1.2023年春节期间,中国科幻电影《流浪地球2》热映.《流浪地球》系列影片设定:若干年后,太阳上的氢元素将被耗尽,太阳由“氢核聚变”阶段进入“氦核聚变”阶段,并成为一颗红巨星,地球将被太阳吞没、气化.因此,人类启动了“流浪地球”计划.人类的自救之旅的第一阶段是“刹车阶段”,利用2000台安装在地球赤道上的“转向式行星发动机”,通过喷射高能高压的粒子流,推动地球停止自转;第二阶段是“逃逸阶段”,利用“推进式行星发动机”推动地球加速,增大公转速度,逐渐脱离太阳系,开启“流浪”之旅.根据以上素材,结合所学,判断下列说法正确的是A.不考虑其它因素,地球停止自转的过程中,赤道上的物体所受重力逐渐减小B.不考虑其它因素,地球停止自转的过程中,南北极处的物体所受重力逐渐增大C“转向式行星发动机”的喷口方向应该与自转速度方向相反,“推进式行星发动机”的喷口方向应该与公转速度方向相反D.聚变要克服原子核之间的库仑斥力,因此氨核聚变比氢核聚变需要的温度更高
