Based on the simple blackbody radiation model described in class, answer the following question. The planets Mars and Venus have
Lera25 [3.4K]

Answer:

The extent of greenhouse effect on mars is G_m =  87 K  

Explanation:

From the question we are told that

     The albedo value of Mars is  A_1  = 0.15

      The albedo value of Mars is  A_2  = 0.15

       The surface temperature of Mars is  T_1 = 220 K

        The surface temperature of Venus is  T_2 = 700 K

          The distance of Mars from the sun is d_m = 2.28*10^8 \ km = 2.28*10^8* 1000 = 2.28*10^{11} \  m

          The distance of Venus from sun is  d_v = 1.08 *10^{8} \ km = 1.08 *10^{8} * 1000 =  1.08 *10^{11} \ m

       The radius of the sun is R = 7*10^{8} \ m

        The energy flux is   E = 6.28 * 10^{7} W/m^2

The solar constant for Mars is mathematically represented as

 

          T = [\frac{E R^2 (1- A_1)}{\sigma d_m} ]

Where \sigma is the Stefan's constant with a value  \sigma = 5.6*10^{-8} \ Wm^{-2} K^{-4}

So substituting values

         T = \frac{6.28 *10^{7} * (7*10^8)^2 * (1-0.15)}{(5.67 *10^{-8}) * (2.28 *10^{11})^2)}

          T = 307K

So the greenhouse effect on Mars is  

           G_m =  T -  T_1

           G_m =  307 - 220

          G_m =  87 K

Which of the following is a characteristic of electromagnetic waves? (2 points)
Mashutka [201]

Answer:

Electromagnetic waves are transverse waves, similar to water waves in the ocean or the waves seen on a guitar string. This is as opposed to the compression waves of sound. As you learned in Wave Motion, all waves have amplitude, wavelength, velocity and frequency.Feb 15, 2016
