5、河北省9+1联盟2025-2026学年高三上学期调研考试数学答案
D．同一地区，单摆的固有频率只取决于单摆的摆长，则只有摆长等于驱动摆的摆长时，单摆的振幅能够达到最大，这种现象称为共振，故D正确。
本题选不正确的，故选C。
【分析】单摆在摆动过程中多次通过同一位置时，位移相同，加速度相同，速度大小相同，但方向可能不同；4个单摆中，由某个摆摆动从而带动其它3个单摆做受迫振动，受迫振动的频率等于驱动力的频率；受迫振动中，当固有频率等于驱动力频率时，出现共振现象，振幅达到最大。
11．【答案】C
【知识点】受迫振动和共振；多普勒效应
【解析】【解答】A．系统的固有频率只与系统本身性质有关，与驱动力频率无关，故A错误；
B．只有驱动力频率与系统固有频率相同时，才能发生共振，故B错误；
