oil tanker at (0,0) starts to leak oil in a circulat pattern.?

Ooh, calculus... well, maybe.\n\nActually not.  The radius five minutes after is 15meters, right?  So the perimeter is 2πr = 30π\n\nIf the seagull is swimming at (-12, 25) then the radius is determined by the Pythogorean theorem, which is:\n\nr = √(x² + y²) = √(144 + 625) = 27.73 meters\n\nHow long does it take for the radius to get to 27.73 meters?  Divide by 3 ... so about 9.24 minutes.\n\nHere I thought you were asking for the equation of the ship's motion if it's moving steadily in a circular pattern where the radius increases at 3m/minute.  That would have been an interesting problem.

While I was reading the question, my wife asked me to buy 5 liters of kerosene urgently.\n\nI went to the shop; the vendor had kerosene in a barrel; I asked him to empty 5 liter of kerosene from his barrel.  He poured 5 liter of kerosene in my 10 liter can. \n\nHe told that he has emptied 5 liter of air from the can.  I paid him for having emptied 5 liter of air from the can. I also checked whether 5 liter of air is filled up in the vendor’s barrel.\n\nComing home I saw the answer page ¾ empty. To my part I thought to fill the page with some answer. This is the result.

It's an empty metallic cylinder to get samples of water (from the sea). The cylinder is lowered on the water open. When it is at the desired depth, a "messenger" is droped from the ship down the cable. When the messenger impacts the bottle it releases a mechanism that closes the bottle with a sample of water inside.

Because a ship has surface area, a needle doesn't. Water can flow around it, so it sinks.

First guess: Oil (assuming an oil spill) might coat plant surfaces restricting photo synthesis.

Try Reading the END OF OIL by Paul Roberts.\nIt'll run out a darn-sight sooner than we thought!\nOIL companies have/did lie about the amount of oil they have left.\nThe oil that is being pumped now has 2 go thru more refining than ever B4 & is down 2 the amount of Sea water they pump in 2 the fields.\nEverytime a alternative 2 oil is investigated the Oil companies surpress the data.  They R not going 2 give up on oil until every last drop has been extracted & no-one can predict exactly what affect this will have on the Planet. I'm sure that any warnings would proberly supressed by the oil companies 2.

Draw a diagram to represent the positions of the two ships at time t.  This will be a right triangle.  Side A will be the position of ship A and side B will be the position of ship B.  The distance between the ships will be the hypotenuse.  Let's call this S.  By the Pythagorean theorem,\n     S^2 = A^2 + B^2\nDifferentiate with respect to time, t.:\n\n2 S dS/dt = 2 A dA/dt + 2 B dB/dt\n Simplify by dividing the entire equation by 2\n\nS dS/dt = A dA/dt + B dB/dt\nSolve for dS/dt:\n\ndS/dt = 1/S (A dA/dt + B dB/dt)\n\ndA/dt is constant at 24 knots\ndB/dt is constant at 18 knots\n\nAt 5 PM,    A = 30 + 24(5) = 150\n                  B = 18(5) = 90\n                  S = SQRT( A^2 + B^2) = SQRT(150^2 + 90^2)\n                     = 174.9\nTherefore dS/dt = (1/174.9)(150(24) + 90(18)) = 29.8 knots.\n\nIt's just a coincidence that spoonish's answer is about the same as mine.  Only differential calculus can solve this type of problem.

oil. because something ryhmes with oil.

cracked head.  anti freeze is mixing w/ the oil.  Gonna need a new engine.

Either air pressure, or fluid pressure on a fluid present in the cylinder.

I predict complete engine failure. The fuel pump by itself is not going to increase the fuel pressure.

It’s a pressure system, using pressure the gas or oil is moved through the system, that’s why you cant have any leaks, otherwise you lose that pressure, and gas and or oil is pumped through the system properly. Also why you have an “Oil pressure” light or picture etc, on the dash, its moved by pressure, and the loss of pressure can lead to major problems.

It looks like lights hitting water and water dripping on it.\n\nGood album, BTW.

I'm not an engineer, but it would be worth a test. I'm not sure it would have the desired effect, though. Her first five compartments were compromised by either the gash or buckling of steel and popping rivets. Water entering there and allowed to flood evenly would still pull the bow down (although not as sharply) and water would reach the engine rooms and boilers, compromising the pumps even sooner.\n\nThey closed the water tight doors thinking it was the right thing to do. But the watertight compartments only went up to E deck at which point water flooded over their tops to the next compartment. Why didn't they enclose the watertight compartments? Why didn't they have enough lifeboats? Why was the steel so inferior?\n\nA new theory was just presented on Discovery Channel andbased on a recent discovery. They found two intact cross sections of the double-bottomed hull laying in the debris field. These sections traversed the ship from keel hull to keel hull. The theory is that the ship didn't crack as portrayed in the film, but a crack started at the top of the ship and then the ship bowed like a wide U, popping off the bottom hull sections, flooding the engine room, and creating the smashed uppper decks we see on the ocean floor (previously explained as smashed downward during impact with the ocean floor).

It may be surface tension.
