想請問D的解釋

凡尼爾(C. B. van Niel,1897 ~ 1985)於1920 年代證實綠色細菌、紫硫菌與綠硫菌 在光照情形下,可將硫化氫(HS)氧化成硫(S)[式1〕。他也發現紫硫菌等細菌可氧 化某些有機化合物,以作為氫的提供者。與綠色植物光合作用的反應式〔式2〕相比之下, 凡尼爾推論光合作用所產生的 O, 來自水而非二氧化碳。魯賓(Ruben)等人於 1941 年用 同位素分別標定 C'°O, 與 HO 進行實驗,證實此推論為正確的。 200 (g),00 EX_2H,S + CO,→2S + (CH,O) + H, ....

金屬球殼 屏蔽效應的問題 我想請問這類題目這麼思考 若它沒有接地我還能理解因為外部電場與感應電場抵銷所以金屬球殼內部電場依舊是零 但若接地我就無法理解了

DBUY B為絕緣體時,均不帶電。 設有一接地之金屬球殼,殼內以絕緣線繫一正電荷+Q於球心。如將另一正電荷+q由遠處 移近球殼(如圖),則下列那些現象會發生? (A)球殼鄰近+q之一面會帶負電,球殼另一端則會帶正電。 (/(B)電荷+Q會受到+q之排斥力。 (C)球殼與+q之間會產生吸引力。 (D)球殼內部之電場因+q之移近而改變。 (E)將電荷+q移近球殼時須以外力對+q做正功。 图:(C) 静电 o 0 O.V. +Q +9 het h OUT
