TRIVIA QUESTION !!! Need your help !

[wml]

Ok guys, my co-workers and myself are in a discussion about a question my Luietenant asked earlier today, and we have got alot of mixed answers. Here's the question !

You have a contanier that say has 20 lbs. of water in it, and you you drop a 5 lbs. Bass in the contanier, DOES the container way 25 lbs. now ?????  Remember the Bass will suspend in the water so what do ya'll think ????? we have not come to a answer for this yet.

[bkoguy07]

Well technically weight = mass times gravity... so w=mg

so the (mass of water + mass of fish + mass of container)g = Total weight.

(Mass of water+mass of container)g=weight without fish

1st>2nd... just cuz its suspending doesn't mean its weight isnt accountable.

[WRB]

The container will not equal the sum of the 2 weights. The reason is the bass is hollow, has a bladder filled with gas, making the bass bouyant, weighing less in the water than out of the water.

But the fish is still 5 lbs. of mass in the water and out right ???  I don't know it's got me confused, I am sure someone has a scientific answer to this ?????  or a logical country boy terms answer ????

[Aaron]

lbs. is not a measurement of mass.  mass is measured in g, kg, etc.

Weight (lbs) is a force.

I think the container + fish + water would be 25 lbs.  Isn't that how tourny weigh-ins are done?  Container of known weight plus fish equals new wieght.  New weight minus known container weight equals fish weight.

This sounded good in my head, don't know how it will come out on screen :-?

Think about this.....

Don't the FLW guys do their weigh-ins in a tank????

I know that, just do a little unit conversion...

[AnthonyRSS]

It will definately be 25lbsf.

This is a simple test you can do at home.

Put one gallon of water in a bucket, water is 8 pounds plus the bucket weight. Next empty a 1 pint plastic drinking bottle to 1/2 full or 8 oz, replace and tighten the cap, equals 1/2 pound. Put the bucket with water onto a scale, add the 1/2 full bottle of water and read the weight change. Should go up by 1/2 pound, but will it? You added a 1/2 pound of mass, however it is bouyant mass and doesn't weigh a 1/2 pound suspended in water.

This is interesting.  Brings up the point about swim bladders in fish. http://www.answers.com/topic/buoyancy?cat=technology

I remember once seeing a movie based on the life of Charles Lindberg, and as he was flying across the ocean, he noticed a fly in the plane. Now, having calculated his weight down to the literal ounce to conserve fuel, he wondered if, while the fly was in flight, whether or not he added any weight to the airplane, as opposed to if the fly landed on something.

Ponder that one awhile.

OK, I added to this post. Experiment conducted!  I have a very accurate balance beam scale. I put a bowl and filled it with water to an exact weight of 14 ounces.  I then took a small plastic sealable container and filled it with enough water to equal a combined

weight of 2 ounces.  Placed the original bowl on the scale and placed the sealed container in the water filled bowl. It floated by the way.   Total weight: exactly 16 ounces.

US wieghts and measures 1 Gal of pure water is 8.33 lbs

8.33 x 20 = 166.6 plus the bass 5 lbs

166.6 = 5 lbs = 171.6 total wieght of bucket contents . Regardless of the percived with due to bouyancy the contents of the bucket wiegh this amount,

[tyrius.]

Unless the addition of the fish caused some water to spill out of the container the weight will be 25lbs.

Air in swim bladders and such don't weigh anything on land either.

[wilsonm1]

i am not sure what the answer to this is, everybodys sounds reasonable. some bass tournaments i watch on tv weigh in in tanks. think about this. wouldnt it be unfair for everyone after the first guy weighing in because the water taken out with the first limit. ???

20lbs. of water,  not 20 gallons.  But I agree on the formula.

[fish jones]

if you were to pick up the bucket you would be lifting 25 lbs.

[fishbear]

This ummmmmmmmmm stuff : is why I failed algebra, and calculus and geometry....  I hate forumulas and theories and trying to prove or disprove them.  I got a headache from just reading this....  ;D ;D ;D :-/ :-/ :-/

Is this still being debated?  It can easily be solved with this:

OPPSSS , THANKS I didn't catch that, the water not the bass

[GitRDoneIke23]

20 + 5= 25.

I don't need no PHD in smartness to tell ya that!

Got R Did!

This is how you resolve a debate, with factual data. Vessel displacement doesn't mean the vessel weighs any less when floating in or water. Few can comprehend formulas, almost everyone can understand a practical expirement that demstrates theory.

The airbladder nuetralizes the 5 lb bass so it doesn't sink at rest when at a specific depth, the bass still weighs 5 lbs.

WRB.

If the fly landed it would add it's weight, does the fly weigh the same in flight?

[bchlr]

whether or not the bass floats or sinks down, dead or alive, its buoyancy etc...(as long as the fish doesnt move when the result is taken) will not affect the total mass/weight read from the scale. how the bass interacts with the water and the forces accounted make up the internal energy of stuffs INSIDE the tank (which, ideally, should be a closed system), and they cancel one another out perfectly to achieve a dynamic equilibrium unless the fish jumps out of the water for example. so yes, 20 lbs water + 5 lbs bass = 25 lbs. hope i make sense

weigh your boat,....put a bass in the livewell,....weigh your boat again.

The correct answer is "dinner."
