Answer: :Total distance to be travelled = 4.4 km
= 4400 m
Diameter of wheel = 70 cm = 0.7 m
Radius of wheel= 0.7 / 2 m
Circumference of wheel = 2 * pi *r
= 2* 22*0.7 / 7* 2
= 22*0.1
= 2.2 m
No. Of revolutions = Total distance / Circumference of wheel
= 4400 / 2.2
= 2000

Explanation:
The energetic particles coming from the Sun and Saturn's environment allow complex chemistry, such as formation of hydrocarbons and nitriles. The particles also generate a permanent haze around the satellite, rains of methane, winds, seasons Recently, lakes of hydrocarbons seem to have been detected on Titan's surface.
 
        
             
        
        
        
Cells divide for growth, to repair tissue damage, and because the nucleus can only control a certain size of cell.
