阅读共享单车后回答． 共享单车 骑自行车出行有很多益处不仅可以节能减排缓解交通压力而且骑车时人需要消耗体能可以强身健体．一个成年人在水平路面上骑车时所受阻力大约20N． 近年来我国多个城市推出了多种新型共享单车广州市的许多街道旁也随处可见如图甲所示这种单车外观结构简单单车的质量约25kg比普通自行车质量要大些． 单车的车锁内集成了嵌入式芯片GPS定位模块和SIM卡等便于监控单车的具体位置和状态．其工作原理如图乙所示．用户可使用手机下载单车APP查看并找到单车的位置然后用手机扫描车身上的二维码通过手机网络发送电磁波到云端请求解锁云端收到请求后识别该车辆并发送解镇指令单车执行解锁指令自动开锁用户便可以开始骑行手机AP就显示计时计价等信息．此外当用户在骑行过程中踩动脚踏板可将机械能转化为电能为车内蓄电池充电以满足单车定位和自动开锁等过程中的用电需要． 请根据上述材料回答下列问题 1此种单车和手机之间是利用传递信息的若此种单车使用的GPS信号的频率是1800GHz而手机中蓝牙通信信号电磁波的频率是25GHz则该GPS信号的波长手机蓝牙通信信号的波长选填“大于“或“小于”． 2单车在骑行过程中可将机械能转化为电能是利用现象实现的．乐乐某次扫码后骑行8km耗时30min此次骑行的平均速度为km/h． 3一个成年人在水平路面上以正常的速度保持匀速骑行半小时消耗的能量最接近． A.2×103JB.2×105JC.2×107JD.2×109J 4乐乐放学回家途中把自行车骑得飞快妈妈看见后警告他说“以后骑自行车慢点不然很危险”是因为质量一定时速度越大越大行驶中危险性大．
