A classic relative motion problem! Let's break it down step by step: 1. Person's velocity (v_p) = 4 m/s (horizontal) 2. Rain's apparent velocity (v_r_app) = 3 m/s (vertical, relative to the person) 3. We need to find the angle between the actual rain velocity and the vertical, with respect to the ground. To solve this, we'll use the concept of relative velocity. The actual rain velocity (v_r) is the vector sum of the rain's apparent velocity (v_r_app) and the person's velocity (v_p). Since the person is moving horizontally, we can resolve the velocities into horizontal (x) and vertical (y) components: v_r_app = 0 (horizontal) + 3 (vertical) = 0i + 3j v_p = 4 (horizontal) + 0 (vertical) = 4i + 0j Now, we'll find the actual rain velocity (v_r) by adding the two vectors: v_r = v_r_app + v_p = (0i + 3j) + (4i + 0j) = 4i + 3j To find the angle between the actual rain velocity and the vertical, we'll use the inverse tangent function: tan(θ) = horizontal component / vertical component = 4 / 3 θ = arctan(4/3) ≈ 53.13° Since we want the angle with respect to the vertical, we'll subtract the result from 90°: θ_vertical = 90° - 53.13° ≈ 36.87° So, the angle of the rain with the vertical, with respect to the ground, is approximately 36.87°.
27:40 They give wrong answer 3 times but i got it right @ once (ans is Neils Bohr) Bcoz I studied Atomic structure chapter from Alakh sir old vdos in those lectures Alakh sir tell this story💕 🙏 Thankyou Alakh sir 🙌 They are born genius still they are doing hardwork that's why they are on this position. Guys, we being the normal students must have to do hardwork to achieve success. ✨Thankyou 🙏
Kuch student aisa hota hai jo capable nhi hota itna bhi dene ke liye plzz alakh sir help sayad mai iski wajah se jee advanced Crack kr lu plzz alakh sir save one future
Alakh sir plzz help kro na ioqm ka batch mai capable hi nhi hu lene me plzz help kro na Alakh sir mai bahut sara video pe comment kiya pr koi help nhi kr rha you are last option for me sir plzz help me 😅😅😅 ya fir koi bacho se hi dila do mai bhi padhai kr liya karunga plzz alakh sir

Ye boht hi acha kaam he me ek civil engineering student or mene ye cheek 2 sal pahle Sochi thi ki apne field me bhi esa hi kuch hona chahiye or aaj ye dekh kr boht acha laga ❤
very brilliant show for educational purpose
Seriously, It was so interesting.
EVERYBODY HAS SPECTACLES
Except our alakh sir😊
thats what i too noticed🙂🙂🙂
Very nice intiative taken by PW It helps students to get better Thank you PW !!!
Continue it sir really 🎉 amazing such a wonderful ❤ 😃.
Great sir .Best wishes to all
All the best alakh sir
Sab ne chashme lagaye hai, one can imagine how long and tough they have been sticked to the books and study🥳
Isme khush kya hona kitni buri baat hai ki itne chote bacho pr itna stress dala jaa rha hai. Humans hai robot todi na.
Me after seeing the video: Who am i where do i stand 😢
I am topper of my class but 😢
Same😢😢
Same 😢
Iam same topper bro
Kismat science ko beat karte hue 😅
Especially pictionary round
lol this kid in -5 at 11:05 xD
Eveyone was wearing spectles❤

A classic relative motion problem!
Let's break it down step by step:
1. Person's velocity (v_p) = 4 m/s (horizontal)
2. Rain's apparent velocity (v_r_app) = 3 m/s (vertical, relative to the person)
3. We need to find the angle between the actual rain velocity and the vertical, with respect to the ground.
To solve this, we'll use the concept of relative velocity. The actual rain velocity (v_r) is the vector sum of the rain's apparent velocity (v_r_app) and the person's velocity (v_p).
Since the person is moving horizontally, we can resolve the velocities into horizontal (x) and vertical (y) components:
v_r_app = 0 (horizontal) + 3 (vertical) = 0i + 3j
v_p = 4 (horizontal) + 0 (vertical) = 4i + 0j
Now, we'll find the actual rain velocity (v_r) by adding the two vectors:
v_r = v_r_app + v_p = (0i + 3j) + (4i + 0j) = 4i + 3j
To find the angle between the actual rain velocity and the vertical, we'll use the inverse tangent function:
tan(θ) = horizontal component / vertical component
= 4 / 3
θ = arctan(4/3) ≈ 53.13°
Since we want the angle with respect to the vertical, we'll subtract the result from 90°:
θ_vertical = 90° - 53.13° ≈ 36.87°
So, the angle of the rain with the vertical, with respect to the ground, is approximately 36.87°.

Great Initiative by PW!
just imagine a JEE advanced topper is playing this game
❤what a match ❤
We want wallah schools and Khan sir universities
Sir me kese yaha aa sakta hu?
Mujhe qun smjh nhi aa raha h
kuch jyadda hi hoshiyaar bachhe hain very good
Don't feel us illiterate😂
Ohh yaar😢😢😢
meine socha tha ki inmo,inpho ke toppers hai
Unse kaam bhi nhi h
Maine bhi😅
@@ramnavalyadav635unka level janta bhi h tu😂
@@AnshPathak-qb4ge abe oo nsejs level 2 ka banda hu esse esse question krunga naa haath me aa jayega kya aukat
@@ramnavalyadav635OP
Three are my copititors
21:39 Cards Wale question ka answer toh option A hoga na😢
C(n, k) = n! / (k!(n-k)!)
where:
n = total number of cards (52)
k = number of cards to select (3)
C(52, 3) = 52! / (3!(52-3)!)
= 52! / (3!49!)
= (52 × 51 × 50) / (3 × 2 × 1)
= 22,100
Exactly
Yes
Ese bhi bachhe hote h...
Bhai sabke chashme lagree hai
Satvik wali team ko bhi kuch de dete 😂
Sir iski preparation shuru kaise kare
What does it takes to become like these students?
11th 12th ka syllabus 9th 10th me krna
Determination and enjoying the subject
genetics
Ek cheez observed kare ki sabhi ke akho me chasma lga hai.
Saro team hi intelligent but Red colour team ke dil or dimag dono baraa haiii.... intelligent❤
All questions are from ncert except few
🤓
These questions are easy tbh
I am sad for that red t shirt girl😢 because of that red shirt guy she failed to get first position
True😢
Feeling sad for red team❤
Yes because the deserve 1 rank because 😢
Kuch student aisa hota hai jo capable nhi hota itna bhi dene ke liye plzz alakh sir help sayad mai iski wajah se jee advanced Crack kr lu plzz alakh sir save one future
My score in rnmc level-1 is 96%
Time travel ke liye doraemon bana deta. Kya bhai...
kitab ke alava usne kuch nhi dekha hoga isliye doreamon nhi pata hoga 😂
33:20 bro wtf
Very nice intitative by PW !!
I also solved most of them 😁😁
22:40 this one
Explain plz
Card wala a hi hoga 22100
the red team was cunning especially the boy
he gave hint t osmosis see his lips
and even he wanted the other people to lose the game
WOW VERY GREAT
Good show please make more episodes @physicswallah @alakhpandey
Who am i😢
Mai 12 th ki student hu but mere ko bahut se question solve nhi ho rahe the 😢😢
Study like topper problem may be 😅
Wow
mere si sirf 5 questions ho paye
Reuploqd from jee wallah?
किस्मत वाले हैं because गट such exams
Very nice intiative by PW !!!
Well done pwian s
