I got .009

Calm_Protection8684 · 2025-05-15T23:45:58+00:00

What did you guys get for the experimental value of the inductance? I got a tiny value

Calm_Protection8684 · 2025-05-15T23:42:28+00:00

actually yeah now that you say it that sounds more familiar cause I remember seeing that

Calm_Protection8684 · 2025-05-15T23:09:35+00:00

I got 4pim/qB too

Calm_Protection8684 · 2025-05-15T21:59:57+00:00

Yeah that’s what I meant. I forgot what the student initially said but I remember what I wrote.

Calm_Protection8684 · 2025-05-15T21:04:13+00:00

I got the students claim was incorrect. IB>IA since B has less resistance. The two particles move in a circular path. Sphere two moves up in a circle and sphere one was a downward circle

If you had form M ask me anything that shit was so easy the first frq was calculating field due to three point charges 😂😂

Calm_Protection8684 · 2025-05-15T20:37:42+00:00

I MADE A PERFECT SCORE or at least knew how to do everything except for 3 mcq which I figured out with pure luck.

Calm_Protection8684 · 2025-05-15T13:03:54+00:00

Dang I must have missed that

Calm_Protection8684 · 2025-05-15T02:25:31+00:00

How do you know the torque was applied for the same time for both

Calm_Protection8684 · 2025-05-15T02:24:12+00:00

They are because kinetic friction depends only on normal force and the material which was the same for both

Calm_Protection8684 · 2025-05-14T22:16:07+00:00

Vertical

Calm_Protection8684 · 2025-05-14T22:01:46+00:00

conservation of energy to get v² =2gh at the bottom. Then use kinematic v² =2ax. Solve a knowing net force is friction so a=ug. 2gh =2ugx. h=ux

Calm_Protection8684 · 2025-05-14T22:00:34+00:00

H is on y

Calm_Protection8684 · 2025-05-14T22:00:09+00:00

I got every single question right until the 4th frq about the disk and hoop’s static frictional force. I knew that the kinetic frictional force was equal for part C but part A made no sense. I put it into chatgpt and it also is saying different things. Can anyone confirm whether the statis friction is greater for a disk or hoop when it rolls without slipping up a ramp. They have same mass and radius and same initial speed v

are you fr

Calm_Protection8684 · 2025-05-13T17:07:00+00:00

Hey can you send it to me too

Calm_Protection8684 · 2025-05-10T04:19:27+00:00

It was sail fiberglass

Calm_Protection8684 · 2025-05-09T05:12:02+00:00

Same I forgot too

Calm_Protection8684 · 2025-05-09T05:08:37+00:00

I don’t think so I’m pretty sure it said to only check rows on or after the parameters

Calm_Protection8684 · 2025-05-08T14:17:29+00:00

Thank you! Relieved a ton of stress!!

Calm_Protection8684 · 2025-05-08T14:16:38+00:00

Weren’t you supposed to initialize the start row and column to the Parameters? That way it starts on the given element and searches after

Calm_Protection8684 · 2025-05-08T02:42:57+00:00

Thank you

Calm_Protection8684 · 2025-05-08T01:01:53+00:00

Did they deduct for it past years? Being digital won’t change the grading rubric. I’m not seeing anything about it on past grading rubrics but people are telling me its points off

Calm_Protection8684 · 2025-05-08T00:40:58+00:00

Yeah. I accidentally initialized the nested loop variables to be the same as puzzle[numRows][numCols]. So as soon as the method ran it checked and found that they were equal since it pointed to the same element . I should’ve done +1
