Archimedes (287-212 bce) was a greek scientist with many accomplishments. he is best - known from the legend of solving a problem given to him by king heron ii of syracuse (sicily).the king suspected that his crown, which was supposed to be made from pure gold, contained some silver alloy, and he asked archimedes to prove or disprove his suspicion. (it turned out the crown did contain silver.) according to a roman account, while pondering a question archimedes went to the baths and as he noticed the water flowing out upon immersion, he recognized a solution to the problem and run home shouting "eureka! " (greek for "i have found it.") it has also gotten him thinking about buoyancy, and the buoyant force, responsible for some objects' ability to float, is named after him. how would you experimentally determine whether or not the crown was pure gold?

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
