Answer:
The density of the copper is higher than aluminium. Hence it is heavier compared to aluminium conductors it requires strong structures and hardware to bear the weight. More ductile and has high tensile strength.
...
Aluminium & Copper properties.
Property Copper (Cu) Aluminium (Al)
Density (g/cm3) 8.96 2.70
Answer:
The strength coefficient is 
and the strain-hardening exponent is 
Explanation:
Given the true strain is 0.12 at 250 MPa stress.
Also, at 350 MPa the strain is 0.26.
We need to find 
and the 
.
We will plug the values in the formula.
We will solve these equation.
plug this value in 
Taking a natural log both sides we get.
Now, we will find value of 
So, the strength coefficient is and the strain-hardening exponent is .
Answer:
Digestion
1 is correct since you need to eat something before anything else.
2 is incorrect since if this was first, what are you storing?
3 is incorrect since that is the second thing you need to do.
4 is incorrect since that is the last thing to do.
