Answer:

Explanation:
The moment of inertia of the system is equal to the each population and the platform inertia so
Inertia disk

Inertia person

Inertia dog

The Inertia of the system is the sum of each mass taking into account that all exert the force of inertia:



 
        
             
        
        
        
I believe the last time the dead bird count was updated (12/16/16), there is a count of 1,350 dead birds. There is 1,350 dead birds from 33 countries have tested positive for WNV in 2016.
        
             
        
        
        
Answer:
 
Explanation: Weight of space probes on earth is given by:
W= weight of the object( in N)
m= mass of the object (in kg)
g=acceleration due to gravity(9.81  )
)
Therefore,


Similarly,


Now, considering these two parts as uniform spherical objects 
Also, according to Superposition principle, gravitational net force experienced by an object is sum of all individual forces on the object.
Force between these two objects is given by:

G= gravitational constant ( )
) 
 = masses of the object
= masses of the object
R= distance between their centres (in m)(18 m)
Substituiting all these values into the above formula
 
This is the magnitude of force experienced by each part in the direction towards the other part, i.e the gravitational force is attractive in nature.
