Answer:
116
Explanation:
The transformer equation states that:
where
Vp is the voltage in the primary coil
Vs is the voltage in the secondary coil
Np is the number of turns in the primary coil
Ns is the number of turns in the secondary coil
Here we have:
Vp = 5670 V
Np = 2750
Vs = 240 V
So we can solve the formula to find Ns:
So, the secondary coil has 116 turns.

The following are four real life examples of the result of scientific investigation:
1. The development of the whole human genome.
2. The discovery of penicillin.
3. The discovery of a drug that cures tuberculosis.
4.The discovery that atoms have different energy levels and that electrons are found at each level.
All these events comes about as a result of scientific investigations.
The potential difference isV=220−85=135.
Now the potential V at distance d from a point charge Q isV=Q/4πϵ0d
If you solve this for d and plug in the potential difference you will get the answer.
Energy is the ability to do work.
