well... the exam was sorta medium difficulty :V That spider and fly question was damn tricky though xD what was your value for acceleration in that question ?

copper is malleable so it can be shaped into sheets. petal is a sheet so copper is suitable steel is ductile so it can be shaped into rods or wires. stem is a rod so steel is suitable

I wrote the same yes but idrees and waleed said copper can't be malleable
And what abt yeild point why it's defination was incorrect I wrote because instead of extension it should be strain as graph is for stress and strain or force instead of stress
What did you choose in that mcq where a car goes towards east then west ? i chose change in speed = 20 change is velocity= 20-(-40)=60 coz 40 was in neg direction

Final -initial So -40-20 -60 was change in velocity

i mentioned that student shouldve used the word strain instead of ext coz yield point = more increase in strain for small increase in stress
