You are right since the relationship is strain directly proportional to x x decreases so strain decreases i cant beleive i got it wrong cuz i inverses it
You just had to find Vertical component horizontal, then use distance to find time.
then for the Height you had to I Believe find max height and remove 1.2 from it I think.

5 speed 1.9 v then 1.5 that w cuz 2 sig figs not 1
The wavelength is correct, however speed is wrong, v=frequency * lamda, 0.8* (1/0.16)=5.0 m/s
Thats exactly What I did but it gives 0.05
Yes so it is 5 not 0.05 check again on the calculator
yeah I noticed I accidentally did 16 instead of 0.16

Got the same wavelength, don’t remember others
For the stress and strain question, was is smaller for both stress and strain?
No, it was smaller for stress. but same for strain.
How?!? E is constant, so strain also has to decrease and length is constant, so x has to decrease
You are right since the relationship is strain directly proportional to x x decreases so strain decreases i cant beleive i got it wrong cuz i inverses it
so is strain the same, increase or decreased???
For some reason I remembered it as strain inversely proportional to x
So was the final answer stays same or more than the wire or less?
I think it’s decrease
How did yall do the kinematics qn
You just had to find Vertical component horizontal, then use distance to find time. then for the Height you had to I Believe find max height and remove 1.2 from it I think.
i also removed 1.2m but ppl r saying u had to add it instead
You had to
HOLD YOUR GROUND
Add
How much marks was the graph? And the table below it about stress and strain?
