如图所示,底面积为S的薄壁玻璃杯放在水平桌面上,其中盛有重为G₁的水,将一块重为G₂、边长为d的正立方体木块放入水中漂浮,杯中水未溢出,水面升高了h。下列说法错误的是(    )

如图所示,悬吊的实心金属球缓慢浸没于倾斜的盛满水的大烧杯中,则从大烧杯溢出流入小烧杯中的水和此金属球的关系,下列说法正确的是(    )

如图甲所示,在一只薄塑料袋中装水过半(未满),用细线扎紧袋口,用弹簧测力计测得其所受重力为9N;再将这个装水的塑料袋浸入烧杯内的水中,如图乙,当弹簧测力计示数为6N时,袋内水面与烧杯中的水面相比(不计塑料袋和细线的重)(    )

在如图所示的实验中,可以探究物体所受浮力大小与物体排开液体的体积有关的是图中的(    )
