Answer to:
why sea water at deep ocean doesn't turn to ice? ( considering low temperature and very high pressure) density of water .... the density of water increases down to near freezing and thus cold water sinks .. to a point ... just before the freeze point the density of water decreases (starting of a phase change) making it rise..... thus the only water to freeze will be at the top

Answer to:
Can a 10 amp primary transformer input voltage of 220vac step to 40 amps in the secondary and still output 220 vac, are there such devices No... you would be taking more power out than putting in... remember PIE.. power = I (current) x E (voltage)

Answer to:
If an electric motor is 230v with 20 amp on the name plate does that mean the moment i hook it up it is drawing 20 amps without a load on it No.. It just means the motor is designed to run at a full load of 20 amps... its still possible to run over or under those amps basedd on actual motor load... but it should be able to run at 20 amps continuously without overheating or damage

Answer to:
from my info; in a circuit,volt. is needed to provide current.So what is the difference between voltage-source and current-source circuits? example .. in industry you may have a transmitter that varies the output voltage as say the pressure increases on the transmitter. thus it is ranged in voltage... but it is more common for the transmitter to output more current as the pressure increases. thus one transmitter is say 4-20 milliamp and the other is say 0-3 volts

Answer to:
why sea water at deep ocean doesn't turn to ice? ( considering low temperature and very high pressure) dewshaft answered it but maybe not obvious.... water gets denser (and thus sinks)until it gets near freezing .. then (due to crystization) it gets less dense and rises. thus water on the ocean floor will never freeze until the it freezes from the top down... thus water at great depths is not cold enough to freeze water especially salt water.

What is the difference between a concrete driveway & an asphalt driveway? Specifically, how do I tell them apart from each other? Asphalt driveway is a roll mass of small rock in asphalt ( a black tar). It is layed hot and rolled after which it cools and hardens. Even though it hardens it never gets as hard as concrete. This allows it to be elastic enough to adapt to the contour beneath it. However it is not as strong as concrete. Concrete is made by mixing agregate (rock, sand, pebbles etc) in calcium oxide powder...

Answer to:
How could the thermal efficiency decrease, if the pressure of the steam entering the boiler increased in nonideal rankine cycle? In a simple way the increase in steam pressure leads to an increase in temperature of the steam/water in the boiler system. As this temperature goes up ... the difference in temperature between the combustion gasses and the steam system decreases. thus less heat is transfered ... This leads to a greater stack loss less efficient system....

Answer to:
why does ice melt faster in water than oil The simple answer is that heat transfer of ice sitting in a bath of oil verses water ... the difference in the heat transfer rates is due to the difference in conductive heat transfer of the two fluids surrounding the ice .. the thermal conductivity of oils (~0.16 watt/degK-M) is lower than that for water (~0.6 watt/degK-M). Thus the heat is carried away by the ice more quickly in water... ...

Now Na3N require 3 Na for each N therefore Na is the limitng reactant since 0.609/3 = 0.203 mole of Na3N possible at 100 % conversion ... thus yeilds in molar % = 0.136/0.203 = 67%

Cooling towers .. water temperature will run about 10 degF below ambiet air running through the tower... The dew will form due to a surface effect and as it evaporates it further cools thereby freezing under the proper...

Turn on a faucet at one location the pressure drops at the other... Same applies for electric... the wires at a given voltage can only pass so much current.... Is there a danger... not really .. the circuit breaker or fuse will prevent too much current flow preventing the voltage from dropping ridiculously low...

Last night i woke up to a warm house,went to check the a/c and the fan was not blowing.I turned it off and and stuck a knife in the fan and gave it a push and it started working,what would cause it to stop again? The problem is the capacitor... its purpose is to kick start the motor in the proper direction .. if it goes bad no kick .. ie no motor start ... but even worse.. if it goes partly bad it reduces the voltage to the motor and motor runs with higher amps gets hot and kicks out on the motor thermal protection ... Capacitors cost about $25 .. much less than the motors

Find the two numbers Captain gave the correct answer ... but here's how you approach the problem with algebra.... x + y = 56 and x - y = 4 two equations two unknowns a solveable system... x-y=4 solving for x gives x = y + 4 substite in the second equation x + y = 56 gives (y+4)+ y = 56 or 2y + 4 = 56 subtract 4 from both sides gives 2y = 52 divide both sides by 2 gives y=26 solving for x ... x + y =...

Answer to:
The hotel charges before tax in the 2nd city were $1000 lower than the 1st.The tax on the hotel bill was 7.5% in 1st city & 6% in the 2nd. After the trip, total tax paid on accommodation expenses was $750.How much was the bill for the 1st city before tax? x= bill in 1st city before tax y= bill in 2nd city before tax 1st statement .. x-1000=y 2nd & 3rd statements 0.075x + 0.06y = $750 ... so two equations two unknowns solve... easiest to sub for y of the first expression into the second .. 0.075x + 0.06(x-1000)= 750 ..solving gives 0.135x - 60 = 750 .. gives 0.135x=690 .. gives x=$5,111.11

Answer to:
In a box there are 4 chocolate bars, 3 gums and two mints. What is the probability that you pick a chocolate bar and a gum? I know I need to use the P(A) = n(A) / n(S) formula, and I'm pretty sure that the n(S) is equal to 9P2. I just don't know n(A). Eltinwe gave a correct answer but to your notation... yes for the first selection (the chocolate bars) n(A)=4, n(S)=9 so the P(a)= 4/9 ... the second event picking a gum after one item has been removed is n(a)= 3, n(s)=8 or P(a)= 3/8 .. so the probability of both happening is the product .. 3/8 x 4/9 = 1/6

Use the given conditions to write an equation for the line in the indicated form.. The Problem is : Passing through (4,5) and parallel to the line whose equation is y=2x-6; point-slope form... "anybody understand this?" Parrallel lines have the same slope... linear equations have the form y=mX+b where m is the slope... in this case the given line has a slope of 2 so your new line has a slope of 2... so y=2x+b so now find b by substitution of the point you do know... (4,5) ie (x,y) thus 5=2(4)+b 5=8+b b=-3 so you new line is y=2x + -3 or y=2x-3

If wire is large enough, the rise in temperature is very small. If wire is smaller (for the same amount of electricity flow) it will get hotter. If you try to send more current down the wire it gets hotter. So when they wire a house they place a size wire in a circuit and protects that size wire with a fuse or circuit...
