Disneyland

   Would you like to see the whole world on one trip(旅行)? Welcome to the wonderful world of Disneyland. In Disneyland, you can see many different countries(国家) in one day. You can see people and buildings（建筑物） from every country. You can eat many different kinds of food in one day. There are restaurants from Australia, England, America, Japan and China.

  There is much to do in Disneyland. You can do a lot of shopping and buy many funny and beautiful gifts. You can see a mouse taller than you! His name is Mickey Mouse.

已知函数$f\left(x\right)$是R上的偶函数,且$f(1-x)=f(1+x)$,当$x\in 0,1$时,$f\left(x\right)=x^2$,则函数$y=f\left(x\right)-{\log }_{5}x$的零点个数是（）

某同学要用电阻箱和电压表测量某水果电池组的电动势和内阻，考虑到水果电池组的内阻较大，为了提高实验的精度，需要测量电压表的内阻．实验室中恰好有一块零刻度在中央的双向电压表，该同学便充分利用这块表，设计了如图所示的实验电路，既能实现对该电压表的内阻的测量，又能利用该表完成水果电池组电动势和内阻的测量．他用到的实验器材有：待测水果电池组（电动势约4V，内阻约50Ω）、双向电压表（量程为2V，内阻约为2kΩ）、电阻箱（0﹣9999Ω）、滑动变阻器（0﹣200Ω）、一个单刀双掷开关及若干导线．
