i know it sounds stupid, but i can't seem to find an answer to it
where did the energy went? you can't just just destroy energy, but when you red shift a gamma CMB into a microwave CMB, the energy has go to go somewhere...?
it's not like one gamma photo spitted into many microwave, cause that...
It's just that I've never properly sorted this confusion of mind, so i would like to sort it out
so it 2 different capacitors are in series with a resistor: (let's say 0.15F, 0.45F, 150M ohm)
1. both current and voltage drops exponentially
2. capacitance on capacitors remain same over time?
2...
This is the question and the answer, the problem is i don't know how to get to the answer
top is question and bottom is answer
I attempted to divide the gas concentration by 24 to get molar mass, but that didn't work
and how am i suppose to know that OH- is one of the products? i guessed...
Hi, i'm looking for an explanation to this answer of a past paper that I'm doing, it's from OCR (A level) G485, question 1 b ii)
the question on top, and answer on bottom
i don't understand why would the point experience a negative electric field strength when it's getting closer to a...
the black triangle is given, and red triangle is me trying to work it out
why is my trangle wrong? and what is the right triangle?
someone is sliding down a slope, with 2ms-2 of acceleration (not actually given which direction, maybe I'm wrong there, but the person is acelerating at 2ms-2 down...
i'm ashamed, that i never understand this, eventhough I'm studying quantum mechanics...
so... why is there "weightlessness" on the top of a verticle circular motion?
ie, if a plane if flying in verticle circles, why is there weightlessness while on the top of a circular path?
i mean, if it's...
I've recently read a new article that said that the recent gravitational waves might have had 2 black holes in a star
that gave me a question, because you need masses to move or accelerate to generate gravitational waves, what happens to the mass inside of the star? because black holes's space...
thankyou, i think I've had enough info to go back into research now,
because, my main problem is that internet doesn't always give you the right answers, that's why i do sometimes asks some weird questions before i go into deeper research, and I've had terrible experience correcting myself after...
first, thankyou, that someone would spend time correcting me,
so i thought that pions does have rest mass when they do, that's great news, i now know,
but now i'd like to know what are electrons then? and do they have the same source of mass as from protons?
and if so, how does proton have mass...
hi, I've heard that protons has most of their mass from their electromagnetic and strong interactions between their quarks, but specifically, how does that make mass? and if so, what is intrinsic mass then?
and pions has 2 quarks and strong and electro interactions, why doesn't it has mass...
hi, I'm currently talking about light, and I'm trying to find out if there is a material or a method that can flip a polariser's polarisation...
ie, if i apply a current, then this crystal changed from a clockwize polariser to an anti-clockwize polariser, and it is either a plastic or elastic...
i am wondering would that be possible to make a prince rupert's drop with metal..
would it end up having similar properties? (ie high compressive stress => stronger) or does molten metal flow too quickly?
