(2)でN=0が含まれるのはなぜですか? ※円運動

周期の式「T 基本例題 37 鉛直面内の円運動 図のように、なめらかな斜面と半径rのなめらか な半円筒面が点Aでつながっている。 質量mの小 球を点Aからの高さんの斜面上の点Pで静かには なしたところ、小球は面にそって運動し,最高点B を通過した。 重力加速度の大きさをgとする。 (1) 点Bを通過するときの小球の速さを求めよ。 (2) 点Bを通過するために, hが満たすべき条件を求めよ。 最高点Bで受ける垂直抗力が0以上であれば, 小球は点Bを通過できる。 m-N-mg=0 (1) 点Aを重力による位置エネルギーの 基準とし,点Pと点Bの間で力学的 エネルギー保存則を立てると 0+mgh=/mv²+mg•2r よってv=√2g(h-2r) (2) 点Bで小球が円筒面から受ける垂直 抗力の大きさをNとする。 小球とと もに運動する観測者から見ると, 点 Bにおいて小球には重力, 垂直抗力 遠心力がはたらき, これらがつりあ っている。したがって よって h v² r =m N=m- ・mg 2g(h-2r) r 2h = (27-5) mg mg 60,161 きはどちら (4) この円運動 B V 146 向心 答えよ。 (1) なめら (2) 回転す (3) 水平 (4) 地球 (5) 水平 (1) m.

リン酸緩衝液って何ですか?また、結果から何が分かるんですか?教えて下さると嬉しいです🙇‍♀️

方で答えよ (例 ATP)。 36. 細胞内の酵素による酸化還元反応 ハトの胸筋に含まれる酸化還元酵素である コハク酸脱水素酵素の活性を調べる実験をメチレンブルーを指示薬として行った。 実験には,図のガラス管を用いて, 主室にハトの胸筋をリン酸緩衝液とともに破砕 主室 ハト胸筋を破砕した懸濁液(mL) 0.02% メチレンブルー溶液(mL) | 10% コハク酸ナトリウム溶液(mL) 10% マロン酸ナトリウム溶液(mL) リン酸緩衝液 (mL) 副室 実験1 実験2 実験3 実験4 5 0.5 1 0 1 20.5 0 1.5 2. 0 0 1 1 20 [16 横浜国大〕 副室 アスピレーターへ 主室 した懸濁液を入れ, 副室には表に示すように試薬を入れた。 アスピ レーターを用いて器具内を脱気してから副室部分を回転して外気を 遮断した後,主室の抽出液と副室の試薬を混合した。 すべての実験において混合直後 の液の色は青色であった。このガラス管を37℃に保温して色の変化を観察した。実験 1と実験2の結果は同一であり、時間とともにしだいに青色が薄くなり, 10分で完全に 青色が消失した。 なお, マロン酸はコハク酸脱水素酵素の競争的阻害剤としてはたらく。 (1) この実験に用いたガラス管を何というか。 (2) 実験1と同様の操作をガラス管内の脱気をせずに行うと,どのようになるか。 (3) 実験3において,青色が消失するまでの時間は実験1と比べてどのようになると推 測されるか。 (4) 実験4でも青色の消失が観察された。このとき青色が消失するまでの時間は実験1 [16 北里大 改〕 と比べてどのようになると推測されるか。 第3章 代 謝 47
