Q1) Mass- 20kg Uniform velocity- 6m/sec Ek = 1/2mv2 Ek = 1/2 X 20 X (6)2 Ek = 1/2 X 20 X 36 Ek = 1 X 20 X 18 Ek = 1 X 360 Ek = 360 J (Ans- 360 J) Q2) Mass- 60 Height- 10 Acceleration Due to Gravity- 10 Ep = mgh Ep = 60 X 10 X 10 Ep = 6,000 J (Ans- 6,000 J) Q3) Work done- 80 J Time- 10 seconds Power (p) = W/t p = 80/10 p = 8W ( Since we have cut both the 0s of 10 and 80 ) (Ans- 8W)
Certainly, here's a shorter version: In this scenario, although the initial and final momenta magnitudes are equal, momentum's direction changes as the ball moves up and then down due to gravity. Since momentum is a vector quantity, its direction matters. Thus, despite equal magnitudes, the changing direction violates momentum conservation.
Sir you too good .Iwas PW student but now I usually watch your videos because your videos are way much better then them .I usually get good marks in science but the chapter was never on my tips but now itis really on my tips your gives me satisfaction
Namste sir, I m doing the last math which you have given i saw many comments but the last math was not there so, if someone wants to do this so, i m showing them this one i m also a student i m 13 year old 😊😊😊... So/: Power of bulb=100 =0.01W.. Time used,t =8hr.. Energy= Power×time taken =0.01kw×8hr =0.08kwh =0.08 "units"... If someone is facing probl.(problem)in this math, can see this comment..... Mannu sir plzz give a life 😊😅

bhaiya apko kaise pata ki mera kal exam ha or mane bhi bahut work kiya ha 😅😂 acha chalu aap hee samose khila do mujhe or meri comment like kar ne wale ko 😇
Sir, According to Question
1. Ek = 360J.
2. Ep = 6000J.
3. P = 8 J/s.
3. The energy consumed
by the bulb 0.8 Units/Day.
Q1) Mass- 20kg
Uniform velocity- 6m/sec
Ek = 1/2mv2
Ek = 1/2 X 20 X (6)2
Ek = 1/2 X 20 X 36
Ek = 1 X 20 X 18
Ek = 1 X 360
Ek = 360 J
(Ans- 360 J)
Q2) Mass- 60
Height- 10
Acceleration Due to Gravity- 10
Ep = mgh
Ep = 60 X 10 X 10
Ep = 6,000 J
(Ans- 6,000 J)
Q3) Work done- 80 J
Time- 10 seconds
Power (p) = W/t
p = 80/10
p = 8W ( Since we have cut both the 0s of 10 and 80 )
(Ans- 8W)
Ye wrong hae

Right
How? Mera answer 180 aa rha h
23:25। In here mass- 20kg and velocity is 6m/sec
So
Kinetic formula-=1/2 mv2
1/2×20(6)2
1/2×20×36
Then
= 20×18
=360joule
Energy = 0.8unit. 40:03

360J answer
Mass of the object - 20Kg
Velocity of the object - 6 m/sec
Kinetic energy - 1/2 mv sq

1/2 × 20 × 36
10 × 36

Sir,
Ek = 1/2 mv²
So, m=20 and v= (6)²
Ek = 1/2 × 20 × 36
Ek = 10 ×36
Ek = 360

Mannu Bhai like Kara deya video ko and kinetic energy ma 2question ka ans hya 360J
24:22
Potential Energy = 6000J. 29:27
2nd question of kinetic energy the answer is 360joule
Sir
W= 80 , t= 10
Power= work done/ time or p = w/t
So, 80/10
= 8w
Ans unit m aaiga aur galat h

No your answer is wrong as 6²=6x6=36

3rd question power 8 w
kinectic enery = 360J
We can take g=9.8 answer would be 5880j
g=10 answer would be 6000j
sir given numerical answer is ; kinetic energy = 360 joules
Legends are watching one day before exam 🤣
Given: m=20kg
v=6m/s
K.E=1/2×m×v²
=1/2×20×6×6

Bhaiya correct hai ki nahi 😊😊
q1 ans 360 J
Sir our mass is given 20 kg and velocity is given 6m/sec so Ek=1/2mv square so the answer will be 60J
Sorry the answer will be 360J
1/2 × 20 × (6)2
10 × 36
Kinetic energy = 360 J
m = 20kg
v = 6 ms
Ek = 1/2 mv2
Ek = 1/2 × 20 × 6× 6
Ek = 1/2 × 20 × 36
Ek = 20 × 18 ( 2÷ 36 = 18)
