Answer
The nail will become an electromagnet.
Explanation
When the switched is closed , a current will flow in the insulated wire. Then the current flows through the coil around the iron nail, it will induce am magnetic filed inside the nail. The nail becomes a magnet because it is made of magnetic material. As long as there is current flowing through the current, there nail will remain a magnet.
Answer:
The correct answer is "6.96 rad/s".
Explanation:
The given values are:
Length,
L = 0.6 m
Mass,
m₁ = 0.5 kg
m₂ = 0.2 kg
Initial velocity,
V = 8 m/s
Now,
The final angular velocity will be:
⇒ 
By substituting the values, we get
⇒ 
⇒ 
⇒ 
If valence electron i.e electron from 3s orbital is removes, sodium will have configuration same as Neon with a +1 charge on it.
Hence charge on the ion will be +1.
