Did it ask for the terminal potential difference at the motor or at the battery? I fucked up the screen brightness thingy😭😭 so I need this one to be right, I got 7.8 at the motor

Does speed increase or stay constant when volume increases? I wrote tht it increases, because volume is 4/3*pi*r^3, so the volume increases at a greater rate than the radius, so speed has to increase.
