Mechanical digestion is where the food is physically broken down into smaller pieces, such as in the mouth. Chemical digestion is where the food us chemically broken down into subtomic particles , starting with the saliva in the mouth and continuing throught the small intestine.

Calculate the pressure exerted by mercury column of 76cm high at its bottom. Given that the density of mercury is 13600kg/m³ and

raketka [301]

Answer:

P = 101292.8

Explanation:

Use

Pressure p = H D g

H = height ( in metric)

D = density ( in metric )

g = gravity

H = 76 cm = 0.76 m

D = 13600 kg/m3

And g = 9.8

P = HDg

= 0.76× 13600×9.8

= 101292.8 pascal

Or = 1.012928 × 10^5

Describe the relationship between the length and period of a pendulum in the language of direct proportions

Wittaler [7]

The period of the pendulum is directly proportional to the square root of the length of the pendulum

Explanation:

The period of a simple pendulum is given by the equation

$T=2\pi \sqrt{\frac{L}{g}}$

where

T is the period

L is the length of the pendulum

g is the acceleration of gravity

From the equation, we see that when the length of the pendulum increases, the period of the pendulum increases as the square root of L, $T\propto \sqrt{L}$ . This means that

The period of the pendulum is directly proportional to the square root of the length of the pendulum

From the equation, we also notice that the period of a pendulum does not depend on its mass.
