You need to consider the following:
Me (mass of Earth) = 5.98 x 10^24 kg 
<span>Ms (mass of Sun) = 1.99 x 10^30 kg </span>
<span>G = 6.67 x 10^-11 N </span>
<span>
Formula:
 F = G * M1M2/r^2 
</span><span>The ratio FT/F = 4.02x10^-4 / 14.8
 = 2.72x10^-5 
</span><span>
Since,
1/2.72x10^-5 = 36800
The fraction ratio is  1/36800
</span>= <span>9.56x10^17 N</span>
        
                    
             
        
        
        
Transformer contains two coils: primary and secondary. They allow change of voltage to lower or higher value. In first case we have step-down and in second case we have step-up transformer.
Formula used for transformer is:

Where:N1 = number of turns on primary coilN2 = number of turns on secondary coilV1 = voltage on primary coilV2 = voltage on secondary coil
In a step-down transformer primary coil has more turns than secondary coil. So the ratio 1:38 means that for each turn on secondary coil we have 38 turns on primary coil.
We can solve the equation for V2:

Secondary coil provides voltage of 3.16V.
 
        
        
        
Answer: When the car speed triples, momentum also triples but Kinetic energy increases 9 times or by 9 fold.
Explanation:
The momentum of a car (an object) is 
p= mv
where
m is =the mass of the object( in this case car)
v is its= velocity
While the kinetic energy is is given by the formulae
K=1/2mv²
To determine how momentum and kinetic energy of the  car changes when the speed of the object triples, We have that the new velocity,
v¹= 3v
So that  the momentum  change becomes
p¹=mv¹=m (3v)= 3mv
mv=p
therefore p¹= 3p
 we can see that the momentum also triples.
 
And the kinetic energy change  becomes
K¹=1/2m(v¹)²= 1/2m (3v)²
= 1/2m9v²= 1/2 x m x 9 x v²=9 x1/2mv² 
1/2mv²=K
K¹= Kinetic energy = 9k
 but Kinetic energy increases 9 times
