Where do cardiac muscle cells fit in a body-system hierarchy?

Worked method: Cardiac muscle cells form muscle tissue; tissue helps make the heart; the heart is an organ of the circulatory system.

Balance H₂ + O₂ → H₂O.

Worked method: 2H₂ + O₂ → 2H₂O. Both sides contain four H atoms and two O atoms.

Estimate light speed in water using n = 1.33 and c = 3.00 × 10⁸ m/s.

Worked method: v = c/n = (3.00 × 10⁸ m/s)/1.33 = 2.26 × 10⁸ m/s.
