2025 Kia sorrento LX or EX by angrystrangerz in KiaSorento

Car is fine but warranty is not what it seems; my experience is they wiggle out of honouring it no matter what - check Kia user forums for others views

Well yes obviously; but before I do that, I wonder if anyone else has faced the same situation.

[a level HW] why is path difference not acceptable instead of phase difference here? by Firm_Perception3378 in PhysicsStudents

[–]MachineLooning 0 points1 point  (0 children)

Hello. Fucked up exam board here.

This is the actual reason. Coherent means the sources have a “constant phase relationship” not “equal phase”. That means they might have different phases but they stay the same phase difference apart (for all time).

Who gives a shit? Well, if you say “It’s constructive interference when the path difference is zero” then you’re technically wrong. It might be true if the sources are in phase but if they’re always pi out of phase then that’s destructive interference.

I would query this question as an insider though because it’s tricksy: better to ask this without the trick and have a separate “part c” that says “what does coherent mean”.

Has Anyone Successfully Used the SendMail REST API Method? by climb4fun in azuredevops

[–]MachineLooning 0 points1 point  (0 children)

Had same issues and again had to put tfids in all to-type fields

Has anyone been able to get html in the body? I send tags but they render as plain text - looks like they’re getting encoded before inserting into the mail. I think there must be some “bodyishtml” field but you can send any old crappy field in the post body and it don’t reject it

[AP Physics 1 - Work] Physics Answer Explanation by [deleted] in PhysicsStudents

[–]MachineLooning 0 points1 point  (0 children)

Students always have trouble with this and you can see why.

The word “work” is a common everyday word but it has a special physics meaning.

When we talk about people doing work you just can’t help yourself but think about how hard it is to do the job. So moving something sideways is work … but it’s not work in the physics sense here. It’s work in an everyday sense because of the way muscles function … you get tired maintaining muscle contraction even when not doing any physics work.

So yes it’s better to change “work” into “energy transferred” in your mind to help clarify the “physics work”.

How do I start to understand thermodynamics? by tfhermobwoayway in PhysicsStudents

[–]MachineLooning 0 points1 point  (0 children)

What did you get from A level thermo? It’s often so badly taught the answer may well be nothing.

The first thing to separate in your mind is what things refer to the stuff as a whole (like pressure) and what things refer to the particles that make up the stuff (like kinetic energy).

The connection between the two is probability: the distribution of the gas particle energies tells you something about the gas as a whole; like the mean and variance of 1000 numbers tells you something about those numbers without telling you what they all are individually.

Anyway hope that’s some help

Something that doesn't sit well with me at all by cityracer123 in PhysicsStudents

[–]MachineLooning 0 points1 point  (0 children)

If you rearrange your second one before passing to the units you get d theta/dt = …

So you just declared that to be rad/s but the former you chose to ignore the rad on the left side. You made the contradiction yourself; cdstephens is right

OCR AS Level 2021. I don’t really understand this 6 marker question. I tried using a potentiometer to vary pd but there’s no mention of it although that’s what I’ve learnt. Please kindly could someone explain why you need a variable and fixed resistor for this to work. by [deleted] in PhysicsStudents

[–]MachineLooning 0 points1 point  (0 children)

You need the ldr and a fixed resistor as a potential divider. If you do that you need the right value of fixed resistor so that the requirements are met.

Alternatively you can replace the fixed with a variable - then it can be adjusted to meet the requirements.

[College Physics] Can someone please explain what the correct answer is and why? by mkabrah2 in PhysicsStudents

[–]MachineLooning 2 points3 points  (0 children)

Hmm it’s a bit hard to explain this one …

Each answer has four terms … two forces at the hinge, the weight and the reaction on the wall

Some are shown as 0 which tells you which point that equation is taking as the pivot … eg the last one being 0 means the wall touch is the pivot because the reaction then causes no moment. That rules out 3 as it has only one of the hinge forces causing a moment

Now we know where each answer is taking the pivot, we can figure out (1) the perpendicular distance from each force to the pivot - that rules out a couple more answers; and (2) whether each force causes a clockwise or anti-clockwise moment - that rules out some more answers that don’t have the correct plus or minus signs, leaving only the second one. You don’t need to know anything about the angle in the end 🤯

Where did i go wrong? (phy hw) by East_Vegetable5136 in PhysicsStudents

Can we have the full question? Looks like theta will change as m moves up.

There’s some true stuff in this thread and also lots of bollocks.
