The second line
Step-by-step explanation:
18 friends
Explanation:
I saw many questions like this. Just use division:
6 ÷ 1/3 = 18
Trust me, this is easy math
A brainliest would be nice, just talk to me back if my answer is correct!

Answer:
k = Y*A/L
Step-by-step explanation:
We can apply the Law of Hooke in order to explain the problem.
If we define k = F / ΔL and the Y = S / δ
Where S is the uniaxial stress: S = F / A <em>(i)</em>
and δ is the strain: δ = ΔL / L <em>(ii) </em>
ΔL is the change in length
we can combine the equations i and ii as follows
Y = (F / A) / (ΔL / L) = (F * L) / (A * ΔL) <em>(iii)</em>
if k = F / ΔL the equation <em>iii</em> results
Y = k * (L / A) ⇒ k = Y*(A / L)
It’s A you just multiply the keys
