How is chewing food both chemical and physical?
BigorU [14]
It is both. 

<span>It is a physical change because when you chew your food you break it up into smaller pieces and are therefore changing its size and shape which are physical changes. </span>

<span>However, digestion begins in the mouth. When we chew our food, it mixes with enzymes from our saliva and begins to break down the food. Digestion is a chemical change.</span>

A high school physics student is sitting in a seat read-
Nataly_w [17]

The equilibrium condition allows finding the result for the force that the chair exerts on the student is:

  • The reaction force that the chair exerts on the student's support is equal to the student's weight.

Newton's second law gives the relationship between force, mass and acceleration of bodies, in the special case that the acceleration is is zero equilibrium condition.

            ∑ F = 0

Where F is the external force.

The free body diagram is a diagram of the forces on bodies without the details of the shape of the body, in the attached we can see a diagram of the forces.

Let's analyze the force on the chair.

            N_{chair} - W_{chair} - W_{student} = 0 \\ \\N_{chair} = W_{chair} + W_{student}

Let's analyze the forces on the student.

          N_{student} - W_{student} = 0  \\N_{student} = W _{student}

           

In conclusion using the equilibrium condition we can find the result for the force that the chair exerts on the student is:

  • The reaction force that the chair exerts on the student's support is equal to the student's weight.

What two factors determine the color of an object?
slamgirl [31]
<h3><u>Answer;</u></h3>

4. the material the object is made of and the color of light that strikes it

<h3><u>Explanation;</u></h3>
  • The color of an object is the wavelength of light that the object reflects, which is determined by the arrangement of electrons in the atoms of the material making the object.
  • <em><u>We could therefore say that the color of object depends on or is determined by the material making up the object as this determines the the wavelengths of light the object reflects. Lastly, the color of light source also determines the color of the object.</u></em>
