Question

3. Which of the following is true about an object that floats in water? (1 point)
The object is less dense than frozen water.
The mass of the object is less than that of water.
The density of the object is less than that of water.
The volume of the water is greater than the object’s volume.

Answer 1

The density of the object is less than that of water

Answer 2

no scratch that it's the volume fothe water is greater thatn the object's volume @josesito

Answer 3

the correct answer is to be found in the law of archimedes: "Een lichaam ondervindt een opwaartse kracht gelijk aan het gewicht van de verplaatste massa" A body feels an upward force equal to the weight of the mass displaced water (or gas).

Answer 4

If the object were a boat, the answer of brookester6 could possably be wrong, for example if the object is made of steel (for example a steel boat), but still floats in water.

Answer 5

ok ok we gotchya aristotle... lol

Answer 6

ikr

Answer 7

haha but thanks for ur help anyway @fretje

Answer 8

@brookester6 why do the life buoys in our city at the water keep dissappearing. I don't understand. While they can help saving lives, vandals shouldn't touch them.

Answer 9

uhhhhhhhh

Answer 10

thnx and wat happened to Brookester6

Answer 11

can i ask, @josesito is this for a school test, vital for passing the grade? If it is any of the answers it should be answer 3 The density of the object is less than that of water. because it is open to discussion(a boat can be interpreted as hull plus the content instead of hull only), all three other answers can be proven wrong. shall i prove them wrong?

Answer 12

yes you should and this is for a school test

Answer 13

which of the following explains how water causes rocks to weather ( 1 piont)
water can melt rock material
water freezes in the cracks and expands, causing breaks
water reacts with the rock and produces gases
all of the above

Answer 14

Which of the following is true about an object that floats in water? (1 point)
first answer:
The object is less dense than frozen water.
wrong because an object like a needle can float on water (you should try this) because the water hydrogen bonds can create a surface tension strong enough for keeping objects floating, example: the http://en.wikipedia.org/wiki/Gerridae

Answer 15

Which of the following is true about an object that floats in water? (1 point)
second answer:
The mass of the object is less than that of water.
Wrong because since is said "than that of water", this is a general description of something, where "water" can be "all water in the universe", or "water" can be "the displaced water by the object", or "water" can be "one molecule of water"and thus the answer is not specific enough to serve as an answer. In logics, this , I think, what is called a "generalisation".
I make this mistake often in discussions.

Answer 16

ummmmmmm yeah sooo i just sorta know it from 7th grade sooo yeah :P no need for explanation.. i think ur just wasting ur time :D) lol hey @josesito

Answer 17

Which of the following is true about an object that floats in water? (1 point)
fourth answer:
The volume of the water is greater than the object’s volume.
Is wrong in following case.
A petri dish with 100cubic centimeter water with a 101 cubic centimeter styrofoam block floating on it (styrofoam block's volume being greater).

@brookester6 is the fourth answer the one you took?

Answer 18

hey brookester so wrud now

Answer 19

@josesito http://en.wikipedia.org/wiki/Erosion says water freezes in the cracks and expands, causing breaks.
Also carbondioxide is an acid that solves rock, but that is not exactly one of the answers, so I'd choose from the four answers, the answer two,"water freezes in the cracks and expands, causing breaks" but I am no genius yet.
