如图7所示，水平的平行虚线间距为d=50cm，其间有B=1.0T的匀强磁场。一个正方形线圈边长为l=10cm，线圈质量m=100g，电阻为R=0.020Ω。开始时，线圈的下边缘到磁场上边缘的距离为h=80cm。将线圈由静止释放，其下边缘刚进入磁场和刚穿出磁场时的速度相等。取g=10m/s²，求：⑴线圈进入磁场过程中产生的电热Q。⑵线圈下边缘穿越磁场过程中的最小速度v。⑶线圈下边缘穿越磁场过程中加速度的最小值a。

  The 1980s was called the “Me Decade” because for many this time was marked by a fascination with the self. The idea that each person has a self may seem natuaral to us, but this concept is actually quite new. The idea that each human life is unique developed between the 11th and 15th centuries in Europe. Before that time, individuals were considered in relation to a group, and even today, many eastern cultures place more emphasis on the importance of a collective self than on a unique and independent self.

Both eastern and western cultures see the self as divided into an inner, private self and an outer, public self. But where they differ is in terms of which part is seen as the“real you.” Western culture tends to promote the idea of individuality—a self that is separated from other selves. In contrast, many eastern cultures focus on an inter-independent self that gets its diversity in large part from inter-relationship with others.

For example, a Confucian(孔子) idea stresses the importance of “face”—other people’s views of the self and maintaining one’s desired status in their eyes. In the past, some Asian cultures developed clear rules about the specific clothes and even colors that people in certain social classes and occupations were allowed to display, and these live on today in Japanese style manuals. This style of dress is at odds with such western practices as “casual Fridays,” which encourage employees to dress informally and express their unique selves.
