Which metal does Duralumin not contain? Such sheets are called alclad, and are widely used by the aviation industry. Hence, we can say that duralumin contains copper (Cu), magnesium ( Mg) and manganese (Mn) but does not contain sodium (Na). Therefore, the correct answer is choice (D). What are the composition of duralumin write its […]

How do you solve simple equations? Addition and subtraction equations Example 1. Solve for x. x + 8 = 12. To solve the equation x + 8 = 12, you must get x by itself on one side. Example 2. Solve for y. y – 9 = 25. To solve this equation, you must get […]

Where are the strongest winds and heaviest rains in a hurricane located? All hurricanes begin life in a warm moist atmosphere over tropical ocean waters. A typical hurricane can dump 6 inches to a foot of rain across a region. The most violent winds and heaviest rains take place in the eye wall, the ring […]

What is the relationship among DNA a gene and a chromosome Mcq? A chromosome contains hundreds of genes, which are composed of protein. C) A gene contains hundreds of chromosomes, which are composed of protein. D) A gene is composed of DNA, but there is no relationship to a chromosome. How is a chromosome related […]

What do you do if you touch a halogen bulb? If you do touch the bulb accidentally, it’s best to clean it thoroughly with rubbing alcohol, as water alone will not remove all of the oils. Can I replace MR11 halogen with LED? I’ve seen MR16 LED retrofit lamps, are LED lamps also available to […]

What is the fastest way to freeze water? Rock salt lowers the freezing/melting point of ice, thus the water inside the water bottle/bottles gets a so called ‘boost’ and the water freezes faster than it’s usual time. Another method is by using liquid nitrogen. This can freeze water almost instantly. How do I get ice […]

What created the Great Pacific Garbage Patch? The Garbage Patch is created by the North Pacific Gyre. A Gyre is a system of circulating currents in an ocean, caused by the Coriolis Effect. Over time gyres can spit out debris that accumulates in them and an example of that can be seen on beaches in […]

What can be dated using carbon-14? Over time, carbon-14 decays in predictable ways. And with the help of radiocarbon dating, researchers can use that decay as a kind of clock that allows them to peer into the past and determine absolute dates for everything from wood to food, pollen, poop, and even dead animals and […]

Which element is a member of the halogen family *? Answer and Explanation: The halogens are a group of 5 elements: fluorine (F), b. chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The halogens are so-called because they generate (the suffix -gen) sodium salts (hal- means salt in Greek) with similar chemical properties. Which […]

What is radiometric used for? The radiometric, or gamma-ray spectrometric method is a geophysical process used to estimate concentrations of the radioelements potassium, uranium and thorium by measuring the gamma-rays which the radioactive isotopes of these elements emit during radioactive decay. What is radiometric dating used for quizlet? The process of using the concentrations of […]
