如图甲所示，空间存在B=0.5T、方向竖直向下的匀强磁场，MN、PQ是处于同一水平面内相互平行的粗糙长直导轨，间距L=0.2m，R是连接在导轨一端的电阻，ab是跨接在导轨上质量为m=0.1kg的导体棒．从零时刻开始，通过一小型电动机对ab棒施加一个牵引力，方向水平向左，使其从静止开始沿导轨做加速运动，此过程中棒始终保持与导轨垂直且接触良好．图乙是棒的v-t图象，其中OA段是直线，AC段是曲线，CE段是平行于t轴的直线，小型电动机在12s末达到额定功率P=4.5W，此后保持功率不变，在t=17s时，导体棒达到最大速度10m/s．除R外，其余部分电阻均不计，g=10m/s²．

（1）求导体棒ab在0-12s内的加速度大小；

（2）求导体棒与导轨间的动摩擦因数μ及电阻R的阻值；

（3）若导体棒ab从0-17s内共发生位移102m，试求12-17s内，R上产生的焦耳热量是多少．

When I was a kid, I always used to wonder how in the world my father work outside in the winter without a coat. It could be minus 20 degrees centigrade and there’d be Dad, removing snow, or perhaps chopping some wood --- his coat thrown  aside--- wearing a shirt , a cap, and a pair of gloves.

“Aren’t you cold, Dad?” I’d ask. “No,” Dad would reply. “I’m not cold--- working too hard to be cold.”

Many times I wondered whether my father was an extremely tough man, or whether he was foolish.

One time when I was quite young, perhaps five or so, I went ice fishing with Dad. It was a bright, clear day—and bitterly cold.

After we’d been out on the ice for a little while, my feet started getting cold.

“Daddy, my feet are cold.” I said.

“Yeah, it’s cold out here today,” he replied.

“Tell you what,” he said. “Walk around. Make some circles in the snow. See how many different patterns you can make. That will get your feet warm.”

Now, I was just a little girl at the time but I remember thinking, “How in the world will walking around in the snow make my feet warm? Dad must be out of mind.

But he was my father, after all. I made circles in the snow. I made squares. Pretty soon I was having so much fun making patterns in the snow. I forgot about my feet being cold.

Now, all these years later, I know, too, from personal experience how my father was able to take his coat off and work outside in the winter wearing just a shirt, a cap and gloves. Because I do it, too. “Aren’t you cold?” my husband asked one winter day. “No,” I replied. “I’m not cold—working too hard to be cold.”

I hope my husband has decided I’m both tough and smart. But I guess quite a bit of the time he thinks I’m foolish.

Wherever Dad is in that great big farm in the sky—I’m sure he can’t help but smile whenever I take my coat off while I’m working outside in the winter.
