dude about that account.... whats the username?

well city has tons of buildings and the buildings have weight. so they will add more pressure to the tectonic plates and cause them to move faster i guess. There are tectonic plates which meet at one point and they either slip, slide or grind agaisnt each other. and when they slip, this causes the earthquake. so then the more weight on the plates means also more pull. so the plates move faster or something. my guess. but i doubt it has any effect

Ok, let's set this straight. Weight is a measure of the force exerted on an object by a gravitational field. It is measured in NEWTONS. Most people are getting this mixed up with mass, which can be measured in metric tons and doesn't change from one gravitational field to another. The weight of the lead on the moon is only 166 Newtons.

KG is a a way to measure a  mass of an object.\nOne (1) kg has been defined by weighing 1 liter of water (10 cm x 10 cm x 10 cm = 1000 cm^3) at room temperature on the surface of the earth. The result was set with the unit : 1 kg. There is no more behind it.\n\nNow what is gravitation ? Every object has a mass and this mass has a force which pulls on other objects. For example the mass of the earth pulls on your mass. The direction is always to the center of the earth .This force can be measured and on the earth surface it is 9.81 m/s^2 (reads meter/square seconds).\n\nWhat you can calculate is the force this creates (in our daily communication we call it "weight") , the formular is:\n\n mass (in kg) x gravitational force (9.81 m/s^2), \n\nin your case it is 50 kgs * 9.81 m/s^2 = 490.5 (kg x m)/s^2. \n\nThis is called a "Newton". Isaac Newton found this law when he was sitting under a tree and an apple fell on his head.\n\nIn the past this force (" weight") was called kilopond and to calculate it you need: \n\n1 Newton = 0.1012 kp , so 490 Newton which figure out to around 49.5 kilopond. (This looks very close to the 50 kgs of the mass and in the past both words were used in the same meaning. For people living on the earth this makes a lot of sense). \n\nWhat you weigh with a weighing machine is not the mass of an object, but the force with which this object is pulled to the surface of the earth and in your case it is around 50 kilopond or 490 Newton.\n\nNow: when you step into an elevator and the elevator accelerates downwards there are two forces: the gravitational force of 9.81 m/s^2 plus the acceleration in the same direction of 2 m/s^2. The key is: they are directed in the same direction.\n\n(A guy called Albert Einstein later found out that gravitation is nothing else than acceleration, but this comes when you study physics and things become a lot more complicated).\n\nBecause they pull in the same direction you can subtract them. In other words the pull of 9.81 m/s2 is reduced by the acceleration of 2 m/s^2 and the result of the subtraction is 7.81 m/s^2.\n\nNow: same calculation as above: \n\n50 kgs * 7.81 m/s^2 = 390.5 Newton = around 39.5 kilopond and which equals 39.5 kilogram (but now you have learned that kg is wrong).\n\nNow: on the moon the gravitational force is smaller than on he earth. The mass of  would be still the same: 50 kgs, but calculated in Newton or kilopond it would be less. You may have seen pictures from astronauts making huuuge jumps because they weigh less than on the earth.\n\nSo the answers to your questions are:\n\nthe weighing machine would read less and the reading would be around 39.5 kgs (in fact it should say kilopond).

By unit volume, probably dry cement is heavier. Why? Because rocks are heavier than water.

The previous answerer has the right idea but the wrong details.\n\nThe four parts should weigh 1, 3, 9 and 27 pounds.  The logic is that the desired weight is written in "balanced ternary" notation, where the values of the digit positions are 1, 3, 9, 27, 81, . . . (that's "ternary"), but the allowed digit values instead of being 0, 1, 2 (that's regular ternary) are -1, 0, 1 (that's balanced ternary).  Then the digit values for any desired total weight written down in balanced ternary tell you whether the weight for that column is to go in one pan, go in the other pan, or stay on the floor.

i have one for you\n"why do they call it building? isn't it already done? y not call it built?"

There is a point at which no structure can withstand an earthquake, but the main ways currently used are:\nA. The building has the ability to flex to some degree.\nB. They are constructed on large rollers or ball bearings.\nC. They are constructed on large hydraulic pistons or springs.\n\nThe Japanese lead in this technology.

hecka!!  damn.  i miss california.\n\nwhat you have to do is realize that this question is asking about the volume of a rectangular shape that is 1 meter by 1 meter by X meters, where X is the height of the column.\n\nso, you know the density.. density is defined as mass divided by volume.  and you know the weight.. which is mass times acceleration.  here the acceleration is the acceleration of gravity "g" = 9.8 m/s^2.  \n\nso you can do a little algebra to get the equation volume = mass / density \nvolume = weight / (acceleration * density)\n\nyou know the weight (100,000 N), the acceleration (9.8 m/s^2) and the density (1.2 kg/m^3).  plug those numbers in and you get the VOLUME of the atmosphere, and since you know 2 of the dimensions of the box (it is 1 square meter across the bottom face, remember) you can figure out the 3rd pretty easily.\n\nsince this is your homework i wont just tell you the answer, but you should be pretty much able to crank it out from here.

Well we need two equatons here:\nF = ma : this will give us the mass\nF = uN : this is just needed\n\nSet these two equal to each other.\nu = .30\nN = 80N\nm = whats needed\na = acceleration due to gravity on earth 9.8m/s^2\n\nThus setting those two equations equal to each other results as follows:\nForce = Force\nuN = ma\n(.3)*(80N) = m * 9.8m/s^2\nm = (.3*80)/9.8\nm = 2.44kg\n\nI have no clue where that above guy created his equation from, but it's sooo wrong.  I mean who weighs items in Newtons.  Newtons is a measure of Force, not weight!

The basic principle behind a Chinese steelyard balance is torque—or leverage, if you prefer.\n\nA symmetrical balance has the two weights equidistant from the point at which they are suspended (let’s call it the “fulcrum,” for simplicity’s sake):  when the weights are equal, the balance levels out.  But let’s say you’re trying to measure the weight of a two-pound object.  Then the balance will level out if you place a two pound weight equidistant from the fulcrum, or a one-pound weight half as far from the fulcrum, or a half-pound weight a quarter of the way from the fulcrum.\n\nThe steelyard balance puts the object to be wieghed at a specific distance from the fulcrum, then moves the known weight along the length of the opposite arm.  The ratio of the distances between the fulcrum gives the ratio of the two weights.\n\nThe link shows the best picture of one that I could find.\n\n\nRyan Wyatt\nRose Center for Earth & Space\nNew York, New York

Three weighings.\nPut 4 on each side and weigh\nTake the 4 from the side that is heavier and \nPut 2 on each side and weigh.\nTake the 2 from the side that is heavier and \nPut 1 on each side and weigh.\nTake the one that is heaver.  It is the heaviest one.

In some areas of the world the tectonic plates press against each other with some amount of pressure. When the pressure grows too great, there is movement in one particular spot, which is then known as the epicenter. A small amount of movement is a small earthquake; a large amount equals a major earthquake.  It is a terrifying experience to be in a major earthquake -- that's why I moved away from Los Angeles.

I live on the island of Lefkas in Greece and we often have earthquakes. The last big one, 7.2 on the Richter scale, was three years ago. There are a few different plates around here under the Ionian sea. As it was August and the height of the tourist season it was fortunate that no one was killed. Except for injuries caused by falling rock and roof tiles we were very lucky. The reason you don't hear about Greek earthquakes is because our houses have to be built to very strict regulations and they don't fall down! No body bags, no news as far as the press is concerned. Thank goodness.
