00:00:00Come on, let's move on again, percentage question. Now there are two questions in this way. First of all, let me tell you, stretching the word, stretching the word, stretching the word, you should have three formulae, R is proportional to L square, R is proportional to area square, R is inverse proportional to R key power.

00:00:27But, you need to remember this. Now, percentage questions are good. Now, let's do them properly. There are two types of 5% to less and 5% to less.

00:00:42The important thing is, stretching the word, the length increases, the radius increases, the resistance increases, but what does not change?

00:00:54Specific resistance. Specific resistance remains same.

00:01:05This stretching does not change.

00:01:24This stretching does not change.

00:01:31This stretching does not change.

00:01:33This stretching does not change.

00:01:37Byronas, it is a good point.

00:01:38It is a good point.

00:01:39This stretching does not change.

00:01:40It is a good point.

00:01:41It is no more, it is not undesirable to be.

00:01:42In fact, we will try to dominate the word and it is not積極其ua.

00:01:46I have to do better outline the word.

00:01:47To determine if the word is not changed.

00:01:48It is a good point.

00:01:49It is a good point.

00:01:50It is not 죄 and Yadda, it means nothing is in it.

00:01:51It is a good point.

00:01:52It is not worth shedding.

00:01:53So, this stretch, the number of 0.

00:01:54It is not a good point.

00:01:55It is a good point.

00:02:00It is a good point.

00:02:02sabhi log board pe d eckhen 5% se kum ke sawaal ko kiase handle giya jata hai woh d eckhiye

00:02:08yye puri physics me eek jiasa tariqa hai puri physics me kahi bhi sikhenge eek jiasa

00:02:13eek bada dhimag mein bethaiye jiasse koi relation likha x barabar a square b cube upon root

00:02:21c koi man se ligh diya teira meira sabhi log board pe dhiyan dhe bhoat aaj ka lecture

00:02:26asan hai khushman se samajh me a jayega root ka matlab kya hoota hai power half power ko

00:02:34kaan le jayen upar a square b cube c ki power minus a ab bataiye ab mujhe likhna hai

00:02:42padhiyan dijiye kab tak laghegi trick 5% se kum tuk x ki jaghe likhenge delta x by x into

00:02:51hundre dh jobhi power is ko aage liya hai kitna two delta a by a into hundre dh jobhi

00:02:59power hai 3 plus ka 3 minus to minus hi aega jobhi power hai jaisi power hai wiesa hi

00:03:13ki aage aage aage ga ye kia kalata ye ye is poor ko bolte hai percentage change in a is poor

00:03:24POURYEH KO BOLTAY HAH PORCENTARY CHENGE IN

00:03:41I will write 2-3 times more, see, if you write later, you don't have to write attention.

00:03:48Now, there are stretching questions.

00:03:50So, first of all, R is proportional to LSO.

00:03:55Look at this, every child can understand.

00:03:58Physics, you know that physics is the most difficult thing in three of us.

00:04:02We will give attention, we will study, then we will not study.

00:04:06We will not study, we will further away from physics.

00:04:08We will go, there will be depression, there will be anxiety in the subject.

00:04:13If we study, we will not study.

00:04:15R is proportional to LSO.

00:04:17Now, 5% is less.

00:04:20Let me tell you what to write.

00:04:22Delta R by R into 100.

00:04:25Power to go.

00:04:28Delta L by L into.

00:04:31This is what is?

00:04:33Percentage change in L.

00:04:38We will write.

00:04:39We will write.

00:04:40We will write.

00:04:41We will write.

00:04:42Area of square.

00:04:43This will go up.

00:04:44Minus 2.

00:04:45Tell us how to write.

00:04:47Delta R by R into 100.

00:04:50Minus 2.

00:04:51Delta A by A.

00:04:55Minus.

00:04:56Minus.

00:04:57Minus.

00:04:58And see, sir.

00:04:59One more time.

00:05:00R to power 4.

00:05:02U will go up.

00:05:03The power.

00:05:04Delta R by R into 100.

00:05:07Minus 4.

00:05:08Delta R by R into 100.

00:05:09Minus 4.

00:05:10Delta R by R into 100.

00:05:11It's what is?

00:05:12It's what is?

00:05:13Percentage change in radius.

00:05:15This change in radius.

00:05:16radius and this is the percentage change in resistance.

00:05:23If you have three questions, it is very easy.

00:05:32What do I do here?

00:05:34You can learn every chapter.

00:05:37But when will it be?

00:05:39I have written two times so that you are thinking

00:05:42if you have 5% more, you will leave it?

00:05:46No, I will give you a different way.

00:05:48Who is going to do this?

00:05:505% less.

00:05:52I will write.

00:05:58Three of them do not do it.

00:06:00Three of them do not do it.

00:06:02Five of them do not do it.

00:06:04Five of them do not do it.

00:06:06I will write.

00:06:08I will write.

00:06:10Five of them do it.

00:06:12I will write.

00:06:14I will write.

00:06:16This is very easy.

00:06:18I will write.

00:06:20They are very easy.

00:06:22It is very easy.

00:06:24Conceptual.

00:06:2620-25 numerical.

00:06:28Error.

00:06:32this is the error. This is the percentage change. When we read the error,

00:06:38the error is the error. What is the error? The error is the percentage change.

00:06:44So, the percentage change is the percentage change.

00:06:48I will do it.

00:06:50I will do it.

00:06:52I will do it.

00:06:54Now I will write two questions.

00:06:58First.

00:07:02...

00:07:12...

00:07:16...

00:07:20...

00:07:26...

00:07:28.

00:07:58.

00:08:00.

00:08:04.

00:08:08.

00:08:12.

00:08:16.

00:08:17.

00:08:18.

00:08:19.

00:08:20.

00:08:21.

00:08:23.

00:08:25.

00:08:27Now, see, you don't have a problem. In the paper, there will be a lot of questions in front of you. How to show you how to show you how to show you how to show you how to show you.

00:08:39Like, Google Navigation, Google Maps, then how to navigate? One thing you can understand. First of all, you have stretch. Stretch comes in the mind. L square, A square, R to power 4.

00:09:00So, this is how it works. First of all, Google Navigation also works. First of all, you have stretch. Stretch after three formulas. Then, you have long.

00:09:11That means, long formula. Then, you have 5% from less. Then, you have 5% from less. Where do you take power?

00:09:22L k e s e s e s e s you n a t b p poundnay ka anand a t a t a y s e s e t na conceptual. Stretch d eekha, lombai d eekhi, 5% se kam deekha.

00:09:34دیکھا अब बताईए डेल टेल कितना है तीन तीन नहीं इंक्रीज प्लस तीन अब बताईए तीन दोना छे तो परसंटेज

00:09:46चेंज इन रइस्टेंज छे परसंट इसमें मझा आएगा stretch area आएगा तो a square ऊपर जाएगा तो a की power minus 2 तो delta r by r into 100 minus 2 delta a by a into 100 अब बोर से देखना उसने क्या किया है

00:10:14थिनर थिनर थिनर का मतलब पतला पतला का मतलब area कम हुआ है बढ़ा है तो द्यान से देखना यह minus यहाँ भी यह minus और आएगा पूछो यह minus क्यों थिनर हो गया

00:10:34बस चलो ठीक है ठीक है देख लो एक minus यह और आएगा यह minus तो आया फॉर्मूले का और वो minus और आएगा क्यों आया क्योंकि थिनर area क्या हो गया कम

00:10:53तो answer आएगा plus का .2 तो सब नहीं लेता तो minus का आ जाता भाई वो दो option देगा

00:11:02.2 increase .2 decrease तो plus .2 का मतलब है increases by .2 इसलिए sign का महत्व है

00:11:14plus का मतलब आएगा answer में increase by 0.2

00:11:20तो इस minus पे ध्यान दीजिए, इसको style लगा लीजिए, ये minus गलती नहीं होनी चाहिए

00:11:34तसली से देख लीजिए, दो minus समझ में आ गए, एक minus तो formula का है और एक thinner का minus है

00:11:42ये है profile number 1, ये क्या है 5% से कम, अब लिखिए line change करके profile number 2

00:11:52अब लिखिए profile number 2

00:11:56profile number 2, 5% से ज़्यादा

00:12:05इन सवालों का तरीका handle करने का लग होता है, कैसे एक सवाल करके देखते हैं, तब समझ में आएगा

00:12:16अब वायर
