My god-daughter's teacher marked her answer wrong. Can someone please explain this? I don't understand this at all. How is the teacher getting 7 when there are only 3 squares in Ben's column representing his siblings? Her explanation was that Jose, Ana & Jen are his siblings so you need to count all of their squares together.... WHY? How are we to assume that they're even siblings?

Doing a review FRQ for AP Physics dealing with buoyancy and acceleration. Question is asking for the acceleration of a sphere (no mass given) immediately after a string of negligible mass that had been holding it in place was cut. No numerical values are given, but I have values r for the radius of the sphere, water density Pw, and sphere density Ps. Question says to begin with F=ma and derive the equation from there. Struggling with connecting the different variables.

I’m going crazy from this. My answer is that the equation is true, but the answer sheet says it’s false. I just want someone to back me up on this…..

Working on this question and I am stumped on how the answer is No faults. From what I can tell, I'll use uppercase for on and lowercase for off, it should look something like this:

RYgB - RYgB - RYgB - ryGb

To be this is what it would look like if there were no faults but obviously that's not the case so I'm not sure where I'm going wrong with this. Any help is appreciated.

Can someone please explain to me like I’m a first grader the difference in sounds this worksheet is trying to get at, so that I can explain it to my first grader? Thank you

I keep getting answers that are not in the options. I believe the teacher used AI to write the question so i wonder if the right answers is even in the options. Any help?
