music at lower volumes than earphones without ANC, passive noise isolation is better for your hearing overall. This is because active noise cancellation neutralizes outside noise by creating an equal and opposite noise. […]

What is the Centre of pressure on an aerofoil? Center of Pressure The center of pressure is the point where the total sum of a pressure field acts on a body. In aerospace, this is the point on the airfoil (or wing) where the resultant vector (of lift and drag) acts. What happens to the […]

What is lithium-7 used for? Li-7 is used to control the pH level of the coolant in the primary water circuit of pressurized water reactors. Li-7 is also used for the production of the medical research radioisotope Be-7. Li-6 is used in thermonuclear weapons and the export and use of Li-6 is therefore strictly controlled. […]
