state and proof hook's law. |
| Answer» <p>Hooke's Law is a scientific law concerning itself with the elasticity of materials. It states that when a force is applied to a material, the displacement of that material will be directly proportional to the force applied. Hooke's Law applies, so long as the material is within it's elastic limit.</p> <p>Hooke's law states that the strain (ε) induced in the material is directly proportional to the stress applied (σ) in the elastic regime of the material.</p> <p>proof?</p> | |

describe soluble in water. with example |
| Answer» <p>Why Do Some Solids Dissolve in Water?</p><p>The sugar we use to sweeten coffee or tea is amolecular solid, in which the individual molecules are held together by relatively weak intermolecular forces. When sugar dissolves in water, the weak bonds between the individual sucrose molecules are broken, and these C12H22O11molecules are released into solution.</p><p>It takes energy to break the bonds between the C12H22O11molecules in sucrose. It also takes energy to break the hydrogen bonds in water that must be disrupted to insert one of these sucrose molecules into solution. Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules. The weak bonds that form between the solute and the solvent compensate for the energy needed to disrupt the structure of both the pure solute and the solvent. In the case of sugar and water, this process works so well that up to 1800 grams of sucrose can dissolve in a liter of water.</p><p>Ionic solids(or salts) contain positive and negative ions, which are held together by the strong force of attraction between particles with opposite charges. When one of these solids dissolves in water, the ions that form the solid are released into solution, where they become associated with the polar solvent molecules.</p><p>H2ONaCl(s) Na+(aq)+Cl-(aq)</p><p>We can generally assume that salts dissociate into their ions when they dissolve in water. Ionic compounds dissolve in water if the energy given off when the ions interact with water molecules compensates for the energy needed to break the ionic bonds in the solid and the energy required to separate the water molecules so that the ions can be inserted into solution.</p> <p>Sugar and salt areexamplesofsolublesubstances. Substances that do notdissolve in waterare calledinsoluble. Sand and flour areexamplesofinsolublesubstances.</p> <p>The solvent is often a solid, which can be a pure substance or a mixture. The species thatdissolves, the solute, can be a gas, another liquid, or a solid. Solubilities range widely, from infinitelysolublesuch as ethanol inwater, to poorlysoluble, such as silver chloride inwater.</p> <p>Thingslike salt, sugar and coffeedissolve in water. They aresoluble. They usuallydissolvefaster and better in warm or hotwater. Pepper and sand areinsoluble, they will notdissolveeven in hotwater.</p> <p> substances that dissolve with water called souble salt and sugar </p> <p>soluble that dissolves with water called solublesalt and sugar</p> <p>substance that dissolve with water called soublesalt and sugar</p> <p>anything tha dissolve in water is called soluble in water...</p> | |

Ques -Answer each in a few words onl(a)-Name any three products prepared from milk(b)-Name the fat soluble vita.ins?(c)-The process of making cotton?(d)-A long strand made of fiber? |
| Answer» <p>a. Dairy product, milk and any of the foods made from milk, including butter, cheese, ice cream, yogurt, and condensed and dried milk.</p> <p>b. Fat-soluble vitamins: A, D, E, and K — are stored in the body for long periods of time, and pose a greater risk for toxicity than water-soluble vitamins. ...</p> <p>c. From field to fabric, the process of making cotton transforms the raw fibers into threads, yarn and fabric in three steps: Preparation, Spinning, and Weaving.</p><p> </p><p> In America, this process was a tedious, labor-intensive activity done by hand until the 19th century. For most colonists, they either made their own homespun from cotton, linen, or wool or they purchased fabric imported from England. With the development of modern technology, the process of making cotton is complete in a fraction of the time.</p><p>PreparationTo be used for thread or fabric, raw seed cotton must cleaned and free of debris. Seeds, burrs, dirt, stems and leaf material are removed from the cotton during ginning.</p><p>Unginned and ginned cottonUnginned and ginned cottonInvented by Eli Whitney in 1794, the cotton gin was one of the many inventions that was created during the American Industrial Revolution.</p><p>Module feeders break the modules apart and feed the cotton into the gin.</p><p>Some module feeders have giant conveyors moving the modules into stationary heads.</p><p>Other module feeders are self-propelled, moving down a track alongside the modules.</p><p>Cotton modules at the ginCotton modules at the ginOnce in the cotton gin, the seed cotton moves through dryers and through multiple cleaning machines that remove the gin waste such as burrs, dirt, stems and leaf material from the cotton. Once thoroughly clean and dry, the cotton goes to the gin stand where circular saws with small, sharp teeth pluck the fiber from the seed. This process makes the sliver smoother so more uniform yarns can be produced. Then the cotton is packed tightly into bales, ready to be processed into textiles.</p><p>Even though the cotton is cleaned during the ginning process, it's not nearly as clean as it needs to be. Cotton fibers are shaved from the bales and sent through a series of cleaning and drying machines. The mixed and fluffed-up cotton goes into a carding machine which finishes the cleaning and straightening of the fibers, making them into a soft, untwisted rope called a sliver (pronounced sly-ver).</p><p>The sliver is drawn out to a thinner strand and given a slight twist to improve strength, then wound on bobbins (spools wound with the thread-like product for storage). </p><p>It is now called roving and the roving bobbins are now ready for the spinning process.</p><p>SpinningOn modern spinning frames, yarn is mare directly from the sliver. The spinning devices take fibers from the sliver and rotate it up to 2,500 revolutions in a second twist that makes fibers into a yarn for weaving or knitting into fabrics.</p><p>Spinning is the last process in yarn manufacturing. Today's mills draw and twist the roving into yarn and place it on bobbins. They do this quite efficiently. A large, modern mill can produce enough yarn or thread in 30 days to wrap around the earth 2300 times or go to and return from the moon 235 times. With the use of automatic winding, the yarn bobbins are transferred to larger bobbins called cheese cones. These cheese cones can be stored until they are needed in the weaving process.</p><p>WeavingLooms weave cotton yarns into fabrics the same way the first hand-weaving frames did. Modern looms work at great speeds, interlacing the length-wise yarns (warp) and the crosswise yarns (weft).</p><p>Warp refers to yarns that run lengthwise in woven goods. In preparation of warp yarns for weaving, hundreds of yarn strands are wound from cheese cones onto a large warp beam. Yarns on this beam are then coated with a starch mixture (sizing compound) to add strength for weaving. </p><p>Cotton weave -- warp and weft yarnsCotton weave -- warp and weft yarnsWeft is the yarn that runs crosswise in woven goods and may be referred to as filling yarn. Sizing is not placed on weft because flexibility is needed in the weaving process.</p><p>In today's most modern mills, the weft is fed into the loom from cheese cones with air-jets at such a high speed that its movement cannot be seen.</p><p>The woven fabric, called gray goods, is sent to a finishing plant where it is bleached, pre-shrunk, dyed, printed and given a special finish before being made into clothing or products for the home. Other machines make knits for use in shirts, sweaters or blankets.</p> <p>d. Each strand is, in turn, made of fibers, all shorter than the piece of yarn that they form. These short fibers are spun into longer filaments to make the yarn. Long continuous strands may only require additional twisting to make them into yarns. Sometimes they are put through an additional process called texturing.</p> <p>#CutCut#CutCut#CutCut</p> <p>rice is a major food in sathern part of India</p> | |
