Хорошо, давайте решим эту задачу по шагам, чтобы ответ был понятен.
Для начала, нам дано, что через блок массой 400 г пропущены две массы: 100 г и 140 г. Нам нужно найти суммарную массу этих двух масс.
Чтобы найти суммарную массу, нужно сложить эти две массы. Давайте это сделаем:
100 г + 140 г = 240 г
Итак, суммарная масса двух масс равна 240 г.
Теперь нам нужно найти, на сколько масс блока увеличилась после прохождения этих двух масс. Для этого нужно вычесть из суммарной массы две массы, которые были пропущены через блок.
400 г - 240 г = 160 г
Итак, масса блока увеличилась на 160 г после прохождения этих двух масс.
