The equation that relates the voltages and the number of turns in a transformer is
where
is the voltage in the secondary coil,
is the voltage in the primary coil, and
and
are the number of turns on the secondary and primary coils.
Using the numbers, we find the ratio between the number of turns:
Answer: Magnitude of electric field =p × Ke × Q/d^3
Explanation: Using Coulombs law of point charge,each charge on the circle would exert a fieldEc at point given by:
Ec= Ke × (Q/n)/d^2
Where Ke= Coulomb's constant
d= distance between the charges and the point of measurement, P with d^2=a^2+p^2
(Q/n)= Magnitude of the charge.
For charges in a circle,all the force components and direction(x,z) are cancelled by the symmetry,leaving only the vertical force(y-direction)
The Resultant vector will be
Ecy=Eq × sin(theta)
Ecy=Ke × (Q/n)/d^2 ×(p/d)
Adding the forces from all the charges,the magnitude of electric field Ey=n×Ecy
/Ey/= n ×[Ke ×(Q/n)/d^2 ×(p/d)]
/Ey/= p × Ke × (Q/d^3)

Answer:
The period of the harmonic vibration is inversely proportional to its frequency
Explanation:
The period of the simple harmonic vibration is actually the inverse of its frequency.
This means that, to get the period, all you have to do is divide "1" by the frequency, in other words:
period = 1/frequency
From this formula, we can note that as the frequency increases, the period decreases and vice versa.
Based on this, the relation between the period and the frequency is an inversely proportional relation.
Hope this helps :)
A basic circuit must contain an energy source or battery, switch, a path, and a resistor.
That's what I remember when I learned that in middle school.
