2017年4月26日9时我国首艘国产航母如图在大连造船厂正式下水当航母静止在水面上时其受到的浮力填大于等于或小于重力在水面下10m深处的船体受到海水的压强为Pa．ρ海水=1.0×103kg/cm3g取10N/kg
小美用手把一个重为0.4N体积是2.7×10﹣5m3的玩具球完全浸没到水中玩具球受到的浮力是N放手后玩具球将填上浮下沉或悬浮．g取10N/kgρ水=1.0×103kg/m3

小明在学习浮力时做了一些关于浮力的实验1为了验证漂浮在水面上的木块所受到的浮力也满足阿基米德原理他做了图中所示的实验实验过程中弹簧测力计的示数分别为F1F2F3F4它们的大小关系是A．F3-F1=F4-F1 B．F1=F4F2=F3 C．F2=F3-F1 D．F2=F4-F12为了探究木块上浮时所受的浮力和重力之间的关系小明应该选用图中图甲乙和选填丙或丁3小明进一步猜想物体所受浮力大小是否与物体的密度有关针对这个问题他选用以下实验器材进行探究弹簧测力计体积相同的铜块和铁块质量相同的铜块和铁块烧杯细线和水实验步骤如下①用细线将所选的铜块和铁块先后挂在弹簧测力计上测出它们的重力分别为G1G2②将所选的铜块挂在弹簧测力计上并浸没水中记下弹簧测力计的示数F1③将所选的铁块挂在弹簧测力计上并浸没水中记下弹簧测力计的示F2通过上述实验验证了猜想则a．为了使上述实验能顺利的完成小明应该选择相同的铜块和铁块b．利用以上实验数据比较若说明浮力大小与物体密度无关
