問4について質問です なぜ極板を動かす前と後で極板2の電気量は保存されるのですか?独立してないですよね?

3 以下の説明文を読み, その後の問いに答えなさい。(配点 25) 図1に示すように, 一辺が a(m]の正方形の導体極板1, 2, 3を平行に置く。 極板1と極板2, および極板2と極板3の極板間隔はそれぞれ 2d [m] とする。 aはdより十分大きいとする。 また, 起電力 V.(V]の電池が図のように接続されている。 これらの極板は誘電率 Eo[F/m]の真空中に置か れ、最初,極板は帯電していない。スイッチSWは最初は開いた状態にある。 SW を閉じて十分時間が経過した後,再び SWを開いた。 解答は a, d, Vo éoの中から必要なも のを用いて表しなさい。 ただし, 点Eの電位を OVとする。 a 極板1 a 極板2 2d a SW 2d a 極板3 V。 E 図1 問1 極板1と2の間の電気容量 Cl2[F] を求めなさい。 問2 それぞれの極板1,2, 3に帯電した電気量 Qi. Qe Qs[C] を求めなさい。 正負の符号も付 けて解答しなさい。 問3 極板1と2の間に蓄えられた静電エネルギーU12[J]を求めなさい。 問 4 極板2を極板1の方向へ距離d [m] だけゆっくり移動させた。移動後の極板2の電位 1V3[V] を求めなさい。また, 極板1, 2, 3にそれぞれ帯電している電気量Q1, Qs Qs[C]を求めな さい。正負の符号も付けて解答しなさい。

ものすごく至急です💦今日授業で当てられそうなのですか答えが確実じゃなくて焦っています 答えだけでいいのでほんとうによろしくお願いします 根拠の場所あれば教えて欲しいです

次の英文を読み,下の問いに答えなさい。 We all know the saying “To err is human." And this is true enough. When somethine 80es wrong, the cause is overwhelmingly attributed to human error: airplane crashes (70 percent), car wrecks (90 percent), workplace accidents (also 90 percent), You name it, and humans are usually to blame, And once a human is blamed, the inquiry usually stops ans ISL stu an 止 there. But it shouldn'tー atleast not if we want to eliminate the error. S In many cases, our mistakes are not our fault, at least not entirely. For we all have certain biases" in the way we see, remember, and perceive the world around us, and these biases make us commit certain kinds of errors, Right-handed people, for instance, tend to turn right when entering a building, even though that may not afford the best route to take. And most of us, whether left- or right-handed, show a preference for the number 7 and the color blue. We are also so persuaded by our first impressions of things that we are reluctant to change our first answer on a test; yet many studies have shown we would be better off if we did exactly this. Qur expectations can shape the way we see the world and often the way we act in itas well, In one case, people encountered an unknown man and were later told his occupation. When they were told that the man was a truck driver, they said he weighed more%; when they were told he was a dancer, they said he weighed less. In another case, half the people in a restaurant were told their free glass of wine that night came from France; the other half were told their wine came from somewhere else. Not only did the second group eat less of their meals, but they headed for the doors more quickly. Farmers too show the same tendency. Farmers who believe in global warming, for instance, have been shown to remember temperatures as being warmer than those recorded in statistical tables, And what about farmers who do not believe in global warming? They remembered temperatures that were colder than those in the record books. What's important about these examples is not that we think a truck driver is fatter than a dancer or that temperatures are warmer than they used to be. What'simportant is that these effects occur largely outside of our consciousness; we're biased ー we just don't know we' re biased. Some of these tendencies are so strone that eyen_when_we do know
