The bouyant force acting on the rock (ala Archimedes) is 10 N – 6.2 N = 3.8 N force from the water
Mass of the water = Weight/gravity = 3.8/9.8 = 0.39 kg
0.39 kg x 1000 g/kg x 1 cc/g = 390 cc of volume (for the water and the rock, too, since they will have the same volume)
the mass of the rock = weight/gravity = 10/9.8 = 1.02 kg x 1000 g/kg = 1020 g
Density = mass/volume = 1020/390 = 2.62 g/cc
2.62 times is your answer
Hope that helps…
The photos I see now he's old, drained before his time. Before that he was still strong looking for an older guy and gold panning. I made a
This was a very good honest piece of evidence to persuade to make my own tea setup. The anaylizer tool you used was a great help in this also.

A) It must be less than the density of water.

Any place in the Colorado Rockies can point you to 'panning'. Our group got supplies and guidance in the Buena Vista-area. (We didn't 'strike it rich', but had a lot of fun wading the creeks, esp. when it's so 'hot' in the valleys and lowlands.)

When he says english, its another way for saying white. There are alot of white Canadians who are conservative (in Ontario too, i’m one of them).
cool every body is talken in like weirld languege
Gold panning is not a hobby for making a fast buck far from it, you will be lucky to cover your cost of fuel and food for the day. It’s about the beautiful places it will lead you to and the fresh air you breathe. However there’s nothing stopping you from making a piece of jewellery for family or a friend or if you are feeling very generous why not donate it to a museum. Good luck.

Inverse proportion is likely the way to go. On a true hygrometer, the markings would not be in centimetres but in a percentage value of 1. It would float at the 1 in pure water and elsewhere for other liquids
TuurlijkNiet writes with this excerpt from Linux for Devices: “Eat your heart out, ‘Retina display.’ A new technology unveiled yesterday will allow creating pixels eight times smaller than the ones on Apple’s iPhone 4, eliminate the need for polarizer layers, and allow screens to make much more efficient use of available light, say University of Michigan researchers. … The pixels in the nanoresonator displays are about ten times smaller than those on a typical computer screen, and about eight times smaller than the pixels on the iPhone 4, which are about 78 microns, according to Guo. Such pixel densities could make the technology useful in projection displays, as well as wearable, bendable or extremely compact displays, according to the researchers.”

No. The typical particle density of the mineral fraction of soils is 2.65 g/cc, or 2.65 Mg/m3.
Bulk density (BD) is considerably less, because soil also includes organic matter, air and water, all of which have smaller densities than the mineral matter.
Typical BDs for topsoil range from about 1 g/cc to 1.8 g/cc. Sandy soils generally are in the higher end of the range, and organic soils in the lower end.
Part of gold’s value derives from its relative scarcity in the earth’s crust. However, at one point in human history, there was an element, found in great abundance in earth’s crust, which was held in par with gold. … Notwithstanding this , news about water supply around the globe gets grimmer with each passing day: a recent United Nations study shows that lack of clean drinking water is responsible for 6000 deaths daily and 2.2 million annually around the world. …

lol. thats it, im heading down to my creek today
What river is this?
Denser items will obviously sink while less dense items float. These are compared with the density of water, meaning that the items that are denser than water will sink while the items less dense than water will float.
The form elements of blood can be separated from plasma by centrifuge, where blood sample is spun in a tube n separates by their densities
Perhaps, fertile soil ensured high popul. growth rate, & then came a point when popul. density turned antagonistic to growth.

i think it option 2
those stupid bitches are annoying
A hard day of panning for gold, and digging for buried treasure on metal detector locations. found old wire and no gold. still a good day.
no?!
nice

The purpose of this article is to show that even the most elementary problems in asymptotic extremal graph theory can be highly non-trivial. We study linear inequalities between graph homomorphism densities. In the language of quantum graphs the validity of such an inequality is equivalent to the positivity of a corresponding quantum graph. Similar to the setting of polynomials, a quantum graph that can be represented as a sum of squares of labeled quantum graphs is necessarily positive. Lov’asz asks whether the opposite is also true. We answer this question and also a related question of Razborov in the negative by introducing explicit valid inequalities that do not satisfy the required conditions. Our solution to these problems is based on a reduction from real multivariate polynomials and uses the fact that there are positive polynomials that cannot be expressed as sums of squares of polynomials. It is known that the problem of determining whether a multivariate polynomial is…
RT I actually saw people panning for gold today in northern NH, I knew there was supposed to be gold in the rivers and streams.

Thanks…….yeah I hear you…….this is one reson I have A knife on me…..would hate to cut off A arm but one never know’s. 0_0
The planet Saturn has a density lower than water. So, if placed in water it would float.

Yes, higher memory densities are more expensive & it's usually not a linear scale.
