The human body is composed mostly of water. Why does the Moon overhead cause appreciably less tidal effect in the fluid compartment of your body than a 1-kg melon held over your head does?

Respuesta :

Answer:

The force is inversely proportional to the square of radial distance and the mass of the lemon is compensated.

Explanation:

  • It is true that our body is composed mostly of water (precisely 75% of the body mass) which is influenced by the gravitational forces. This gravitational force in the water bodies cause tides.

We know that mathematically gravitational force is given as:

[tex]F=G.\frac{M_1.M_2}{R^2}[/tex]

where:

R = radial distance between the masses

we observe that:

[tex]F\propto\frac{1}{R^2}[/tex]

The force is inversely proportional to the square of radial distance.

  • And the radial distance between the moon and a human on the earth is much greater than the distance between a lemon of low mass on the head of a human.
