Where are the lines?
Step-by-step explanation:
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)
Answer:
independent: b
dependent: p
Step-by-step explanation:
p = 2b
To find p, choose values for b, then do the calculation.
b is independent. You can choose any value for it.
p is dependent since its value depends on the value you chose for b.
Answer:
see explanation
Step-by-step explanation:
These are the terms of an arithmetic sequence with n th term
= a + (n - 1)d
where a is the first term and d the common difference
d = 25 - 20 = 30 - 25 = 5 and a = 20, hence
= 20 + 5(n - 1) = 20 + 5n - 5 = 5n + 15 ← n th term formula
