<prompt> Bheka isigaba esingezansi bese uphendula umbuzo emva kwalokho ngolimi olufanayo nesigaba: I-Passage: v. Lesi sidingo esibalulekile yiso esihlukanisa i-vector engaguquguquki kunoma iyiphi enye i-triple yobukhulu obunenjongo ngokomzimba. Isibonelo, uma u-v equkethe i-x, y, kanye ne-z-izakhi zejubane, khona-ke u-v uyisixhumi esiphikisanayo: uma izixhumanisi zesikhala zeluliwe, zijikeleziwe, noma zihlanekezelwe, khona-ke izingxenye zejubane ziguqulwa ngendlela efanayo. Ngakolunye uhlangothi, ngokwesibonelo, i-triple equkethe ubude, ububanzi nokuphakama kwebhokisi elingunxande ingakha izingxenye ezintathu ze-vector engaqondakali, kodwa le vector ngeke ibe yi-contravariant, ngoba ukujikeleza ibhokisi akuguquli ubude, ububanzi nokuphakama kwebhokisi. Izibonelo ze-contravariant vectors zihlanganisa ukufuduka, isivinini, insimu kagesi, umfutho, amandla, nokusheshisa. Umbuzo: yiziphi izibonelo o vectors contravariant  <response>: ukufuduka, isivinini, inkambu kagesi, umfutho, amandla, nokusheshisa.
