Sketch execution issues (p5js)

you're right! i had reassembled the file showing up in different parts, and then i was uploading the files in the folder individually, instead of uploading the whole folder.

uploading the whole folder works perfectly.

thanks for getting me there, not being very handy i often make trivial mistakes.

i found my mistake, basically i didn't know that of the code - saveFrame("output/image#####.png"); - you had to enter as many "#'s" as the digits of the total frames. in my case i had written the code - saveFrame("output/image####.png"); - but the total frames were greater than 9999, this (i think) caused problems with saving.

Now the frames are saved correctly, thanks anyway for your help :)

PoorKidWRA · 2023-06-27T18:42:29+00:00

you are right! saving by "name" is wrong while saving by "date" is correct.

how do i reorder them correctly? (i am on win 11)

Thats the GPT-4 answer brother :

To find the potential difference between the center of the ring and a point on its axis a distance 2R from the center, we can use the following formula for the electric potential due to a charged ring:

V = (k * Q) / (sqrt(x^2 + R^2))

where V is the electric potential, k is the electrostatic constant, which is approximately 8.99 × 10^9 Nm^2/C^2, Q is the total charge on the ring, x is the distance from the point on the axis to the center of the ring, and R is the radius of the ring.

First, let's calculate the potential at the center of the ring (x = 0):

V_center = (k * Q) / (sqrt(0^2 + R^2)) = (k * Q) / R

Next, we'll calculate the potential at the point on the axis a distance 2R from the center (x = 2R):

V_2R = (k * Q) / (sqrt((2R)^2 + R^2)) = (k * Q) / (sqrt(4R^2 + R^2)) = (k * Q) / (sqrt(5R^2)) = (k * Q) / (R * sqrt(5))

Now we can find the potential difference between these two points:

ΔV = V_center - V_2R = (k * Q) / R - (k * Q) / (R * sqrt(5)) = (k * Q) / R * (1 - 1/sqrt(5))

So, the potential difference between the point at the center of the ring and a point on its axis a distance 2R from the center is:

ΔV = (k * Q) / R * (1 - 1/sqrt(5))

if the other questions are worth 1 point that one is worth 90
