Ymorist [56]
Hello!

<span>The air inside the building is easily pressed out the windows because the air is composed of widely spaced molecules in the gas phase. 

The word "gas" was created by the Netherlandish scientist Jean Baptista van Helmont from the Latin word "chaos". The gas phase consists of molecules with high kinetic energy, that adopt the shape of the container and tend to expand.  The molecules are essentially free, and the gravitational pull on them is negligible.

The state highway patrol radar guns use a frequency of 8.66 GHz. If you're approaching a speed trap driving 35.0 m/s, what frequ
otez555 [7]

Answer:

The frequency shift detected is \Delta  f  =1010.3 Hz

Explanation:

From the question we are told that

    The normal frequency of the state highway patrol radar guns f = 8.66 GHz =   8.66 *10^{9} \ Hz

     The speed of approach is v  =  35 .0 \ m/s

       

Now the frequency measure by the the state highway patrol radar guns as your car approaches is mathematically represented as

        f_n  =  f (1 + \frac{v}{c} )

Where c is the speed of light which a has constant value of

     c =  3.0 *10^{8 } \ m/s

  Now

       f_n - f  =  \frac{fv}{c} )

=>    \Delta  f  =   \frac{fv}{c}

substituting values

        \Delta  f  = \frac{ 8.66 *10^{9} *  35}{3.0 *10^8 }

        \Delta  f  =1010.3 Hz
