Why is it important that the mouth and stomach are near the start of the digestive system? thx

Answers

Answer 1

Answer:

Answer: To complete the process of digestion after the food is ingested by mouth.

Explanation:

The food that we eat is ingested by mouth and here the mechanical degradation of food takes place. This breaks down the food into smaller pieces.

Mouth also contains the enzyme that is responsible for the digestion of starch.

Then the food from the mouth reaches the stomach where various types of digestive juices and enzymes are secreted to digested the food.

Hence, mouth and stomach must be near in the digestive system.

Answer 2

Answer: Because the mouth breaks down the food and the stomach uses acid to break food down even more

Help Please!!!(a) What is the force of gravity between two 1170 kg cars separated by a distance of 28 m on an interstate highway?
___________ N

Answers

Force is the product of mass and acceleration. The Force between the two-car is 1.1646 x 10⁻⁷ N.

What is force?

Force can be defined as an influence that can change the motion of an object. It can be given by the formula,

F = m x a

Given to us

Masses of the car, m = 1170 kg

Distance between the car, d = 28 m

We know that according to the force of gravity,

$F = G(m_1m_2)/(d^2)$

G = gravitational constant (6.67 × 10⁻¹¹ N·m²/kg²),

m₁ = mass of object 1

m₂ = the mass of object 2

d = distance between two objects

Substitute the values,

$F = (6.67 * 10^(-11))(1170 * 1170)/(28^2)\n\nF = 1.1646 * 10^(-7)\ N$

Hence, the Force between the two-car is 1.1646 x 10⁻⁷ N.

Answer:

$1.16\cdot 10^(-7) N$

Explanation:

The force of gravity between two objects is given by:

$F=G(m_1 m_2)/(r^2)$

where

G is the gravitational constant

m1, m2 are the masses of the two objects

r is their separation

In this problem, we have

m1 = m2 = 1170 kg is the mass of each car

r = 28 m is their separation

Substituting,

$F=(6.67\cdot 10^(-11) )((1170 kg)^2)/((28 m)^2)=1.16\cdot 10^(-7) N$
