This is what we called teaching .Some fun, some understanding, some questions relating to topic .Loved it

ELECTRICAL ENERGY CONSUMED = POWER * TIME
= 60*30*60
= 108000 JOULES.

[khushiraj]

Legends will watch this in FEBRUARY 🤟🤞🤞✌

[mayank]

Time is less for exam preparation, so preparation will also be time is proportional to preparation 😁😁😁🤣🤣🤣

[kothasmiley]

Me... Who is watching this before I day of exam... 😂😂

[riyachouhan]

Homework answer

Given P= 60W
T=30 minutes
So to convert it into seconds we will multiply 30 by 60
=1800 sec

Energy = P×T
60× 1800
=108000 watt
👍👍👍
The session was balle balle...
Superb sir superb

8. 40J
9. 6KW
10. Rs168

29:43 I did it without actually solving it! As if mass increases velocity will certainly decrease.
For eg. A fat person runs slower than a thin person as the mass is more in the fat person! 😂 Can this be true
Please reply

Kids watch it a month before their exam....men watch it a week before their exam.... legends watch it a day before exam....ultra legends watch it on the day of their exam....
I am a ultra legend...
It's 1 a.m. ...I am having my exam today 😂😂

[shrutivlogs]

y're the best sir....my favourite teacher ever:Abhishek find physics as a very tough sub but after watching your videos my concept of physics become changed😊

[shubhanshreeagarwal]

Vedantu, you really have amazing teachers. I've no idea how students like me could've made it through this session without you guys. Thank you so much. We owe you.

[samridhii]

Abhishek sir always makes the session so fun and interesting!

[fredricprabu]

Answer for the homework question is 1.08 * 10^5 joules . Loved the session . No doubts sir . You are rocking ! .

[girishrevankarr]

Sir I had a doubt
In zero work you gave an example of bag but the force is upwards and the displacement from the shoulders to the head is also upwards then how is it zero work

[yashu]

Very amazing session I have clear my all doubts. Thank you so much for this session sir
