47、选A D 选项：当桨划水的时，由于力的作用是相互的，水对桨也有力，水对桨的力作用在桨上，相当于作用船上，所以可以使船前进。故选2.可能错误 :选 A 受到生活经验的影响,而忽视了 空中 这一重要条件正确答案 :B 因为球在空中了,在空中的球脚是没有作用力的,只受重力了 . 3.D 4.B 5.正确答案 B 分析：不可是，弹簧称受到了拉力，一定有示数弹簧称受到的相反方向的两个力，运算时只能是相减而不能相加，所以不可能是各用了有力不能显示，所以也不能是注意弹簧称使用时处于静止一定受到一对平衡力，这两个力大小是相等的方向是相反的但显示数值时只显示一个力的大小，所以选6.B 7.C 8.B 9.先增大
