like a straight line down not a curve?
and for the precision ones i got 25.5 ± 0.something
acceleration would be 0 for the first interval and negative line for the second interval
@Jaybee2016 yeah that’s what i got too
Hey @AverageStudent97 when you said “negative line” did you mean a negative horizontal line right?
@newCCuser12345 yeah negative horizontal line
For the ruler one it should be 25± 0.1.
For measuring you estimate one decimal place more than what you get. The increments were by 1 so you could see that the ruler passed 25 cm. You’re at the ones place so you “guess” the next decimal place which is the tenths place.
@rdeng2614 from what i know you take one more decimal place than what the mark shows. The only reasonable answer choice was 25.5±0.2 I thought?
25.0±0.2*
@averagestudent Was there an option for BOTH 25.0+=0.1 and 25.0±0.1?
there was 25.0±0.2 but i don’t think there was 25.0±0.1
I thought the ruler was 25.5+0.2 because you know it is 25 for sure, and then the 0.5 is the uncertainty.
What about the one that was how to measure 1.756 meters?
Also, what are your curve predictions?
Was the question to “What holds the charge of a camera flash before it goes off” battery or capacitor?
Capacitor
I think I got 6-8 wrong, so I’m pretty bummed out. Also, I put only one of them could accurately measure the 1.756 meters
@Literallydone Which one? The 50 m one with 0.02 mm intervals or the 2 m one with 0.01 mm?
I am 99% positive the increments were by 0.5 cm. And also the place where the object was at greater than 25.5 cm visually, so even if you were to say 25.0 cm as a baseline for estimation, you would still have to say something like +/- 0.7 cm after.
I am pretty sure the answer is the one with 25.5 cm.
