Answer:
79.74*10^6 Pa
Explanation:
Based on the parameters provided, we have:
ε = ln()
Where initial gauge length = 3 cm and the final gauge length is 3.5 cm. Therefore:
ε = ln(3.5/3) = ln(1.167) = 0.154
Similarly,
σ = F/[3.142*(di^2)/4]
Where σ = 120*10^6 Pa and di = 1 cm = 0.01 m
Therefore,
F = 120*10^6 * 3.142*(0.01^2)/4 = 9426 N
σ = F/[3.142*(df^2)/4 = 9426/[3.142*(0.00926^2)/4 = 9426/6.74*10^-5 = 139.95*10^6 Pa
σ = k*ε = 139.95*10^6
k = 139.95*10^6/(0.154)^0.5 = 356.63*10^6 Pa
Therefore, when ε = 0.05 cm/cm
σ = 356.63*10^6 (0.05)^0.5 = 79.74*10^6 Pa
In complex compounds coordination number is the number of atoms or polyatomic ions surrounding the central metal. In given statement the coordination number given is 6, means there are 6 ligands surrounding the metal atom, and the ligands given are only NH₃, so 6 NH₃ molecules are surrounding the Cobalt atom. Hence,
[Co (NH₃)₆]
As, NH₃ is neutral so the charge on sphere will be the charge on Co, as charge given in statement id +3 so,
[Co (NH₃)₆]³⁺
Name of this complex is as follow,
Hexaamminecobalt (III) Ion
Answer:
A substance that is dissolved in a solution is called a solute
Explanation:
Solute is the substance which is dissolved
Solvent is where you dissolve the solute (usually liquids)
Solution = Solute + solvent
Answer:
No
Explanation:
it will not be a irreversible change because u can give back the pen if it is in its original state and the shop keeper might accept it back that is what mostly happens. if the pen breaks or is used then it might me called a irreversible change until then it is reversible if not used yet.
thank u
<span>A lime is called a lime because it's lime in colour and a lemon is called lemon because it's lemon in colour. Just to change the subject slightly why is a fly called a fly? - because it flies - so if a fly didn't have wings would it be called a walk. We could go on and on with this couldn't we and have a lot of fun too :)</span>
