Answer:
The magnetic flux links to its turns = 
Wb.
Explanation:
Given :
Radius of circular coil = 
m
Number of turns = 25
Magnetic field = 
T
Magnetic flux (Φ) is a measure of the magnetic field lines passes through a given area. The unit of magnetic flux is weber (Wb).
We know that,
⇒ Φ = 
Where 
ext. magnetic field, 
area of loop or coil.
But here given in question, we have turns of wire so our above eq. modified as follows.
⇒ Φ = 
Where 
no. of turns.
∴ Φ = 
Φ = 
Thus, the magnetic flux links to its turns =
The total kinetic energy of the system after collision is 223.5J
In elastic collision kinetic energy and momentum are conserved.
According to the question
mass of object a = 25kg
mass of object b = 25 kg
initial velocity of a u1 = 5.98 m/s
initial velocity of b u2 = 0
so from momentum conservation-
mau1 + mbu2 = (m1+m2)v
25kg × 5.98m/s + 25×0 = (25+25)v
v = 2.99 m/s
Now the total kinetic energy after the collision will be:
final kinetic energy = 1/2 (m1+m2) v²
= 1/2 (25+25)× (2.99)²
= 223.5 J
Thus, total kinetic energy of the system after collision is 223.5J
