Answer: 
Option (C)
Explanation:
Flash flood refers to the sudden flood that occurs in a particular area due to the heavy and excessive amount of rainfall, often accompanied by thunderstorms within a few hours. It releases a huge amount of water due to the failure of natural levee as well dam. They are very devastating. During flash flood, the water exerts a massive force which can make vehicles float over water. The <u>six inches of water</u> that flows over an area has the capacity to lift the tyres of small vehicles and carry hem further away.
Thus, the correct answer is option (C).
 
        
             
        
        
        
Answer:
The value  
Explanation:
From the question we are told that 
    The volume blood  ejected is  
     The velocity of the blood ejected is  
     The density of blood is  
      The heart beat is 
The average force exerted by the blood on the wall of the aorta is mathematically represented as 
       
=>    
=>    
 
        
             
        
        
        
Answer:
The outer core is a liquid
Explanation:
The outer core is a fluid composed of iron and nickel
 
        
                    
             
        
        
        
Explanation:
A concave meniscus,(normally seen) occurs when the molecules of the liquid are attracted to those of the container. This occurs with water and a glass tube. A convex meniscus occurs when the molecules have a stronger attraction to each other than to the container, as with mercury and glass.
 
        
                    
             
        
        
        
Answer:
The velocity of the cart at the bottom of the ramp is 1.81m/s, and the acceleration would be 3.30m/s^2.
Explanation:
Assuming the initial velocity to be zero, we can obtain the velocity at the bottom of the ramp using the kinematics equations:

Dividing the second equation by the first one, we obtain:

And, since  , then:
, then:

It means that the velocity at the bottom of the ramp is 1.81m/s.
We could use this data, plus any of the two initial equations, to determine the acceleration:

So the acceleration is 3.30m/s^2.
