Answer:
392000
Step-by-step explanation:
8*10^4 = 80000
4*10^6= 4000000
4000000 - 80000 = 392000
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:
The answer is 12, I would know because I just took it
Step-by-step explanation:
Answer:
1) Not a function 2) function 3) function
Step-by-step explanation:
Use the vertical line test. If you draw a line on every vertical line on the graph and you see two points, it is not a function.
