如图所示,两根足够长、电阻不计、间距为d的光滑平行金属导轨,其所在平面与水平面夹角为θ,导轨平面内的矩形区域abcd内存在有界匀强磁场,磁感应强度大小b方向垂直于斜面向上,ab与cd之间相距为L0金属杆甲、乙的阻值相同,质量均为m,甲杆在磁场区域的上边界ab处,乙杆在甲杆上方与甲相距L处,甲、乙两杆都与导轨垂直。静止释放两杆的同时,在甲杆上施加一个垂直于杆平行于导轨的外力F,使甲杆在有磁场的矩形区域内向下做匀加速直线运动,加速度大小a=2gsinθ,甲离开磁场时撤去F,乙杆进入磁场后恰好做匀速运动,然后离开磁场。

(1)求每根金属杆的电阻R是多大?

(2)从释放金属杆开始计时,求外力F随时间t的变化关系式?并说明F的方向。

(3)若整个过程中,乙金属杆 * * 生热量Q,求外力F对甲金属杆做的功W是多少?

Walking through my train yesterday, staggering from my seat to the buffet and back, I counted five people reading Harry Potter novels. Not children-these were real grown-ups reading children’s books,
Maybe that would have been understandable. If these people had jumped whole-heartedly into a second childhood it would have made more sense. But they were card-carrying grown-ups with laptops and spreadsheets returning from sales meetings and seminars. Yet they chose to read a children’s book.
I don’t imagine you’ll find this headcount exceptional. You can no longer get on the London Tube and not see a Harry Potter book. Nor is it just the film; these throwback readers were out there in droves long before the movie campaign opened.
So who are these adult readers who have made JK Rowling the second-biggest female earner in Britain (after Madonna) As I have tramped along streets knee-deep in Harry Potter paperbacks, I’ve mentally slotted them into three groups.
First come the Never-Readers, whom Harry has enticed into opening a book. Is this a bad thing Probably not. Writing has many advantages over film, but it can never compete with its magnetic punch. If these books can re-establish the novel as a thrilling experience for some people, then this can only be for the better. If it takes obsession-level hype to lure them into a bookshop. that’s fine by me. But will they go on to read anything else Again, we can only hope.
The second group are the Occasional Readers. These people claim that tiredness, work and children allow them to read only a few books a year. Yet now—to be part of the crowd, to say they’ve read it—they put Harry Potter on their oh-so-select reading list. It’s infuriating, and maddening. Yes, I’m a writer myself, currently writing difficult, unreadable, hopefully unsettling novels, but there are so many other good books out there, so much rewarding, enlightening, enlarging works of fiction for adults; and yet these sad cases are swept along by the hype, the faddism, into reading a children’s book.
The third group are the Regular Readers, for whom Harry is sandwiched between McEwan (英国当代作家) and Balzac, Roth (德国现代诗人) and Dickens. This is the real baffler—what on earth do they get out of reading it Why bother But if they call rattle through it in a week just to say they ve been there—like going to Longleat (朗利特山庄英国名胜) or the Eiffel Tower—the worst they’re doing is encouraging others.
