∵p=ρgh
∴加水1000g时水的深度：h1=p1ρg=400Pa1×103kg/m3×10N/kg=0.04m=4cm；
加水2000g时水的深度：h2=p2ρg=800Pa1×103kg/m3×10N/kg=0.08m=8cm；
加水3000g时水的深度：h3=p3ρg=1200Pa1×103kg/m3×10N/kg=0.12m=12cm；
加水4300g时水的深度：h4=p4ρg=1600Pa1×103kg/m3×10N/kg=0.16m=16cm；
加水5900g时水的深度：h5=p5ρg=2000Pa1×103kg/m3×10N/kg=0.20m=20cm；
加水7500g时水的深度：h6=p6ρg=2400Pa1×103kg/m3×10N/kg=0.24m=24cm；
对表格中数据进行处理及各状态分析如下：
m/g100020003000430059007500p/Pa4008001200160020002400h/cm4812162024△h/cm4△m/g10001600加水情况图示①
②③或④
⑤⑥①～③，m与h成正比，③～④，m与h不成正比，说明物体可能已经漂浮或已经全部浸没，④～⑥△m与△h成正比．
图④～⑤中，增加水的质量：△m④～⑤=ρSA△h④～⑤，
∴容器的底面积：SA=△m④～⑤ρ△h④～⑤=1600g已赞过已踩过你对这个回答的评价是？评论收起 ._1uevpeq{zoom:1;background-color:#fff;border:0;margin-bottom:10px;padding:30px 0 20px 42px;position:relative}._1uevpeq.ec-1841{padding:20px
