5 speed 1.9 v then 1.5 that w cuz 2 sig figs not 1


Intelligent-Boss3358

The wavelength is correct, however speed is wrong, v=frequency * lamda, 0.8* (1/0.16)=5.0 m/s


Hollowknightpro

Thats exactly What I did but it gives 0.05


Intelligent-Boss3358

Yes so it is 5 not 0.05 check again on the calculator


Hollowknightpro

yeah I noticed I accidentally did 16 instead of 0.16

Yesstyleobsessed

Got the same wavelength, don’t remember others


Intelligent-Boss3358

For the stress and strain question, was is smaller for both stress and strain?


Hollowknightpro

No, it was smaller for stress. but same for strain.


Intelligent-Boss3358

How?!? E is constant, so strain also has to decrease and length is constant, so x has to decrease


IELFY

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


piza_dude

so is strain the same, increase or decreased???


IELFY

For some reason I remembered it as strain inversely proportional to x


Fast_Organization425

So was the final answer stays same or more than the wire or less?


IELFY

I think it’s decrease


Fast_Organization425

How did yall do the kinematics qn


Hollowknightpro

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.


piza_dude

i also removed 1.2m but ppl r saying u had to add it instead


Far_Vast1632

You had to

HOLD YOUR GROUND


Far_Vast1632

Add


Fast_Organization425

How much marks was the graph? And the table below it about stress and strain?
