如图所示,理想变压器原、副线圈的匝数比为k,输出端接有一交流电动机,其线圈的电阻为R。将原线圈接在正弦交流电源两端,电动机恰好能带动质量为m的物体以速度v匀速上升,此时理想电流表的示数为I。若不计电动机的机械损耗,重力加速度为g,则下列说法正确的是

[ ]

A.副线圈的输出功率为mgv

B.原线圈两端的电压为kIR

C.原线圈中的电流为kI

D.副线圈两端的电压为IR+

Most lives saved from sinking ferryCao Min couldn’t believe she was experiencing exactly what she had seen years ago in the film “Titanic”.

Cao and her two children from Anhui Province were traveling on board the “Liaoludu 7”on February 22.They were among the first people on the ship who were rescued by lifeboats. Cao’s one-year-old son was the youngest passenger on board.

The “Liaoludu 7”was traveling in the Bohai Straits(渤海海峡)from Lushun in Liaoning Province to the port city of Longkou in Shandong Province. It suddenly lost its power at 2:30 pm and tilted(倾斜)on its side. With 81 people on board, the ferry(渡船)began to sink.

“I was so scared that my legs couldn’t move forward. They kept shaking even when I was asked to jump onto a “ lifeboat.” Cao recalled.

Upon receiving the urgent appeal, China Marine Search and Rescue Center(中国海上搜救中心)immediately informed the State Council(国务院).The center sent eight lifeboats to the sinking ship and asked for help form the Ministry of Agriculture, the Navy and nearby fishing boats.

After more than four hours of fighting against strong winds and freezing ocean water, the passengers were recovered. All but four survived. These four died after spending too long in the freezing waters, according to a spokesperson for the Beijing-based center.
