Answer:

N_s :  N_p = 20 : 1

Explanation:

From the question we are told that

    The primary voltage is  V_p  =  120 \  V

     The secondary voltage is  V_s  =  6 \  V    

     

Generally from the transformer equation we have that

        \frac{V_p}{V_s}  =  \frac{N_p}{N_s}

So

       \frac{120}{6}  =  \frac{N_p}{N_s}

=>      \frac{N_p}{N_s} = 20

Therefore the ratio of the number of turns in the secondary to the number of turns in the primary is  

       N_s :  N_p = 20 : 1

Example of an unbalenced force
lesya692 [45]

Answer:

Explanation:

unbalance force can be defined as the force that makes object slow up or down, in order words unbalanced force can be  defined as anything that can alter the state of motion of an object.

an example of an unbalanced force is likened to a situation of someone inside a lift going for a meeting at the top floor, the force which propels the lift upward is unbalanced, because it is greater than the force acting on the lift.
