題目列表(包括答案和解析)

在物理學(xué)中,磁場(chǎng)的強(qiáng)弱用磁感應(yīng)強(qiáng)度(用字母B表示,國(guó)際單位是特斯拉,符號(hào)是T)來表示,磁感線越密的地方,磁場(chǎng)越強(qiáng),磁感應(yīng)強(qiáng)度B越大.

(1)在圖20中,甲為某磁極附近磁感線的方向和分布的示意圖,由圖可知,該磁極為 ▲ 極,若在l處放置一個(gè)小磁針,當(dāng)小磁針靜止時(shí),其指向應(yīng)是圖乙中的  ▲   .
(2)磁敏電阻阻值的大小隨磁場(chǎng)的強(qiáng)弱變化而變,圖丁是某磁敏電阻R的阻值隨磁感應(yīng)強(qiáng)度B變化的圖象,據(jù)圖線可知,磁敏電阻的阻值隨磁感應(yīng)強(qiáng)度B的增大而▲ .圖線沒有過坐標(biāo)原點(diǎn),說明  ▲  .
(3)王強(qiáng)設(shè)計(jì)了一個(gè)可以測(cè)量該磁敏電阻R的電路如圖丙所示,(其中磁敏電阻所處的磁場(chǎng)未畫出).將該磁敏電阻R放置在磁場(chǎng)中的位置某處,測(cè)出電阻后,利用R—B特性曲線可以讀出相應(yīng)的磁感應(yīng)強(qiáng)度.
①在圖甲磁場(chǎng)中1處,測(cè)得的數(shù)據(jù)如圖20表中所示,則該磁敏電阻的測(cè)量值為 ▲ Ω. 
②根據(jù)該磁敏電阻的R-B特性曲線可知,1處的磁感應(yīng)強(qiáng)度為   ▲    T.
③在實(shí)驗(yàn)過程中,僅將磁敏電阻從1處移至2處,其它條件不變,那么電流表的示數(shù)
▲   (填“增大”、“減小”或“不變”).
④依據(jù)上述方法獲得的磁感應(yīng)強(qiáng)度B的測(cè)量值與該點(diǎn)實(shí)際值存在不小的誤差,為盡可能準(zhǔn)確反映空間某點(diǎn)磁場(chǎng)的強(qiáng)弱,你認(rèn)為在選擇磁敏電阻時(shí)應(yīng)注意什么問題?

"who planted the trees from which those figs were picked?" "Why...why, I don't know."  
     "You see, sir," went on the old man "our forefathers (祖先) planted trees for us to enjoy, and I 
am doing the same for the people after me."
