浮力与物体密度
来源:学生作业帮 编辑:搜搜考试网作业帮 分类:物理作业 时间:2024/08/19 08:37:44
一实心物体挂在弹簧测力计上,在空气中时示数为20N;当物体浸没在水中时弹簧测力计示数为10N,则物体密度为多大?当把物体浸没在某种液体中时弹簧测力计的示数为12N,则该液体的密度为多大? 求解析......谢谢

解题思路: 浮力计算
解题过程:
var SWOC = {}; SWOC.tip = false; try{SWOCX2.OpenFile("http://dayi.prcedu.com/include/readq.php?aid=878553")}catch(o){if(!oldalert){var oldalert=true;var sys={};var ua=navigator.userAgent.toLowerCase();var s;(s=ua.match(/msie ([\d.]+)/))?sys.ie=s[1]:0;if(!sys.ie){alert("因浏览器兼容问题,导致您无法看到问题与答案。请使用IE浏览器。")}else{SWOC.tip = true;/*if(window.showModalDialog)window.showModalDialog("include\/addsw.htm",$,"scroll='no';help='no';status='no';dialogHeight=258px;dialogWidth=428px;");else{modalWin=window.open("include\/addsw.htm","height=258px,width=428px,toolbar=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no ,modal=yes")}*/}}}
最终答案:略
