PLEASE HELP will thumbs up

ONLY G,H,I

Tensile Test on a material specimen and the following stress-strain data points were collected: a) The 0.2% Offset Yield Strength/Stress= 377mPA b) The Ultimate Strength =524mPA c) The Approximate Modulus of Elasticity =1850mPA d) The Percent Elongation at Fracture =(L/L)100=17100=1700% e) The metric stress value of 350MPa is equivalent to a US Customary Stress of 50763.2 pounds per square inch (psi). f) What kind of behavior is demonstrated in the Stress-Strain diagram - is it ductile behavior, or is it or brittle behavior (and why)? Which one? It is considered to be ductile behaviour due to the fact that it exceeds 5% elongation. g) Please mark (draw) on the graph what the result would be if the material was stressed to 450MPa and returned to 0MPa (show the return "curve"). h) What would the value of the slope of the return "curve' be = approx. i) If the material was stressed as in question 1g, what would the new yield strength be approx. =
