物理基礎、斜面上の運動の問題です （2）がわかりません 加速度が下方にはたらいているから、下方の力のほうがTより大きいと思って 5.0×9.8×1/2 − T をしたのですが、逆だったようなので理由を教えて欲しいです🙇‍♀️

NUTS $XOREO#OR LA (1) 42. 斜面上の運動 傾きの角が30° のなめらかな斜面上に質量 えて、物体を引き上げたり下ろしたりした。 重力加速度の大きさを 5.0kgの物体を置き, これに糸をつけ, 斜面に平行に上向きの力を加gle 9.8m/s²とする。 (1) 糸の張力の大きさが40Nのとき, 物体の加速度αはどの向きに何 大 m/s2 か。 (2) 物体の加速度が斜面下方に 1.9m/s2 のとき,糸の張力の大きさTは何 N か。 2 おから 30° 例題18

仮定法の範囲です 6〜21、20、24〜26の答え教えてください！ 解いたのであってるかみてほしいです。不正解の場合正しい回答もしりたいです🙇‍♂️

2段階目の電離の表がわからないのですが、 なぜ変化量は表のようになるのでしょうか？

138. 多段階電離 解答 ④ ²00. 解説 硫酸は2価の強酸であり、その電離は2段階に進行する。 HSO SO²+H+ H2SO4 → HSO4+H+ c[mol/L] 硫酸水溶液について, まず1段階目は完全に電離するので,そ の変化は濃度c を用いて次のように表される。 H2SO4 → HSO4- + H+ 0 + c(0 C C - (0 cl 0 [mol/L]. C [mol/L] 係数が同じならば 電離前 電離後 2段階目の電離度が α2 なので, HSO4-の電離は次のように表される。 HSO4 SO4- + H+ 電離前 C 0 C [mol/L] 変化量 -cα₂ + caz +ca₂ [mol/L) 電離後 c (1-α2) ca2 c+ca [mol/L] したがって, [H+]=c(1+α2) [mol/L] となり, ④ が該当する。 C+CX2(展しただけ) Ha 変化量はすべて等しい 比 GOOD
