如图所示,一个容积为500cm (1)由ρ=mV可得,0.4kg水的体积:V水=m水ρ水=400g1g/cm3=400cm3;(2)石块总体积:V石=V瓶-V水=500cm3-400cm3=100cm3.答:(1)瓶中水的体积为400cm3;(2)乌鸦投入瓶子中的石块体积100cm3.
如图所示,一个容积V (1)由ρ=mV得,瓶内水的体积:V1=m水ρ水=0.3kg1.0×103kg/m3=3×10-4m3=300cm3.(2)由题意可知,石块的总体积:V2=V0-V1=500cm3-300cm3=200cm3.(3)由ρ=mV得,石块的质量:m石=ρ石V2=2.6g/cm3×200cm3=520g.
的水.乌鸦为了喝到瓶子里的水,就衔了很多的小石块填到瓶子里,当水到瓶口时,瓶子、石块和水的总质量为1.35kg. (1)由ρ=mV,所以瓶子里水的质量m水=ρ水V水=1g/cm3×200cm3=200g;(2)石块总体积:V石=V瓶-V水=450cm3-200cm3=250cm3;瓶内石块的总质量:m石=m总-m瓶-m水=1.35kg-0.5kg-0.2kg=0.65kg=650g,小石块的密度:ρ=m.
乌鸦看见一个装有水的瓶子,然后将许多石头扔进去,水逐渐升高,最后喝道水了的英语翻译 A crow found a bottle full of water and then put a lot of stone into it.The level of water in this bottle arose so that the crow was able to drink the water in the end.
乌鸦看见一个装有水的瓶子,然后将许多石头扔进去,水逐渐升高,最后喝道水了的英语翻译 A crow saw a bottle with water,and threw some stones into the bottle.The water gradually increased,and finally the crow drinked the water.乌鸦看见知一个装有水的瓶道子,然后将许多石头扔进去版,水逐渐升高,最后喝到权水了。
如图所示,一个容积V (1)由ρ=m V 可得,瓶中水的体积:V 1=m 1 ρ 1=0.2×1 0 3 g 1.0g/cm 3=200cm 3;(2)乌鸦投入瓶子中的石块的体积:V 2=V-V 1=450cm 3-200cm.
