Answer:
88 m/s
Explanation:
To solve the problem, we can use the following SUVAT equation:

where
v is the final velocity
u is the initial velocity
a is the acceleration
d is the distance covered
For the car in this problem, we have
d = 484 m is the stopping distance
v = 0 is the final velocity
 is the acceleration
 is the acceleration
Solving for u, we find the initial velocity:

 
        
             
        
        
        
Answer:
.10/KWh
Explanation:
divide 606 by 61.37 and you get .1012...
 
        
             
        
        
        
You just multiply these two numbers, it's 1250J
        
             
        
        
        
I think the correct answers from the choices listed above are options 1, 5 and 7. Angular momentum quantum number determine the energy of an orbital, the shape of the orbital and <span>the overall size of an orbital. Hope this answers the question.</span>
        
                    
             
        
        
        
The volume of a warmed part of the air is reduced and its density increases.
Explanation:
In a convective form of heat transfer, the volume of a warmed part of air is not reduced and its density does not increase. 
During convection, heat causes the warm part of the air to expand and its volume increases. When volume increases, density is reduced. 
- Convection is a form of heat transfer that involves the actual movement of particles of the medium. 
- It usually occurs in fluids i.e gases and liquids. 
- In convection, the cold part exerts a buoyant force on the warmer air below and causes it to rise. 
- As the warmer part is rising the cooler part replaces it and a convective cell is formed in the process.
