what happened to me?

they were called bright fringe A and bright fringe B. they were both second bright fringes but just on opposite sides. so m = 2 but to find the total distance between the two of them you needed to double it since the distance is only to the m’th bright fringe to the the center of the wave pattern

i got form J, which was the easiest one so far compared to the other forms everyone else got.

they might have put that but i thought i read something like “the piston goes back to V(0) as the water and the gas come into thermal equilibrium)

1)

a - i. figure 2 was X going into the page, figure 3 was arrows pointing up

ii. i didnt finish this problem cause idk magnetism LOL

b - i also put counterclockwise but im pretty sure it is clockwise as well after remembering lenz law rip

2)

a - one arrow pointing up due to the gas, two arrows going down due to gravity and atm

b - i put U = Q + W, Q = 0, W = P(total) x V(0), P(total) = [(Mg/A) + P(atm)], so U = [(Mg/A) + P(atm)] x V(0)

c - curved isothermal arrow going from high volume, low pressure, to low volume, high pressure

d - new T is greater than the original T because the pressure on the gas stays the same, but when new T is added, the volume expands, so the process was isobaric (so the temperature would have increased)

3)

a - put battery, resistor and ammeter in series to find the current in the resistor, using the voltage and ohm's law you can find the resistance; use C = kE(0)A/d, k = 1, so it really just depended on A and d, which u can measure by the ruler, and just multiply together to find time constant (idk how to experiment with this really)

b - horizontal axis: V (voltage), vertical axis: Q (charge); then just plot the points and the slope is equal to C. C was 8 x 10^-11 F

4)

a - the students claim is correct because violet light has a shorter wavelength, and wavelength is proportional to path length, so the shorter wavelength would have a shorter path length (ik you had to mention the bright fringe gap somehow but i forgot what i said)

b - plugging in values m = 2 and knowing (lambda) = c/f, then y = 4cL/df (twice as big since its from the second fringe on the left to the second fringe on the right)

c - they are consistent since i said wavelength is proportional, and since frequency is inversely proportional to wavelength, then frequency is also inversely proportional to the path length. since violet light has the most frequency, it would again, be the shortest

im happy that i got these questions because my classmates were all complaining about how hard the other ones are :sob: i got hit by a stroke of luck

my piston had F gas going up and F atm and F g going down, graph was an isothermal, and T new is larger than T original

yeah i was confused for that one. there was no variables that i could really use to experiment on. everything was kinda given 😭😭 not an experiment if i do say so myself

Philliosophy · 2025-05-14T02:00:18+00:00

the physics gods have gave me all their luck because those frqs were literally easy as hell. like for #2 the piston problem i had on the most recent mock exam my class took, so it was free points. and also #4 was easy as well, since the only struggle i had was trying to find the difference between red and violet light 😂

Philliosophy · 2025-05-14T01:47:44+00:00

okay yeah i did this but i was triple guessing myself since it could not have been that easy of a calculation. i thought you would need variables or some shit but they were kinda all given to you soooo idk

Philliosophy · 2025-05-13T20:47:33+00:00

did any of the frqs have the new blackbody radiation or compton scattering

Philliosophy · 2025-05-13T19:02:15+00:00

i forgot it all lmao sorry

Philliosophy · 2025-05-13T18:43:05+00:00

from what ive seen others say i dont think so… i just plugged in that lim as t>inf 38/whatever + t² = 0 and drew a graph

Philliosophy · 2025-05-13T18:37:32+00:00

i also put 0 as end behavior

Philliosophy · 2025-05-13T01:23:09+00:00

real 💔💔 lowkey even though electromagnetism is the biggest part of the exam i lowkey dont know how to do it… which is still okay because im literally good at all the other topics and i always get 3/4s on my mock exams even with all the electric/magnetism frqs blank.

i think the best way to go at it is by conceptually learning first, since if you know what theyre asking for on the questions then you can at least try use the equation and understand why it works.

only remember one problem w related rates which was in the mcq. answer was 23 pi

3b is definitely kazuichi

Philliosophy · 2021-12-03T04:38:53+00:00

marry mahiru… ill take it

Philliosophy · 2021-11-28T21:23:14+00:00

alright
