Which structures allow for the removal of wastes from the developing fetus?

castortr0y [4]

The fetus relies upon its mother as it develops. These are some of the things it needs:

<span>protection against knock and bumps, and temperature changes oxygen for respiration nutrients (food and water) </span>

The developing fetus also needs its waste substances removing.

The fetus is protected by the uterus and the amniotic fluid, a liquid contained in a bag called the amnion.

Light travels at 3. 0 × 108 m/s in a vacuum and slows to 2. 0 × 108 m/s in glass. What is the index of refraction of glass?.

Sergio039 [100]

The required value of the index of refraction of glass is 1.5.

Given data:

The speed of light in a vacuum is, $c = 3.0 \times 10^{8} \;\rm m/s$ .

The speed of light in a glass is, $v = 2.0 \times 10^{8} \;\rm m/s$ .

Light has the tendency to travel from one medium to another, then the difference between the speeds of light in various mediums is determined by a term, known as the index of refraction. The mathematical expression for the index of refraction of glass is,

n = c / v

Solving as

$n = \dfrac{3.0 \times 10^{8}}{2.0 \times 10^{8}}\\\\n = 1.5$

Thus, we can conclude that the required value of the index of refraction of glass is 1.5.
