Answer:
2) Peristalsis is a series of muscle contractions. These contractions occur in your digestive tract. Peristalsis is an automatic and important process. It moves food through the digestive system.
3) Refractive index = Speed of light in vaccum / Speed of light in water. It is denotes as n = c / v, v = c / n= 3 × 10^8 m/s / (1.33) = 2.25 × 10^8 m/s. Therefore, refractive index of the water can be measure by the Speed of light in water is 2.25 × 10^8 m/s.
