Newton's 4 law😄😄 = Every book continues to be at rest and covered with dust until and unless internal or external exams appears. The speed of page turning is directly proportional to the syllabus to be covered, but tension remains constant.😂😂

Koun koun ye lecture 2024 me padh rahe hai and class 9th me ✋🏻

[Lanadelreydaughter]

Its 9th and im very excited to start the first chapter of physics 👻
I hope i do well in this class
Best wishes to everyone who are starting a new session in 9th 💗

NITSE Numerical
3) distance=33cm
displacement=7√2
4)distance=44cm
displacement=0(as it came back to its initial point)
Hope this is correct!

[harshking]

3.Distance = 3/4 × 44cm = 33cm

Displacement –:
7cm² + 7cm² = s²
98cm² = s²
s = 7√2 cm
4. Distance = 2πr
= 2 × 22/7 × 7cm
= 44cm
But, Displacement will be zero because object return back to its initial position

[AyushJaiswalOG]

NTSE Numerical –:

3.Distance = 3/4 × 44cm = 33cm
Displacement –:
7cm² + 7cm² = s²
98cm² = s²
s = 7√2 cm
4. Distance = 2πr
= 2 × 22/7 × 7cm
= 44cm
But, Displacement will be zero because object return back to its initial position

Hope! This is right! 🥰🥰

His teaching is quite funny, btt literally legendary teacher..🙌🏻😂😂

[Aesthetic-k]

3. Distance = ¾(2× π × r)
¾×2×22/7×7
= 33cm
Displacement = (H)² = (P)² + (B)²
H² = 7² + 7²
H² = √98
= 7√ 2 is displacement
4. Distance = 2πr
2 x 22/7 x 7
= 44cm
Displacement = As we know initial and final point are same displacement turns zero

Challenger problems
1. Displacement can be zero if the initial and final point of an object is the same
2. C. Displacement < Distance always but sometimes when distance and displacement both are covered in a straight line the magnitude becomes same but displacement can never be more than distance and distance can never be less than this displacement
Tysm for the amazing session sir
😊😊

Kon kon summer vacation me padh rha hai 😉

[a-ll.subj_]

3) solution:
3/4 ×2×22/7×7 =33 cm
Displacement 7 root 2
4) solution:
3/4×2×22/7×7 =33
Displacement= 0 because final and initial point are same

[sarvatha]

Thanks for explanation sir....
Answers are....
1-) morni hill is in haryana, india.
2-) in 3rd question, distance = 33cm
And displacement= under root 98 cm
3-) in 4 question, distance =44 m
And displacement = 0m
4-) yes. The distance is always positive but the displacement May be positive, negative or 0.
5-) displacement May be equal to distance, often distance is greater than displacement so hence last answer is option number D .

[bandayayan]

3) Distance= 33cm
Displacement=7root2
4) Distance = 44cm
Displacement= 0

[UshaDevi-pxtj]

Q1
Answer - Yes, an object has moved through a distance can have zero displacement if it comes back to his intial position.
Example- If a person jogs in a circular path which is circular and completes one round. His Intial and Final position are same.
Thus, his displacement is zero.
I had learnt this question and answer from book.

[Anwesha]

47:05 𝘾𝙝𝙖𝙡𝙡𝙚𝙣𝙜𝙚𝙧 𝙋𝙧𝙤𝙗𝙡𝙚𝙢-
𝙖. Yes! An object can have a 0 displacement when it travels in a straight line or it's initial and final position are the same
𝙗. d.Displacement≤Distance

[allisallowedhere.]

Ans.3. Distance=33 cm
Displacement=7 underroot2
Ans.4. Distance=44 cm
Displacement=0 cm

[Anwesha]

46:11 3:- 33cm (distance)
7√2cm (displacement)
4:- 44cm (distance)
0 (displacement)

Main class 8th tak physics par dyan nahi deta tha par aaj pata chala main galti kar Raha tha From now physics is my one of the favourite subject. Thanks sir thanks a
lot.
