For m=-3 (Real and Inverted)
-3=-v/u
v=3u
Putting this value in mirror formula we get-
-1/20=1/3u+1/u
-1/20=4/3u
-3u=80
u=-26.6cm 1:31:23

Hw answers ~
1:31:45 u= -80/3cm v= -80cm
1:47:27 f= -1m
b) avg spd= 1/150 m/s
c) avg spd = 1/60 m/s
d) avg spd= 1/10 m/s
2:05:06 v= -1/180 m/s

[navyakunwar]

1:47:37
=> 1/f= 1/u+1/v
1/f=1/-1.5-1/3=-1/1
:- Therefore {f=-1m}

1:57:31
=> b) at u=-29m
V= uf/u-f= 29/30m
AFTER ONE SEC.
u=-24m
v=24/25m
Difference in position of image
24/25-29/30
-7/50
Average speed=∆v/∆t
=-7/50÷1=[-7/50m/sec]

c) at u=-19m
V= uf/u-f= 19/20m
AFTER ONE SEC.
u=-14m
v=14/15m
Difference in position of image
14/15-19/20
=-1/60m
Average speed=∆v/∆t

=-1/60÷1=[-1/60m/sec]

d) at u=-9m
V= uf/u-f= 9/10m
AFTER ONE SEC.
u=-4m
v=4/5m
Difference in position of image
4/5-9/10
-1/10
Average speed=∆v/∆t
=-1/10÷1=[-1/10msec]

2:03:43
=> f=1
u=-29
v= 29/30
m=-v/u =-29/30(-29)=1/30
Vi=-m²(Vo)
=-(1/30)²×5=> -1/180 m/s

All the best everyone for your upcoming exams 🙂✨✨

[Rubixkov]

3:13:00 Critical Angle =48°
Refractive index =1.35

[srishublink]

01:30:52 Problem 2) For real and inverted image, u= -26.67cm

[suyash_]

1:31:30 For the second part u = -26.6cm
1:47:30 focal length = -1m
1:57:45 (b) = -1/150 m/s
(c) = -1/60 m/s
(d) = -1/10 m/s
2:5:10 instantaneous velocity of image = -1/180 m/s

[kanikakumari]

1:31:43 problem 2) For real and inverted image (m=-3) then object distance (u)= -80/3=-26.6cm
1:57:25 ∆v/∆t= (b)1/150, (c) 1/60, (d) 1/10

2:05:11 Instantaneous velocity of image when jogger at 29m is -1/180 m/s

HELLO GUYS FOR THOSE WHO DON'T KNOW THIS VIDEO IS JUST PART ONE
He did'not mentioned this as part 1

[akshu_musical_oasis]

2024 budies🎉....🥱 attendance 🙋🏼‍♀️here ...

[AdityaKumar-ered]

1:35:17 1/f=1/u+1/v
--> 1/f= 1/-1.5 + 1/-3
--> 1/f= -1-0.5/-1.5
--> 1/f= -1.5/-1.5
--> f= 1✓✓✓

2024 CBSE board wale attendance lagaye😢.. 😅

[kidstube-upsf]

Perform best in boards and make parents feel proud ❤😊

mirror formula- 1:01:40
reln b/w real and apparent depth : 2:34:00
reln b/w critical angle and refractive index -3:00:00

[zvgjkkh]

All my juniours studying from him let me tell you one thing that this is not one shot this is three shot guys but he is teaching very good so make sure guys to study atleast 2 months before exam to score good best of luck

1:31:32 -26.6cm
1:47:33 -1m
1:57:36 -1/150, -1/60, -1/10
