48、下圖甲是某小組同學“測量小燈泡的電功率”的實驗電路圖,已知小燈泡的額定電壓為6V,正常工作時的電流約為0.3A.現(xiàn)有如下器材:電流表、電壓表、開關(guān)各一個,規(guī)格分別為“100Ω 2A”“50Ω l.5A”的滑動變阻器各一個、導線若干、電源(電壓為12V左右)一個。
(1)圖乙已連接了部分電路,請用筆畫線代替導線將電路連接完整。
(2)你認為該小組應(yīng)選用規(guī)格為 的滑動變阻器
(3)該小組同學選用了合適的滑動變阻器后閉合開關(guān),滑片P移到某一位置時記錄了第1組數(shù)據(jù):滑片P繼續(xù)向右移動,當小燈泡正常發(fā)光時.電流表示數(shù)如丙圖所示.請幫他們將電流表的示數(shù)記入表中空白處;當滑片P移到最右端時,小燈泡閃亮一下后熄滅,然后他們記錄了第3組數(shù)據(jù);從表中數(shù)據(jù)可知他們所用的電源電壓為 V,小燈泡的額定功率為 W。

47、某物理學習小組,針對同學中存在的有關(guān)斜面問題的一些疑惑,進行了實驗探究和理論探究活動.
[實驗探究]
將長度為l m的長木板的一端墊高,構(gòu)成長度一定高度可調(diào)的斜面(如右圖所示).用沿斜面向上的拉力F使重為10N的滑塊沿斜面勻速向上運動。完成斜面機械效率測量.下表呈現(xiàn)的是部分實驗數(shù)據(jù):

(1)疑惑一:“斜面的機械效率越高越省力嗎?”
請報據(jù)表中的實驗數(shù)據(jù),寫出正確的結(jié)論。
(2)疑惑二,“斜面傾斜程度越大拉力越大,滑塊受到的摩擦力也一定越大嗎?”
請進一步分析表中實驗數(shù)據(jù),寫出正確的結(jié)論:
簡述理由:
[理論探究]
(3)疑惑三。“滑塊受到的摩擦力是一個‘不可直接測量’量,能通過‘可測量’量求出摩擦力嗎?”
請根據(jù)已有的知識推導:對于傾斜程度不同的斜面,在拉力F作用下(拉力方向沿斜面向上或向下)使重為G的滑塊沿斜面勻速移動時,滑塊受到的摩擦力f的數(shù)學表達式(斜面的長L和斜面的高h均為“可測量”量)
