Answer:

Natural selection leads to evolution due to the way reproduction works. In the example of European moths during the industrial revolution, we can see this clearly. When the industrial revolution was going, there was more pollution, hence darkening the skies and leaving ash. Moths, which before were white with occasional black spots dominated the area until pollution effected their environment. Whiter moths were eaten by bird who could easily see them against the black trees and skies. These moths could no longer reproduce, they were dead. Moths with more black could survive longer to reproduce because they were harder to see. As time went along, the moths turned mostly black, showing an example of evolution.

The rest of the plasma fluid is reabsorbed into the blood stream. This comprises of the nutrients and water. The unwanted materials i.e. solutes, water etc do concentrate to form the urine and the other filtrated products are therefore reabsorbed.

What is the period of a satellite in a circular orbit just above the surface of the Moon? The Moon’s mass is 7.36 × 1022 kilogra
Tanya [424]

Answer:

<h3>C. 6.50 x 10^3</h3>

Explanation:

The satellite revolves around moon due to centripetal force which is provided by gravity  in this context so we can equate gravity and centripetal force.

                  mrw^{2} = \frac{GMm}{R^{2} }

where, m is mass of satellite

           M is mass of moon

           ω is angular velocity

           G is Universal gravitational constant

            R is the radius of moon

from the above equation we get ω as,

                          w=\sqrt{\frac{GM}{R^{3} } }

                               T = \frac{2\pi }{w}

                                   T= 2\pi \sqrt{\frac{R^{3} }{GM} }

      here M = 7.36 X 10^22

               R = 1.738 X 10^6

               G =6.67 X 10^-11

              T= 2X3.14 \sqrt{\frac{(1.738 X 10^6)^{3} }{6.67 X 10^-11 X 7.36 X 10^22} }

                      T= 6.50 X 10^3 seconds
