1. if the diameter of the sun and the earth are 1.4* 106 m and 1.275 * 107..compare these two.
  2. the size of red blood cell is 0.000007 m and the size of plant cell is 0.00001215 m ..compare these two

please solve these...!! ^_^

(1) 

Given : Diameter of sun = 1.4 × 106 m

and Diameter of earth = 1.275 × 107 = 1.275 × 10 × 106 = 12.75 × 106

 

⇒ Diameter of sun : Diameter of earth = 1.4 × 106 : 12.75 × 106

 

 

⇒ Size of blood cells : Size of plant cells = 7 × 10–6 : 12.15 × 10–6
