如图所示,水平的平行虚线间距为d,其间有磁感应强度为B的匀强磁场.一个长方形线圈的边长分别为L1、L2,且L2<d,线圈质量m,电阻为R.现将线圈由静止释放,测得当线圈的下边缘到磁场上边缘的距离为h时,其下边缘刚进入磁场和下边缘刚穿出磁场时的速度恰好相等.求:

(1)线圈刚进入磁场时的感应电流的大小;

(2)线圈从下边缘刚进磁场到下边缘刚出磁场(图中两虚线框所示位置)的过程做何种运动,求出该过程最小速度v;

(3)线圈进出磁场的全过程中产生的总焦耳热Q

Extract 1

A stylish dining room with cream walls and curtains and black carpet as perfect foil to an eclectic array of furniture. Many of the pieces are classics of their particular era, and demonstrate how old and new designs can be happily mixed together. The prototype chair in the foreground has yet to prove its staying power and was thought up by the flat’s occupant. He is pictured in his living room which has the same decorative theme and is linked to the dining room by a high Medieval-styled archway where was once a redundant and uninspiring fireplace.

Extract 2

Old bathrooms often contain a great deal of ugly pipework in need of disguising. This can either be done by boxing in the exposed pipes, or by fitting wood paneling over them.

As wood paneling can be secured over almost anything — including old ceramic tiles and chipped walls — is an effective way of disguising pipework as well as being an attractive form of decoration. The paneling can be vertical, horizontal or diagonal.

An alternative way to approach the problem of exposed pipes is to actually make them a feature of the room by picking the pipework out in bright p colours.

Extract 3

Cooking takes second place in this charming room which; with its deep armchairs, is more of a sitting room than a kitchen, and the new Rayburn stove as a good Choice, as it blends in well with the old brick and beamed fireplace. There are no fitted units or built-in appliances, so all food preparation is done at the big farmhouse table in the foreground; and the china, pots and pans have been deliberately left on show to make an attractive display, What about the kitchen sink It’s hidden away behind an archway which leads into a small scullery. Here there’s a second cooker and — in the best farmhouse tradition — a huge walk-in larder for all food storage.

Compared with Extract 1 the room described in Extract 3 appears to().

A.be more comfortable

B.be more colourful

C.contain more furniture

D.possess a greater variety of style
