A step-up transformer with 300 turns in the primary coil is supplied with 220 volts to this primary. How many secondary turns are needed to produce a 66,000 volt output?

Number of tuns in the secondary coil be 99000 volt.

Explanation:

Given that,

Number of turns in the primary coil,

Voltage of the primary coil,

Voltage of the secondary coil,

Let number of tuns in the secondary coil be . It can be calculated using the turn and voltage ratio. It is given by :

So, the number of tuns in the secondary coil be 99000 volt. Hence, this is the required solution.  

if the forces acting on an object are unbalanced, the object will accelerate in the direction of the net force on the object.

explanation:

this is best explained by having an understanding of newton's second law, which states that f=ma. you see, when the forces are unbalanced, net force (sum of all forces) is not zero. therefore making it necessary for the object to have an acceleration in the direction of the net force.
