Answer: 7.436 s
Explanation:
This situation is related to vertical motion, specifically free fall and can be modelled by the following equation:
 
   
Where:
 is the final height of the object (when it makes splash)
 is the final height of the object (when it makes splash)
 is the initial height of the object
  is the initial height of the object
 is the initial velocity of the object (it was dropped)
  is the initial velocity of the object (it was dropped)
 is the acceleration due gravity (directed downwards)
  is the acceleration due gravity (directed downwards)
 is the time since the objecct is dropped until it makes splash
 is the time since the objecct is dropped until it makes splash

Answer;
= 3.86 × 10^8 Meters
Explanation;
-The distance between the Earth and the moon is 386000 km
But; 1 km = 1000 m
Therefore; 386000 km will be equivalent to;
= 386000 × 1000
= 386000000 m
= 3.86 × 10^8 meters
 
        
                    
             
        
        
        
A freight car of mass 20,000 kg moves along a frictionless level railroad track ... After the push the skateboarder II moves with a velocity of 2 m/s to ... After the collision the cars stick to each other and ... diver jumps with a velocity of 3 m/s in opposite ... A 10 kg object moves at a constant velocity 2 m/s to the right and collides
 
        
             
        
        
        
Answer:
Well the definition of an application is the act of putting to a special use or purpose so lam assuming that you want specific uses that scientists make of gravity in their work.
Well our first application has helped us to send satellites around the solar system with what Nasa calls gravity assist. Using a particular planets gravity to slingshot a satellite to another destination. Look it up.
The next application much simpler but here on Earth. There are many hydro-electric power stations in use all over the world. Water is stored at a high level and released falling 100s of metres to a turbine where it generates electricity.
Hope that helps.
