<u>Answer:</u>
2N/cm
<u>Step-by-step explanation:</u>
According to the Hooke's Law, the force required to extend or compress a spring is directly proportional distance you can stretch it, which is represented as:
where, 
is the force which is stretching or compressing the spring,
is the spring constant; and
is the distance the spring is stretched.
Substituting the given values to find the elastic constant to get:
Therefore, the elastic constant is 2 Newton/cm.

The third stage of parturition is called " after-birth".
Explanation:
Answer:
3.46 A
Explanation:
The force (F) exerted on a wire of a particular length (L) carrying current (I) through a magnetic field (B) at an angle (θ) to the magnetic field is given as
F = (B)(I)(L) sin θ
F = 3.13 N
B = 0.360 T
I = ?
L = 2.50 m
θ = 79°
3.13 = (0.360 × I × 2.5 × sin 79°)
0.8835 I = 3.13
I = 3.54 A
But this is the resultant current in this magnetic field.
Since the two wires are conducting current in opposite directions,
Resultant current = 7 - (current in the other wire)
Current in the other wire = 7 - 3.54 = 3.46 A
