How does finding water with that Y shaped object work?

DIVINING ROD [divining rod] or dowser, stick used in searching for underground water or minerals. This form of divination is still in common use in many parts of the world. The instrument is typically a forked twig. The operator holds the forked ends of the twig close to his body, with the stem pointing forward. When he walks over a spot under which water or the desired mineral lies, the stem of the divining rod is supposedly pulled down. Impartial research, however, has indicated that successes in this method result mostly from chance and possibly also from a heightened sensitivity to visual cues of which the diviner is unaware.\n\n\nFor an opposing point of view:\n\nhttp://realmagick.com/articles/93/993.html

you can take a graduated cylinder. fill it with an mount of water to be above object. measure water-write,. now, place object in cylinder. now, record new volume. now, subtract old- new. thi will give you the volume of the irregular object itself. hope this helps!

This is not the sort of thing that can easily be explained online! Find a friend or someone who can give you a short practical lesson.\nThe main things to know are - the scale of the map and what the key means, e.g. blue = water

To do it accurately you may need a PhD. \nOtherwise, build a trough with an uneven bottom.  Then build a ramp to the trough.  On the top of the ramp have a bucket that is constantly being filled with water from a fish tank pump.  Make the bucket so that when it is filled to a certain level it tips and pours down the ramp into the trough.

1) Assuming there are no strong EM fields near the magnet, it should behave exactly as a similar object would due to gravity. The gravitational field of the earth is too weak to produce a measurable effect for this experiment.\n\n2) You need a very long liquid filled container with a speaker on one side and a microphone on the other. Then using a computer to produce and receive the sounds, measure the time taken for the sound to traverse the distance. For accurate results the water needs be still.

You make a container 16 cm by 3 cm (and 1 cm thick) and pour water inside. The weight of the water in gm is your answer.\n\nAnother method is to use Napier's Bones. Just sliding and matching the numbers.

the buoyancy of the object and its volume.

It would make water (H2O).

Water refracts light, which changes the appearance of gthings in it.\nTake a stick, and poke it into a bath of water at a 45 degree angle.\nLook at the stick from an angle, and you will see a serious "kink" in the stick, when you know it is straight.

You're asking about divining.\n\nWhen divining is tested using anything even remotely resembling a scientific test, it fails.  You can't find underwater pipes (tile in your question) or any other form of underground water that way.\n\nYou might resubmit your question to a group that covers perpetual motion, ghosts, or alien abductions.  You might get an explanation from them.

This is same question as "a small stone is dropped from sky". here instead of air there is water, but logic is same. Water resistance plays a major role. Before hitting the floor the pebble achieves the terminal velocity, then moves with constant speed towards the ocean floor. Weight of the stone does not play a role, but shape of the stone does for terminal velocity value. A spherical stone is less resistant that any other shape. [I am assuming it rotates randomly while travelling down, so not considering submarine shape:)].\n\nHow long is still an unanswered question, due to missing data.

D= M/V\n\nIts a formula used to calulated to density (thinkness) of an object by dividing the Mass of an object by its volume. In this case, you can use the water displacement method that displaces (water) from its orignal volume by adding an object (marble). Using a balancer, measure and record the weight of graduated cylinder(ml), before and after the addition of water. Subtract the weight of the cylinder with water from the cyliner's weight and you will get the mass. You have to pay attention to how much the water displacement after adding the marble. record the volumes before and after (if ness). This will solve for volume. Once this is accomplished, you would have no problem finding the density.

if you drop something in the water, it displaces water, and that displaced water moves other water, the rock going down in teh water pushes some up, which then pushes some down, and so on and so on.

The water pressure t a given depth is give as the weight of the water above that depth divided by the area it is being applied.\n\nSo imagine a column of water extending from the top of the lake down the depth.  Calculate the volume of this column of water then using the density of water (1 grams / mL) find the mass.  The take the mass of the water and find its weight (W = mg).  The weight it is the force exerted by the water, but pressure is the force of the water divided by the area it is applied.  So divide the force by the area of the base.\n\nEDIT:\nI see you added the density of water (even though I think my density [1 g/cc] is better).  I will leave you to do your own homework.\n[I also refuse to work with such an ugly unit, I prefer metric]
