How might spontaneous generation be possible in a reducing environment? Question options: The reducing environment was created b

y the abundance of methane, which contains carbon. Because all life is organic, and organic molecules are all carbon-based, these molecules were the source of the spontaneous generation of life. Without oxygen, biological molecules, such as amino acids do not easily break down. As a result, they could have formed a "soup" of organic molecules in the oceans of the past, allowing spontaneous generation to occur. The concentration of nitrogen in the atmosphere created this reducing environment. Because nitrogen is present in amino acids, nucleic acids, and lipids, this environment favored conditions that eventually formed life through spontaneous generation. With high concentrations of carbon dioxide, biological molecules could have performed photosynthesis and pumped oxygen into the air in sufficient amounts over about 2 billion years, making spontaneous generation possible.

Using Rayleigh's criterion, calculate the diameter of an earth-based telescope that gives this resolution with 700 nm light.
pogonyaev

Complete Question

Due to blurring caused by atmospheric distortion, the best resolution that can be obtained by a normal, earth-based, visible-light telescope is about 0.3 arcsecond (there are 60 arcminutes in a degree and 60 arcseconds in an arcminute).Using Rayleigh's criterion, calculate the diameter of an earth-based telescope that gives this resolution with 700 nm light

Answer:

The diameter is  D = 0.59 \  m    

Explanation:

From the question we are told that

      The best resolution is  \theta  =  0.3 \  arcsecond

       The  wavelength is  \lambda  =  700 \  nm =  700 *10^{-9 } \  m

       

Generally the

         1 arcminute  = >  60 arcseconds

=>      x arcminute =>   0.3 arcsecond

So

       x =  \frac{0.3}{60 }

=>    x = 0.005 \  arcminutes

Now

         60 arcminutes  =>  1 degree

          0.005 arcminutes = >  z degrees  

=>       z =  \frac{0.005}{60 }

=>      z =  8.333 *10^{-5}  \ degree

Converting to radian  

           \theta  = z =  8.333 *10^{-5}  * 0.01745 = 1.454 *10^{-6} \  radian

Generally the resolution is mathematically represented as

            \theta  =  \frac{1.22 *  \lambda  }{ D}

=>    D =  \frac{1.22 * \lambda }{\theta }

=>     D =  \frac{1.22 * 700 *10^{-9} }{ 1.454 *10^{-6} }    

=>     D = 0.59 \  m
