13. Műhold körpályán – gravitációs erő munkája

Amit a modell a teljes feladatsorról jelzettNumbering restarts in MÁSODIK RÉSZ (three optional essay topics 1-3, only one to be chosen) and in HARMADIK RÉSZ (computational tasks 1-4), so numbers 1-3 appear multiple times; see part_labels. No per-question point values are printed in the paper (only the final score table on page 16, items 420-429, which was excluded). Task 4 of the third part (page 15) was extracted as table objects (items 415-416) containing the question text, plus a figure; its exact internal structure should be checked manually. In third-part task 1, many small FIGURE items (301-327) are fragments of one illustration interleaved with the text. Repeated 'emelt szint' page headers were put in skip_items of the neighbouring questions.
