题实心铅球和实心铁球分别挂在弹簧测力计上,然后把他们分别浸没在水中称时,弹簧测力计的示数相同.若把他们分别浸没在酒精中再称时,弹簧测力计的示数为:(1)仍相同(2)悬挂铅球的弹簧测力计示数大(3)悬挂铁球的弹簧测力计示数小(4)不能确定错解实心铅球和实心铁球分别是浸没 The solid shot and the solid iron ball are hung on the spring dynamometer, respectively, and when they are immersed in the water respectively, the spring dynamometer shows the same number. If they are immersed in alcohol and weighed separately, the spring force is measured. The counts are as follows: (1) Still the same (2) The number of spring dynamometers for hanging shots is large (3) The number of spring dynamometers for hanging irons is small (4) Unable to determine the wrong solid shot and solid iron The balls are immersed
