What is it?10 points for best answer :3
mutually as your question is worded in a perplexing way, i'm going to purpose perfect to describeGravity quickens any mass down in direction of the middle of the Earthit particularly is likewise represented as a rigidity, as F massacceleration mg An merchandise sitting on the floor won't circulate down, besides the shown fact that gravity nonetheless acts upon itas a effect, to counteract the rigidity of gravity (that's needed for an equilibrium static difficulty wherein the chair isn't shifting), it particularly is reported that there is an equivalent and opposite rigidity that pushes up on the chair to counteract the rigidity of gravityThis rigidity could be offered by potential of the floor the chair is sitting onin an identical way, in case you have been sitting on the chair, you may adventure the two a rigidity downward as a results of gravity, yet in addition a rigidity upward from the chairas a effect, the two forces cancel out as they are in opposite guidelines, and you do no longer circulate up or down.
all you need is the equation work force distanceso, for example, in 1, work is 4020 800 J.
1) Work Force distance (if the force and distance are alligned) 2) work weight rise 3) work force (10N) how far the brick wall wentThis question is an idiot-checkIf you pull out your calculator, you fail the check4) risk work / weight You can plug in the numbers.
ok, i only have the answer for 1,2,4 but hope it helpswork done (J) Energy Transferred (J) work done (J) force applied (N) x distance moved in direction of force (m) 1800 J 2100 N 3(don't have the answer, sorry) 412 meters p.sthanks for asking this cos it's a great help for me as I'm doing some revision for my GCSE Science exam next month and i have to practice work done etc.
Porcelain is a ceramic material made by heating raw materials, generally including clay in the form of kaolin, in a kiln to temperatures between 1,200 °C (2,192 °F) and 1,400 °C (2,552 °F)The toughness, strength, and translucence of porcelain arise mainly from the formation of glass and the mineral mullite within the fired body at these high temperaturesPorcelain derives its present name from old Italian porcellana (cowrie shell) because of its resemblance to the translucent surface of the shellPorcelain can informally be referred to as china in some English-speaking countries, as China was the birthplace of porcelain makingProperties associated with porcelain include low permeability and elasticity; considerable strength, hardness, toughness, whiteness, translucency and resonance; and a high resistance to chemical attack and thermal shockFor the purposes of trade, the Combined Nomenclature of the European Communities defines porcelain as being completely vitrified, hard, impermeable (even before glazing), white or artificially colored, translucent (except when of considerable thickness) and resonantHowever, the term porcelain lacks a universal definition and has been applied in a very unsystematic fashion to substances of diverse kinds which have only certain surface-qualities in common (Burton 1906).
