The voltage entering a transformer’s primary winding is 120 volts. The primary winding is wrapped around the iron core 10 times.
loris [4]
<u>Answer</u>

 48 Volts  

<u>Explanation</u>
The question can be solve using the turn rule of a transformer that states;

Np/Ns = Vp/Vs
Where Np ⇒ number of turns in the primary coil.
            Ns ⇒number of turns in the seconndary coil
            Vp ⇒ primary voltage
             Vs ⇒secondary voltage

Np/Ns = Vp/Vs

10/4 = 120/Vp

Vp = (120 × 4)/10

      = 480/10
      = 48 Volts

Answer:

the magnetic field is leaving the sheet

Explanation:

The magnetic force is given by the expression

        F = q v x B

where bold letters indicate vectors, the modulus of this expression is

       F = q v B sin θ

the direction of the force is given by the right hand rule, for a positive charge

the thumb indicates the direction of the speed, in this case from right to left

the palm the direction of the force, in our case upwards

the fingers extended the direction of the magnetic field, this case after fixing the other two components it points out of the blade

In short the magnetic field is leaving the sheet

CRIMINOLOGY
lbvjy [14]

Answer:

<h3>Two-track correctional system is a system of consisting two correctional institutions for criminals.</h3>

Explanation:

  • The two-track correctional system is a correctional system that consists of two separate correctional institutions for criminals. One institution for juveniles and one for adult criminals.
  • No, two-track correctional system would not work better in our country. There are many cases of serious juvenile crimes in our country. Juveniles who commit serious or atrocious crimes should be dealt strictly in an adult or criminal court without exemption.
  • Yes, this would reduce the percentage of offenders re-entering the system because juveniles incarcerated for serious crimes would be locked up in the prison instead of being acquitted after a short detention.
  • This would stop them from committing similar offences and would reduce potential crimes from ex-convicted juveniles.
