Which of these will have the same units of pressure is multiplied by area? Velocity time force or pressure
choli [55]

Considering the definition of pressure, force will have the same units of pressure is multiplied by area.

<h3>What is pressure</h3>

Pressure is defined as the force exerted per unit area.

In this way, for the same force, the pressure is inversely proportional to the surface: this means that, for the same force, the smaller the surface, the greater the pressure exerted and the more the body will be deformed.

That is, pressure is defined as the force exerted perpendicularly on a surface and is expressed mathematically as:

Pressure=\frac{Force}{Area}

In the International System of Units, the unit of pressure is the pascal (Pa). One pascal is the pressure exerted by a force of 1 N distributed over an area of ​​1 m².

Then, the definition of force can be expressed as:

Force= Pressure× Area

<h3>Summary</h3>

In summary, force will have the same units of pressure is multiplied by area.

A perceived increase in the volume of sound is best explained by ________.
tatiyna

Answer:

A. an increase in the height of the sound wave

Explanation:

Volume of the sound is measured by its intensity

So here we know that

intensity is directly depends on the square of the amplitude of the sound wave

so here as intensity depends on the loudness of the sound given as

L = 10 Log(\frac{I}{I_o})

so here as the loudness of sound will increase then the intensity will increase and hence the amplitude of the sound will also increase

So correct answer will be

A. an increase in the height of the sound wave

If this did not happen, what would be the approximate force on an eardrum of area 0.22 cm2 if a change in altitude of 1500 m tak
jeyben [28]

Complete Question

When you ascend or descend a great deal when driving in a car yours ears "pop," which means that the pressure behind the eardrum is being equalized to that outside. If this did not happen, what would be the approximate force on an eardrum of area .50 cm2 if a change in altitude of 950 m takes place?

Answer:

The value is F    = 0.60 \  N

Explanation:

From the question we are told that

   The area of the ear drum is  A = 0.5 \  cm^2 = 0.50 *10^{-4} \  m^2

    The change in altitude is  \Delta d  = 950 \  m

Generally the change in pressure is mathematically represented as

       \Delta P = \frac{F}{A}

This can also be mathematically represented as

      \Delta P = \rho * g *  \Delta d

So

       \frac{F}{A}     = \rho * g *  \Delta d

=>    F    = \rho * g *  \Delta d  *  A

=>    F    = \rho * g *  \Delta d  *  A

Here \rho is the density of dry air with value  \rho =  1.29 \ kg /m^3

So

     F    = 1.29 * 9.8 *  950  *  0.50 *10^{-4}

=> F    = 0.60 \  N
