4.氧气分子在不同温度0^C和100^C下的速率分布如图所示,NN是分子数所占的比例。由图线信息可得到的正确结论是A..同一温度下,速率大的氧气分子数所占的比例大B.100^C时图像的面积大于0^C时的面积C.温度越高,一定速率范围内的氧气分子所占的比例越小D.温度升高使得速率较小的氧气分子所占的比例变小

18.(16分)如图所示,一个质量为M的中性粒子A静止于点,现以O点为坐标原点建立平面直角坐标系xOy,并在空间内添加垂直xOy平面向外的磁场,其中一、四象限的磁场I磁感应强度为2B,二、三象限的磁场Ⅱ磁感应强度为B.现粒子A瞬间一分为二,成为粒子P、Q,粒子P电荷量为一质量m=kM(k<1),速度沿x轴正方向,粒子Q质量为(1-.-k)M,粒子P、Q的动能之和为E,P粒子在磁场I中的运动周期为T1,粒子Q在磁场Ⅱ中的运动周期为T2。。已知粒子重力不计,忽略两粒子之间的相互作用力。(1)求T1与T2的大小之比(用k表示);(2)若粒子P在磁场I中运动的半径取得了最大值,则k应取多大,并求解此最大半径的值;(3)若P粒子的速度在xOy平面第一象限内与x轴正方向夹角30^,k取多大时,两粒子会在以后的运动过程中相遇。(已知若cos=34,则取=64^)
