The last FRQ on the non-form O was so difficult

@glasshours no idea!

also the mc question with the super weird graph – I was like huh???

NOW I’M DOUBLE-GUESSING MYSELF
What was so difficult about the last FRQ on form O? Wasn’t it just about waves and different frequencies?

@glasshours it wasn’t hard at all, I’m just checking my answer

How did you guys design the experiment?

NONLINEAR…right???

no not the last mc questuion, the last frq question

@notreadyforlife yeah

for the last frq question i made a mark every two points until the end but i was just guessing so lol

The first part was series, the second parallel, I think
I was so happy when I saw that question. We did that EXACT lab in school a week ago :slight_smile:

i put nonlinear idk

What did you say the frequency was dependent on? Linear density right?

@outlooker simple, just an ammeter next to the power source, a voltmeter parallel to the light bulb, and also an ammeter right after the light bulb. At least thats what I did

Too late

Isn’t f^2 proportional to the inverse of m/L?

@tommyeventing That’s what I put down.

@glasshours what do you mean by the first part series?

Nonlinear huh well i got a 3 at the most then smhhh

the second harmony one is what i mean, no clue how to do that
