平面直角坐标系xOy中，椭圆C： $\frac{x^2}{a^2}+\frac{y^2}{b^2}$ =1（a＞b＞0）的长轴长为2，抛物线E：x²=2y的准线与椭圆C相切．

（Ⅰ）求椭圆C的方程；

（Ⅱ）若直线l与椭圆C相交于A，B两点且与抛物线E在第一象限相切于点P，线段AB的中点为D，直线OD与过P且垂直于x轴的直线交于点M，求 $\frac{S_{△PFG}}{\left|OG\right|}$ 的最小值及此时点P的坐标．

已知二次函数y=a(x-m)²-2a(x-m)（a,m为常数，且a≠0）.
（1）求证：不论a与m为何值，该函数的图象与x轴总有两个公共点；
（2）设该函数的图象的顶点为C，与x轴交于A，B两点，当△ABC是等腰直角三角形时，求a的值．
