The speed of tsunami is a.0.32 km. 
Steps involved  : 
The equation s = 356d models the maximum speed that a tsunami can move at. It reads as follows: s = 200 km/h d =? 
Let's now change s to s in the equation to determine d: s = 356√d 200 = 356√d √d = 200 ÷ 356 √d = 0.562 Let's square the equation now by squaring both sides: (√d)² = (0.562) ² d = (0.562)² = 0.316 ≈ 0.32 
As a result, 0.32 km is roughly the depth (d) of water for a tsunami moving at 200 km/h.

Heat!!!!!!!!!!!!!!!!!!! sorry about the exclamation marks but it wont let me post in less it has more than 20 characteristics
        
             
        
        
        
Option number three is correct energy can be transformed and moved and released but it can't be destroyed and doesn't disappear.
        
             
        
        
        
The formula of the kinetic energy is:

where m is a mass of the object, v is speed of the object at the moment of time. So we have:

The answer is 
2000 Joules.
 
        
        
        
Energy is released in the reaction
Explanation:
In a given where the energy of the products is greater than that of the reactants, we can infer that energy is released in the reaction. 
This indicates that the reaction is an exothermic or exergonic reaction. 
These reaction types are accompanied by release of energy. 
- In an exothermic change energy is released to the surroundings. 
- The surrounding becomes hotter at the end of the change. 
- This applies in exergonic reaction which leaves a reaction having more energy than it originally started with.
