It depends on the circuit. Sometimes it becomes a bit weaker, sometimes it stays the same.
 
        
                    
             
        
        
        
Answer:
100/10 = 10 , 10 × 10 = 100÷20 = 5 
I'm pretty sure its wrong
 
        
                    
             
        
        
        
The correct answer to the question is : 1) Converting energy and 2) Within about twenty years, natural gas forms.
EXPLANATION:
In coal fired power plants, the water is heated by burning coals. The heat produced in this process will convert water into steam. The steam is allowed to rotate the turbine. The turbine is attached to a generator which converts the kinetic energy of the steam into electric energy due to electromagnetic induction.
Hence, turbine helps in converting energy.
As per the second question, Walt listed the steps that occur during the formation of natural gas.
The natural gas is produced due to natural phenomenon. For this, millions of years are passed. So, it is a long range process in which the fossil of animals and planets buried beneath the surface are converted into natural gas under high pressure.
Hence, the mistake of Walt is  that the natural gas is produced withing twenty years.
 
        
                    
             
        
        
        
Answer:
Time = 80.91 seconds
Explanation:
Given the following data;
Velocity = 5.50 m/s. 
Distance = 445 meters
To find the time;
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction. 
Mathematically, velocity is given by the equation;

Substituting into the formula, we have;
5.5 = 445/time
Time = 445/5.5
Time = 80.91 seconds
