この大問7の(3)の①の解き方と(5)の①の解き方が分からないので誰か教えて頂けますか(_ _) ちなみに答えは(3)30倍と(5)100Ωです

LED(発光ダイオード)と豆電球の明るさを比較するため、次の実験を行った。 次の各問いに答えなさい。 7 実験 [1] 図1のような回路A,Bを用意し, LEDと豆電球に3Vの電圧を加えてそれぞれ点灯させたところ, LEDの方が豆電球より明るく点灯した。 このときのLEDと豆電球に流れる電流の強さを調べた ところ, LEDが20mA, 豆電球が270mA であった。 [2] LEDに加えている電圧はそのままにして、豆電球に加えている電圧を3Vから1Vずつ上げて, 豆 電球の明るさをLEDの明るさに近づけていくと, 5Vで同じになった。 表は、このときの実験結果につ いてまとめたものである。 回路A 図1 A CHO - + 000+ ■会員 電圧計 電圧[V] 豆電球の明るさ 電流の強さ [mA] LED ISTRUOJ 電源装置 000 JOA 電流計 saksavera esc 3 LEDより暗い 270 回路B -0000+ M ■■ 電圧計 4 LEDより少し暗い 320 (3) 次の文の ① に当てはまる数値を書きなさい。 また, ② の { ア, イから選びなさい。 豆電球 MORAJEVOHB 下線部の値を正確に読むためには,回路Aでは図2① {ア 50mA イ 500mA ウ 5A} の一端子とつなぎ, 回路Bでは2 ② {ア 50mA イ 500mA ウ 5A} の一端子とつなぐとよい。 電源装置 1+ 8888 M 電流計 (1) 実験 [1] において, LEDに3Vの電圧を加えたときのLEDの抵抗は何Ωか、書きなさい。 図2 (2) 図2は実験 [1]で用いた電流計の一部を示したものである。 次の文の①,②の子に当て ちはまる最も適当なものを、 それぞれア~ウから選びなさい。 ERASJEVE SO 5 LEDと同じ明るさ 360 ARMAD JII 150mA 500mA 5A +D.C. }に当てはまるものを 電気エネルギーから光エネルギーへの変換効率を, LEDと豆電球で比較するためには、 明るさが同じときの消費電力を比較するとよい。 実験 [2] において, LEDと豆電球の明る さが同じとき、豆電球の消費電力がLEDの ① ] 倍となることから, 変換効率は, 豆電 球の方が② {ア 高い イ低い}といえる。

コミニケーション英語2 Lesson7 Section1 下のQuestion Anser Practiceの解説が知りたいです!

Communication English II Lesson 7 Encouraging Song Section 1&2 Reading Passage Section 1 There are many songs that help people overcome sadness or troubles. Makenaide may be one of them. This song has been encouraging many people for a long time. The lyrics of Makenaide were written by Sakai Izumi, the vocalist of ZARD. It became a hit in 1993. The following year, it was adopted as the theme song for the National High School Baseball Invitational Tournament. Some schools have also been using this song for graduation ceremonies. When the Great Hanshin-Awaji Earthquake occurred in 1995, this song was often aired. Many people were able to recover their spirits by listening to it. The song also cheered people up after the Great East Japan Earthquake in 2011. Unfortunately, Sakai passed away in 2007. However, this song is still popular today. Section 2 What makes this song so attractive? The answer may be in its lyrics. The song has a message of hope for everyone. Let's take a look at the first refrain. Sakai left a piece of paper on which she wrote the lyrics. It shows that she changed a part of them. She replaced the words "Don't stop until the end" with "Keep on running until the end". She may have thought that this sounded more positive. Handout Reading No.15 Text p.94-97 She changed this part while she was actually recording the song. "Which words communicate better?" was the question she always had in her mind. She always searched for words that would encourage people. Don't give up! Just a little farther 負けないで もうすこし Keep on running until the end 最後まで走りぬけて Even though we may be apart どんなに離れてても I'll stand by you with all my heart 心はそばにいるわ Follow the dream you'll catch in the end 追いかけてはるかな夢を 1.
