The amount of force required to stretch or compress the spring is known as the spring force. Its unit is Newton(N). Force is needed to stretch spring is 10.2 N.
<h3>What is spring force?</h3>The force required to extend or compress a spring by some distance scales linearly with respect to that distance is known as the spring force. Its formula is
F = kx
The given data in the problem is;
F is the spring force =?
K is the spring constant= 8.5 N/m
x is the length by which spring got stretched = 1.2m
Hence the force is needed to stretch the spring is 10.2 N.

Answer:
Δh_air=714m
Explanation:
Given data
Solution
ΔP=P₁-P₂
=(ΔhHg)×pHg×g
=(Δh_air)× p_air ×g
Then
Δh_air=(pHg+ΔhHg)÷p_air
Δh_air=714m
