England yes students foreign completed completed mom completed mom yes this is very very exclusively for neet 2024 okay 11th topics yes foreign foreign applications of Dimensions okay so let's start let's begin chat foreign yes eight months foreign abdina next so next day in our discus pandon our physical quantity physical quantities people okay so in the measurable physical quantities come on if it is very clear come on do it yes upper physical quantities but it is so let's go further upper in the physical quantities love fundamental physical quantities okay miracle amount of substance angle between two lines foreign foreign foreign foreign we can go for the next one yes ma'am now solid angles okay so song with angle sub D9 and now were complete three dimension okay our complete three dimensions okay okay concentrations okay because physical quantities will be greater than units foreign okay yes foreign kilogram yes it is seconds okay it is what are the advantages foreign foreign should be smaller letter okay okay other than that in the kilograms it will be in a small letter okay so this is very important yes I hope it will be because lot of effort foreign foreign to syllabus okay minus is foreign foreign foreign foreign diameter of a planet measuring of diameter upper measuring of diameters done that is D into a u small D into D correct in the Pocket Edition it should be in radians come on this is very important okay very important okay ma'am today Wednesday okay okay okay fine fine degrees degree highlighted foreign okay foreign yes cool where we can get the PD of ma'am we you people can get the PDF WhatsApp Community Labs okay description box okay so let's go further Dimensions Dimensions dimensions foreign that I'm not a Dimensions upper Dimensions when the internet has seven dimensions are literally important length Okay temperatures okay so these are important gravity is nothing but relative density the relatives relative density fluid mechanics okay foreign trigonometric formula solid angles angles efficiency so give up a maximum on the dimension okay clear our yes so next let's move for the next one Dimensions it's very important listen carefully okay and now Dimensions Dimensions always work under hard work mechanical terms dimension so this is very important so power will be equal to V into I here the gamma power will be equal to V into is your mechanical one okay Power updating it's a mechanical thing so power which is foreign same dimensions minus 1 okay sorry angular velocity inverse of angular velocity resistance speed of light will be equal to the velocity okay velocity speed of light is your relative permeability relative permittivity okay one so that will be equal to the speed of light and will be equal to the velocity okay so up in the tricks foreign so now the next one application of dimensional analysis to derive a formula the dimensions to check the consistency of a dimensional equation to check the consistency of a dimensional equation is to derive a relation between two or more than two physical quantities okay ma'am foreign for example for example V is equal to U plus a t update is momentum will be equal to mass into velocity in a very multiplication changes for example X is equal to Y plus X is equal to Y minus foreign so dimensional analysis that can be written as K into Dimension as K into K into foreign so if foreign so velocity what is the l l t power minus 1 will be equal to acceleration l t power minus 2 either time so T power 1. l t power minus one and that is okay dimensionally correct meaning clearer okay and in no important X is equal to Y plus that is how to find LTE map so listen velocity formula another velocity or the Formula One the displacement divided by type okay displacement obtain another meter upper meter Dimension another l time now second second order Dimension t t upper denominator the numerator l t power minus one L T power minus one clear icon so these are important okay done it's it's done let us practice a previous year numerical okay why in the numerical engineering 100 clear idea we will be using it okay so be strong okay but be strong so now V is equal to V is equal to ax divided by B plus T okay find a and blessings okay now I will try okay now on the on the video okay definitely it will be also useful okay wow don't worry rules which is time let's find a okay V is equal to ax divided by either one the T okay the answer foreign can get these are very important points the next one what we have to learn is it cannot derive dimensionless functions okay dimensionless functions like sine Theta cos Theta the trigonometric values E power x is foreign okay so next set of questions next set of properties in enabling or The discus can only check dimensional validity but not exact relationship between physical quantities correct exactly okay it cannot derive formulas with plus and minuses it only works when a quantity depends up to three physical quantities yes done done clear our calm yes so p y q is so this is another one question is just answer this answer the center requested okay what they have given up the velocity V of sound in a gas depends upon its pressure p okay so velocity is p is equal to Velocity will be equal to root of P divided by rho updating yes okay now listen carefully upper velocity will be directly proportional to P into rho okay well the dimension character in the dimension character started do it now this one so first velocity above V will be directly proportional to in the P rendering terms will be directly proportional to P can opener the pressure right angle pressure right so pressure m l power minus 1 T power minus two whole power Alpha okay density density density is very EC mass by volume upper row will be equal to mass by volume and the L power three yes or no l power three minus 3 okay so m l power minus 3 into beta okay so if an extent is because is directly proportional to L power minus Alpha minus 3 power 3 beta negative T another T power minus 1 will be directly proportional to T power minus 2 Alpha of D negative right same base minus 1 is equal to minus 2 Alpha denotative right minus minus Alpha will be equal to 1 by 2 Alpha is anything power zero will be one yes or no anything power 0 will be what upper Z 0 is equal to Alpha plus beta dedicated upper Alpha will be equal to minus beta beta will be equal to minus okay beta will be equal to minus Alpha so beta will be equal to minus 1 by 2. we will be equal to P 1 by 2 rho minus 1 by 2 a pie the denominator power plus side yes or no so that will be P divided by rho whole power one by two one by two one or maybe here so finally we can write root of P divided by rho finally we can write root of P divided by rho a person is come on do it yes okay um so definitely we can rock how many of you are there yes okay done super foreign not allowed foreign okay foreign first step s 4.72 4.89 4.82394 [Music] okay now original value original values closer accurate in the values yes foreign [Music] yes so this is this is what you call the Precision okay okay yes yes absolute absolute error absolutely it's nothing but original value measured value okay one I'm going to measured value clear outcome absolute error okay in the measured values absolute value so total value divided by total time foreign for example kinetic energy is [Music] [Music] foreign foreign foreign beta so Del B divided by B the denominator is Del C divided by C Delia a plus b plus r minus Adam okay so or if normal or questions [Music] Del C divided by C into 100 plus del d divided by D into 100 okay one percent so three into one plus Del B can equal to so 2 into 2 plus 3 plus 4 plus 3 plus 4.7 so 14 percent 14 percent is that cleared yes so it is 14 okay yes foreign what is my question is foreign numbers exact numbers so exact numbers foreign significant number infinite significant number okay okay infinite significant numbers okay so that's how it happens so that is exact purpose significant figures foreign [Music] decimal decimals okay yes now leading zeros with are without decimal are non-significant 13.0.074 um leading zeros leading zero subdina decimal points now topic application rules and regulations foreign okay and the five for example fourteen point six seven five okay number another odd numbers foreign foreign around okay final answer thank you so much thank you so much mom so are the Exacta 500 cup I'm not bald okay exactly it is odd number right okay yes that's it okay give me another 15 minutes I will done I will be done okay yes that is enough okay well that is 0.01 millimeter 0.001 centimeter foreign division this is pitch foreign foreign okay done done okay please check out okay so pitch divided by number of division on the circular scalar least count oh my God marked is less than 200 very depressed ma'am no music inside why depressed see attend a Great Indian battles okay we are here no wife here okay foreign that is foreign 33 . 33 into least account foreign [Music] it is foreign okay positive three into least count okay foreign foreign [Music] program Solange how to study Physics in book uh videos the pitch of the screw cards will be we people know least count is equal to pitch divided by number of Divisions 50 divisions so that will be 0.5 millimeter right the perfect answer will be option b clear ARCA yes now clearance sessions okay we will plan then thanks for remembering that okay done done yes so now now ma'am what's up pdf what's up yes 0.01 centimeters foreign yes foreign it is important okay done up a total reading English scale division into least count minus zero error into least count okay okay so first will be very near caliper will be 1 MST minus one VST one MST minus one VST the first Formula inner formula nvsd will be equal to n minus 1 MST correct n v s t will be equal to n minus one VST will be equal to n minus 1 divided by n m s t correct substitute will be equal to 1 MSD vs minus n minus 1 divided by n m s t up in MST what will happen so that will be MSD n minus n plus 1 divided by n n so n n cancel it divided by n update Q is another number of Divisions on the Vernier scale okay yes foreign foreign foreign foreign [Music] foreign foreign if the smallest division on the main scale is half the millimeter is half millimeter then very near constantis Varina constant updinger the least about least the smallest division in the main scale so that means the smallest division the smallest division is half the smallest division of Dinger than the half so small is the full of one centimeter one millimeter of dinner the kutti values zero point half the millimeters 0.5 millimeters the smallest Division and the smallest division is T can be written as nine by ten MST what will be the value foreign [Music] yes yes yes very easy okay any doubts any doubts so far foreign done done yes oh you missed my class no problem next time okay yes yes so this is going to be the homework question any doubts any doubts any doubts any doubts okay in no time rounding off okay okay [Music] how many of you are feeling confident foreign yes [Music] foreign it's a very golden opportunity that you people can have an idea okay okay yes yes foreign done yes so thank you so much because this is okay so take care everyone have a great day this is okay so bye everyone take care have a great day now come [Music] bye everyone
