It is always found bonded with other elements, it goes through a process to become a single element.
This is not a straightforward question. It's not too hard to develop an Excel spreadsheet parameterized by the width and length of the space to be covered, and the height of the roof, but there are other significant elements like the thickness of the lamella and the nature of the connectors. The basic idea is that each lamella arch is circular in section, with an integral number of lamellas, skewed with respect to the orientation of the space. Then each of the, say, n lamellas subtends an angle equal to 1/n of the angle subtended by the whole arch, so its unadjusted length is easy to calculate.
Proteins are found in all living things as well as needed by living things. Animals and vegetables are good sources of protein.
grms is not a unit of expressing vibration and thus this is not a valid question. Random vibration is that field of study where the input load to a mechanical system is not deterministic in nature, so we need to analyse it in a probabilistic sesnse. In many situation this may serve the purpose as in many cases we are interested in the peak values of the response and the filed of random vibration enable tackling this in terms of knowing the excitation from the probabilistic sense, i.e. through the knowledge of mean, varience etc.
A bit is an atomic unit in computing. As such, it is the smallest numeric unit in computing, but since a bit is an abstract concept rather than a physical entity, it has no size or dimension as such. The key characteristic of a bit is its atomic nature. Unlike real atoms, it cannot be split into parts. (Note, however, that some encodings transmit multiple symbols to describe a single bit of information. The popular Manchester encoding is an example for such an encoding scheme. However, this does not mean that a bit is subdivided into smaller parts when transmitted with this encoding; a single bit remains indivisible even when represented by multiple symbols.)
Engineered materials can differ from natural materials in many ways. Engineered ones are made for specific purposes, some to have more tensile strenght like steel and kevlar, others to be more ductil like the elastomers, others to resist to higher temperatures like the ceramics on the space shuttle, others to conduct electricity like silicon based transistors, and so on. They also differ on composition. Engineered materials can be a mix of natural materials (and by this i mean that occur in the nature without human intervention) and man-made, or only man-made materials.
Many elements are found in nature in molecular form - two or more atoms (of the same type of element) are bonded together. Oxygen, for example, is most commonly found in its molecular form "O2" (two oxygen atoms chemically bonded together).
Very few elements exist in their free state in nature. The vast majority of them exist as compounds, chemically bonded to other elements.
magnesium :)
i thought all elements are found in nature, only some need to be specifically extracted to become lone, and not bonded with other elements. there are very few atoms that are found lone and singular, and most need man-made machinery to extract it.
Alkali metals are not found as pure elements in nature.
Discover Elements have always existed, in nature
Group 3 elements
Absolutely not. The vast majority are found in a combined state in nature. Iron is not found as metal but always as an ore of mixed oxides etc. The halogens and all group 1,2,3 metals are always found combined etc.
'cause I'm always where I need to be Yeah, and I always thought I would end up With you, eventually Do dodo do do do do...
Two or more different elements that are chemically combined in a definite ratio is a compound. Based on the nature of the bonds, it can be called an ionic compound (i.e. atoms bonded together by ionic bonds) or an molecular compound (i.e. atoms bonded together by covalent bonds).
the nature is broadest sense in physical nature and the elements is verbal vocal visual
In the atmosphere and, bonded with oxygen, in quartz.
