Ngā Raru Whakaoti i roto i te Ahupūngao Taketake

Te wā o te korekore mō ngā matūriki – ngā raruraru me ngā otinga

1. E rua ngā pōro e honoa ana e te tokotoko, e whakaaturia ana i te pikitia i raro nei. Kaua e aro ki ngā tokotoko. papatipu. Ko te taumaha o te pōro P he 600 karamu, ā, ko te taumaha o te pōro Q he 400 karamu. He aha te Tuhinga o mua o te pūnaha mō AB?

Mōhiotia:

Ko te tuaka hurihuri ko AB.

m_p = 600 karamu = 0.6 kg, m_q = 400 karamu = 0.4 kg

r_p = 20 henimita = 0.2 m, r_q = 50 henimita = 0.5 mita

E hiahiatia ana: Te wā o te korekore o te pūnaha
