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

What is the purpose of control rods in a nuclear reactor
stellarik [79]

Answer:

Control rods are an important technology for maintaining the desired state of fission reactions within a nuclear reactor. They constitute a real-time control of the fission process, which is crucial for both keeping the fission chain reaction active and preventing it from accelerating beyond control.
