物理基礎の質問です 図aでは運動方程式、図bでは力のつりあいの式を立ててますが、なぜ運動方程式の物体Bについての式ではma=T-mgでT=mg▶︎ma=mg-mg▶︎ma=0にならないんですか？ T=mgでつりあってるんじゃないんですか？

The rest of the classが「クラスの残りの生徒」になるのも理解できるんですけど、、「授業の休憩」ってならないんですかね、？

classとclassesの違いはなんですか？

In my opinion, we should be promote equality and recognition of educational background. Now, stady devide continue to spread further. For example. TV problem I have watched showed a poor boy do in South Africa The boy who working housewort not have time enough to go and money enough to do To the school 26 I proved that there are many childrench would like to go to school. I believe that everyone , but they cannot do should understand those situation in which children suffer from having little money. Moreover, put into we. practice such as donating money and volunteer that we help them to study. Through those experiences, educational background may close to equality 11年

photos token of me actively providing instruction in OPAL classroomを「OPALの教室で精力的に指導している私の画像」 という訳し方を教材でしていたのですが、これはどういう文構造なのでしょうか？？

この文章の文構造はどのようになっているのでしょうか？ to enrollは何と並列関係にあるのですか？？
