透過率が0.6っておかしいですよね……。 何が違うのでしょうか…… 回答よろしくお願いいたします。 ランベルトベールの法則です

SD課題 8.1口ある化合物の1.00×10 溶液の吸収度測定 (セル光路長 1.00 cm)を行ったとこ mol/L ろ、400mmの吸収度が、 0.500であった。 a) この波長のモル吸収係数を求めよ。 式は、以下を使う。 &cd=A+ 1.00×10mol/Ld:1.00cm、 A:0.500 とすると、以下のように表せる。 g×100×10-mol/L×1.00cm=0.500 0000 100006=5.0×10+t よって、モル吸収係数とは 5.0×10mol L-cm-1だとわかる。 bにの試料セルを透過した光のBlank 溶液を透過した光に対する割合を求めよ。 □透過率は T で表すことが出来る。以下に透過率の表し方を記載する。 IDは入射光の放射発散度、Iは試料を通過した光の放射発散度である。 また、 Lambert-Beer の法則を以下に示す。 T=14 I. log (1/1)=ecd=A ここで、透過率Tのほうは、 1. が分子に来ているが、 吸光度 A のほうはIが分母に来てい る。このため、透過率T と吸光度Aの関係は以下のように表せる。 ~log (Ⅰ/I.)=-legl=&cd=A また、この式は、 自然対数を使って表すと以下のように表せる。 A=InTIn(1/1.) この式とLambert-Beer の法則を合わせると、以下のように表せる。 ← T=e^( 8 cd)+ ここに、e: 5.0×10mol-c-1、c: 1.00×10mol/L d:1.00cm を組み合わせると 以下のように、透過率 Ⅰ を求めることが出来る。 T=e^(-5.0×10mol-cm-1×100×10-mol/L ×1.00cm) =0.60653065974 0.60~

問1 英文に文化は農業にシフトしたってあったから、選択肢③の狩猟や採集に加えてっていうのがひっかかったんですが農業にシフトしたのはseveral cultureだからでしょうか?それとも農業にシフトしたっていっても完全にはシフトしてないからですか??

You are going to read the Then just 12,000 years ago, several cultures shifted from hunting and migrating to other parts of the globe about 100,000 years ago.

The next 1,700 years were marked by the growth and conquest of empires, global navigation and exploration.
