The geosphere interacts with the hydrosphere when water causes rock to erode. The atmosphere provides the geosphere with heat and energy for erosion, and the geosphere reflects the sun's energy back into the atmosphere.
 
        
                    
             
        
        
        
Answer:
0.087 m
Explanation:
Length of the rod, L = 1.5 m 
Let the mass of the rod is m and d is the distance between the pivot point and the centre of mass. 
time period, T = 3  s 
the formula for the time period of the pendulum is given by 
 .... (1)
    .... (1)
where, I is the moment of inertia of the rod about the pivot point and g is the acceleration due to gravity. 
Moment of inertia of the rod about the centre of mass, Ic = mL²/12
By using the parallel axis theorem, the moment of inertia of the rod about the pivot is 
I = Ic + md²

Substituting the values in equation (1)


12d² -26.84 d + 2.25 =  0 


d = 2.15 m , 0.087 m 
d cannot be more than L/2, so the value of d is 0.087 m. 
Thus, the distance between the pivot and the centre of mass of the rod is 0.087 m. 
 
        
             
        
        
        
It would still be eastward because The direction of the velocity vector is always in the same direction as the direction which the object moves.
