某化学兴趣小组参观了一个石灰厂时，带回了一些石灰石样品，同学们利用这些石灰石样品做了如下实验：取样品10g放入烧杯中，将50g稀盐酸分5次加入，实验过程所得的数据如表所示（已知石灰石样品中的杂质不参与反应，也不溶于水）．根据实验数据计算：

已知函数f（x）=$\frac{1}{2}$sinωx+$\frac{\sqrt{3}}{2}$cosωx（ω＞0）的周期为π．

（Ⅰ）求ω的值，并在下面提供的坐标系中画出函数y=f（x）在区间0，π上的图象；

（Ⅱ）函数y=f（x）的图象可由函数y=sinx的图象经过怎样的变换得到？

增加：在缺词处加一个漏字符号（∧），并在其下面写出该加的词。

删除：把多余的词用斜线（\）划掉。

修改：在错词下划一横线，并在该词下面写出修改后的词。

注意：1）每处错误及其修改均仅限一词；

2）只允许修改10处，多者（从第11处起）不计分。

    Social work is the quite new and growing career in China. It involves improving society, solve problems in relationships between people and helping people improve their lives.
