I.有同学利用如图所示的装置来验证力的平行四边形定则:在竖直木板上铺有白纸,固定两个光滑的滑轮A和B,将绳子打一个结点O,每个钩码的质量相等,当系统达到平衡-时,根据钩码个数读出三根绳子的拉力TOA、TOB和TOC,回答下列问题:

(1)改变钩码个数,实验能完成的是______

A.钩码的个数N1=N2=2,N3=4

B.钩码的个数N1=N3=3,N2=4

C.钩码的个数N1=N2=N3=4

D.钩码的个数N1=3,N2=4,N3=5

(2)在拆下钩码和绳子前,应该做好三个方面的记录:

______;

______;

______.

II.有两组同学进行了如下实验:

(1)甲组同学器材有:电源,滑动变阻器,电流表A1(0-200mA,内阻约11Ω),电流表A2(0-300mA,内阻约8Ω,定值电阻R1=24Ω,R2=12Ω,开关一个,导线若干.为了测量A1的内阻,该组同学共设计了下图中A、B、C、D四套方案:

其中最佳的方案是______套,若用此方案测得A1、A2示数分别为180mA和270mA,则A1的内阻为______Ω.

(2)乙组同学将甲组同学的电流表A1拿过来,再加上电阻箱R(最大阻值9.9Ω),定值电阻R0=6.0Ω,一个开关和若干导线用来测量一个电源(电动势E约为6.2V,内阻r约为2.1Ω)的电动势及内阻.请在图2方框中画出设计电路图.

单项选择题

While some international couriers are showing signs of exhaustion, EMS (Express Mail Service), the generic name for the courier services of post offices, seems to be finding its stride. Known as Datapost in Britain, as Chronopost in France, and as Al-Barid al-Mumtaz in Saudi Arabia, EMS is now second in the international courier business (jointly with TNT Skypack). Last year it delivered 5.6 million items, weighing less than 20 kilograms each, across borders. That and its annual growth rate of around 5 percent have worried DHL, the market leader, enough for it to counter-attack in the Courts.
On October 26, a Dutch judge ruled against DHL on all three counts filed against the Dutch post office: that the three-initial name was too close to DHL’s; that the orange lines in the EMS logo were too similar to DHL’s dark red ones; and that the claim to the widest route system in the world was unfounded. DHL has threatened the Swiss post office with similar action, but it may reconsider after the Dutch ruling.
EMS has some advantages over the private couriers. One is a dense ready-made network of offices, especially in Europe, the avowed target area of the private couriers. Another advantage is a long tradition of working with customs authorities. In a business where minutes count, it pays to have good friends at customs. That advantage particularly irritates the private couriers because there is no legal way to combat such unquantifiable coziness.
The private courier services are also annoyed because in countries like Switzerland and Italy, where the post office is officially a monopoly, they pay it a fee. In Switzerland DHL says it pays more than SFr lm ($708,000) "to the competition" each year. In France the couriers have won a battle for exoneration.
Although governments are under little pressure to keep prices artificially low, EMS is often cheaper than the private couriers, but not always. A recent test in Britain(on a domestic route)showed Datapost about halfway between the least and the most expensive, but gave it full marks for speed and service.
Each national EMS is free to set its rates and follow its own rules on things like bulk discounts. The Universal Postal Union, based in Berne, determines how costs and revenues are split between sending and receiving countries, and standardizes procedures. More than 100 postal administrations have linked into the system — and more are coming, including Russia’s. That makes the feisty EMS particularly happy since its rivals have not been allowed to serve anywhere in Russia.
