Explanation:
0.004 of something added to 0.12508 of the same thing
adds up to 0.12908 of it.
The thing could be a glass of water, a sheet of paper,
a pound of ground beef, a gallon of gas, or a snowball.
In this problem, it just happens to be a dm.
To calculate the momentum, you have to use the equation p=mv or p to mass times velocity.
Answer:
<h3>
The area of second coil is ≅ 0.025 
</h3>
Explanation:
Given :
No. of turns in the first coil 
No. of turns in the second coil 
Area of first coil 
According to the law of electromagnetic induction,
Induced emf = 
Where 
magnetic flux.
Since given in question emf of both coil is same so we compare above equation.
Therefore, the area of second coil is ≅ 0.025
