湛江市2023届高中毕业班调研测试物理参考答案1.A【解析】本题考查冲量和动量守恒，目的是考查学生的理解能力。甲、乙组成的系统动量守恒，甲对乙的冲量与乙对甲的冲量大小相等，方向相反，选项A正确；甲、乙组成的系统动量守恒，甲、乙的动量变化大小相等，方向相反，选项B错误；在推动过程中，甲、乙之间的相互作用力等大反向，但无法确定甲、乙对地位移的大小关系，因此无法判断做功的关系，即甲的动能增加量不一定等于乙的动能减少量，选项C错误；甲、乙的质量关系未知，无法判断加速度的大小关系，选项D错误2.C【解析】本题考查万有引力与航天，目的是考查学生的理解能力。载人飞船的发射速度大于第一宇宙速度，小于第二宇宙速度，选项A错误；“天和”核心舱在距地球约400千米的高空绕地球做匀速圆周运动，由匀速圆周运动中万有引力提供向心力，有分=m答(R十A,可知周期越大，轨道半径越大，所以同步卫星的轨道半径大于核心舱的轨道半径，由%=，可知轨道半径德大，加速度越小，选项B错误，C正确；要使载人飞船与核心舱分离后返回地球，应减速使飞船做向心运动而降低轨道高度，选项D错误。3D【解析】本题考查分子动理论，目的是考查学生的理解能力。杯内空气温度降低，由号=号，可知杯内压强减小，杯内空气的压强小于外界大气压强，选项A错误；17℃时与97℃时相比，杯内空气的体积不变，质量不变，所以密度不变，选项B、C错误；17℃时与97℃时相比，杯内空气的压强减小，对杯壁单位时间内、单位面积上的碰撞次数减少，选项D正确。4.B【解析】本题考查电容器，目的是考查学生的推理能力。根据电容的定义式C=号，解得Q=0.064C,故放电过程的均电流1=？-及A=16A,透项A错误，B正确：当电容器的电压达到击穿电压时，电容器将会损坏，所以4kV电压不是击穿电压，选项C错误；电容器的电容与电容器的带电荷量无关，所以当电容器放完电后，其电容保持不变，选项D错误。5.C【解析】本题考查物体衡，目的是考查学生的推理能力。桥面受到Tc、TB与重力的作用处于衡状态，根据共点力衡条件，重力经过Tc、TB的交点A,所以桥面的重心在桥面与立柱的交点D处，选项A错误；桥面受到Tc、TB与重力的作用处于衡状态，则Tc、TB的合力与桥面受到的重力等大反向，即Tc、TB的合力竖直向上，则钢索对塔柱的拉力的合力竖直向下，选项B错误；把Tc、TB分别沿水方向和竖直方向分解，水方向的分力等大反向，则有TAc sin a=TAB sin B,又aTB,选项C正确、D错误。6.C【解析】本题考查气体实验定律，目的是考查学生的推理能力。T-p图像从。到b过原点，由兴=C可知从a到b气体的体积不变，则从a到b外界对气体不做功，选项A、D错误；从a到b气体温度降低，气体分子的均动能一直减小，并不是所有气体分子的动能都一直减小，选项B错误；根据热力学第一定律△U=W十Q,其中W=0,△U<0,可知气体一直对外界放热，选项C正确。7.B【解析】本题考查电磁感应和电路相关知识，目的是考查学生的推理能力。根据法拉第电磁感应定律，金属棒中产生的感应电动势E=B,结合闭合电路欧姆定律，回路中的感应电流1一是-B收，可见Ec1,c1,根据题意，金属棒向右运动的过程中，切割磁感线的长度1随时间先均匀增大，后不变，最后均匀减小，而电围两瑞的电压等于电源电动势，选项A错误.B正确：金居棒所受安培力大小F一=，P==B发。∝,结合l随时间变化的规律可知P先按抛物线规律增大，后不变，最后再按抛物线规律减小，选项C、D错误。【高三物理·参考答案第1页（共3页）】·23-80C·
