Here’s my work to your question. I used Newton’s Second Law and a kinematics equation to arrive at the answer.
 
        
        
        
Answer:
comparing the anatomy of organisms
Explanation:
Basically, Rocks are the solid evidence used to date the earth. 
 Due to the changing in the genetic make up of organisms,the anatomy of organisms is not a reliable evidence to date the earth.
 
        
             
        
        
        
 Answer:
Explanation:
a ) The earth rotates by 2π radian in 24 x 60 x 60 s 
so angular speed ( w )  = 2π / (24 x 60 x 60)  = 7.268 x  10⁻⁵ rad / s 
b ) Linear speed of city of Arlington ( v )  = w r = w R Cosλ where R is radius of the earth and λ is latitude .
v = 7.268 x 10⁻⁵ x  6.371 x 10⁶ cos 32.7357 
389.5 m /s
acceleration = w² r = w² R Cos 32.7357
= (7.268 x 10⁻⁵ )² x 6.371 x 10⁶ x cos 32.7357
=283.08 x 10⁻⁴ m/s² 
 c) velocity ratio =
 w r /w R =
 R cos 32.73/ R  
= Cos 32.73
 = 0.84 .
