wht do these lines mean?(physics)?

When the ice was floating on water, the water had lifted by certain level..tht level was equal to the weight of the ice..s when the ice melts , the water level wont increase since the water from icemelt is equal to the earlier weight of the ice ...and the water on which ice was floating had already risen to accomadate tht weight..so it wont rise again when the ice melts...

Electric field lines are a convenient way to sketch an electric field, but in real life, the field is continuous and exists in every direction.\n\nThe lines do not cut each other because they join points of equal field strength, like isobars on a weather map or contour lines on a relief map.\n\nThe lines will never cross because each line represents a specific value, and field strength decreases steadily as you move away from the source.  Crossing lines would mean that there is a point where the field strength is two values at the same time, which is obviously impossible.

here's my guess --\nthat these particles are somehow "connected" . that they do not violate casuality (this one is proveable) or locality....somehow.

I think it is something that placed in a way that from \nright to left (flat way) or so but not from up to down or down to up.\nexample: ------------------------- horizontal line

Well I think they appear as lines; fat, multicolored, curved lines.  But they aren't really "there" where we see them.  That is, other people, say a mile away from you, will see the rainbow shifted from where you see it, and that's because the rainbow's apparent direction is relative to the sun's rays that are near you.  But is this the answer to your question?  Are you asking why they're not thin? straight?  Give us something, Bea.

Sorry, but with the time you spent typing these questions you could of looked them up in your physics book or googled them.  Sometimes getting others to do your leg work isn't always the best answer to a problem.  Good Luck in your new class!

This one has a very interesting answer.\nI am going to try drawing some sketches here. Please bear with me...\n\nAssume that | represents a spoke that is rotating and is currently vertical.\nNext assume that after some time, it goes to position /\nExtending this logic, you see something like this in case of a complete rotation\n| -> / -> -- -> &#92; -> |\n\nNow assume that you take pictures of the whole thing at some interval such that this interval is 3 times slower than what I showed you.\nSo what you would see would be\n| -> &#92; -> -- -> / -> |\nBasically you need to follow 3 arrows and keep cycling around to get to the image.\n\nif you notice, my second case seems to be rotating in the opposite direction of what I had drawn earlier.\n\nThe wheel rotates at some speed. The film is essentially a sequence of still pictures cycled through at some other speed. This difference of speed creates this impression of backwards motion!\n\nHope, I explained it well enough for you!

what does this mean?!

They are the values that make the equation true.  If the equation is true then the equation represents a straight line.

You just got your basic wrong. Try to reveal them again, and understand the ground physics first...\n\nThis webpage may help you to have preliminary understanding...\n\nhttp://computer.howstuffworks.com/hard-disk.htm

They are simply arrows that show the direction a force is applied in (by seeing what direction the arrow points) and how big the force is (magnitude) by how long the arrow is.  So if one vector is twice as long as another, it represents twice the force of the other.

What does C represent?  If C is a constant, then this doesn't converge.\nWhat is the context?  What is the name of the class, chapter and section that this comes from?

It's a string that has a metal weight on one end (a plumb bob). It is hung by the other end, and the weight pulls it down so it makes a vertical reference line. It's used in construction to see that walls and objects are vertical.

For uniform motion:\n\ns/t is a steadily increasing line [straight diagonal across your page]\nv/t is a flat line at a non-zero level [horizontal]\na/t is a flat line at zero [horizontal]\n\nFor uniformly accelerated motion:\n\ns/t is an increasing curve [like the right-hand side of y=x^2]\nv/t is a steadily increasing line [straight diagonal]\na/t is a flat line at a non-zero level [horizontal]
