江苏省2024届高三年级第一学期期初学情调研迎考卷-物理答案
江苏省20232024学年高三第一学期期初迎考试卷物理参考答案及评分标准1.C 解析:一个84218Po核含有84个质子,故A错误;由质量数和电荷数守恒可知Y射线是α射线,穿透力最弱,故B错误;由于Po核比Rn核更稳定,所以Po核比Rn核的比结合能大,故C正确;半衰期与物理、化学变化无关,故D错误.2.A 解析:地球到太阳的距离r越大,线速度越小,角速度越小,向心加速度越小,故A正确,B、C错误;由GMmr2=m4π2T2r得太阳的质量M=4π2r3GT2,即可以根据地球的公转周期求出太阳的质量,无法求出地球质量,故D错误.3.C 解析:设一个篮子的质量为m,连接下篮的绳子的拉力为T2,对下篮...
