Anasa scientist studies a moon rock whose mass is 9.30 kg and finds that it has an apparent mass of 6.30 kg when submerged in water.

This means the buoyancy or upward force is 3kg. Mass - buoyancy = apparent mass so 9.3 kg - 3 kg = 6 kg

Answer feldspar,quartz,mica and amphibole;

Unique question.well, using science, you cannot create or destroy even if you do eat yourself so you would not grow twice as big, nor would you disappear. you would stay the same but change states potentially, or at least change your appearance (obviously).hope this . keep up these unique questions.
