Sorry sir, for the last question. The one you did was for the upthrust, the question was, "reading on the spring balance," Weight in air- the value you got, sir. 0.2-0.02= 0.18N
Weight of the brass in air 0.02kg × 10= 0.2N So when they said, the reading of the spring balance, when the brass is in a liquid, it means that, it experiencs an upthrust( a upward force), so the reading of the spring balance will be less than the actual value, and that is the calculation that the teacher did( the upthrust) So you would just subtract the actual value - and upthrust I hope it is clear now@@VictoryCyril-ld2tk

Sir, all the other tables i've seen usually don't have their weight in newtons. It's usually in grams. Ik the s.i unit for weight is newtons but even when you check the practical for waec 2000 physics they also left their weight in grams
Yea ..I saw it... Questions says you were given mass "record this weight as w1" mass & weight are not the same...so the recording in the past question is an aberration Also look at the table for the said year.....what they recorded for m(g) & w1 is the same ( makes no sense) Lastly spring balance doesn't read in grams ...it reads in NEWTON....
I feel honored Then for question 3 Electricity using meter bridge & Constantan wire.... your question is going to be a replica of WAEC 2008 PRACTICAL QUESTION 3....
The solution to the calculation is wrong We are asked to find the weight in liquid Which is weight in air - upthrust. What you got is the upthrust not the weight in liquid It's supposed to be 0.2 - 0.02 which is 0.18
With optics or prism comes a lot of error.. But if you are equal to the task...go ahead with it... But I advise question 1& 3 for question 3 Electricity using meter bridge & Constantin wire.... your question is going to be a replica of WAEC 2008 PRACTICAL QUESTION 3....
Sir please if the grams are given in 5g,10g,15g,20g,25g how do i comvert to newton Becuase when i tried comeverting to newton the table looked like a mess. Some of the values for kersone was the same with water. Sir please help, i need an answer before tomorrow🙏
Reason why I suspected 50g,100g, 150g...etc Talking about conversions... You will be provided with masses... Which you are to hang on the spring balance to get the weight in newton's [ alternatively, you convert the mass to kg by dividing by 1000... so since w=mg... get the weight & put in the table] The conversion is not something to worry too much about

Number 2 ...mirrors... comes with lots of errors... I'll suggest number 1(relative density or upthust) & 3 on electricity For question 3....check community post
Nope... density is directly proportional to mass [D=M/V] water has density m= 1000kgm-³ the liquid which is to be labeled L is (kerosene)-not to be disclosed has a density of 800kgm-³ . So, The mass in the kerosene & consequently the weight should decrease correspondingly So...weight reading on the spring balance for water should Norma be more than in the kerosene
Optics ... which is question 2... comes with a lot of errors... So advise that, you avoid 1 lecture video & 3 (2008 Q3 Waec past question) is your best bet to get ready for tomorrow
Intercept on the vertical axis doesn't happen in all graph......so nothing to worry over Then for question 3 Electricity using meter bridge & Constantin wire.... your question is going to be a replica of WAEC 2008 PRACTICAL QUESTION 3....
Masses given In the question in grams,you then convert to kg, & then to Newton using w=mg. Alternatively...just hung the Masses that will be provided in the lab on the spring balance & get the weightin Newton. In both cases w1 will be the same
In normal experiment....you just expect the spring balance to read less when mass is immersed in water & when immersed in liquid...due to UPTHRUST... when experiments was performed those figures were what we got... So in the exam tomorrow depending on the masses you are given... you follow same pattern & record things
W2 & w3 if you look at the instructions in the question displayed on the screen were the weight reading on the spring balance when the respective masses were hung & lowered into water firstly & then when same is lowered into liquid L.... w2 & w3 are merely spring Balance readings of the various masses
Thank you Sir But when conducting the experiment concerning W1 . Is it advised to weigh in air or convert to kg and multiply with acceleration due to gravity during the exam.
You can do any...& it should give the same answer... but being time conscious...convert & get things into your table from the calculator..

2008 Q3 ...that's a replica for your electricity question
Yes ooooooo
Sorry sir, for the last question. The one you did was for the upthrust, the question was, "reading on the spring balance," Weight in air- the value you got, sir.
0.2-0.02= 0.18N
Ok....that's an error from the editing team
Where did you get 0.2 from??
Weight of the brass in air
0.02kg × 10= 0.2N
So when they said, the reading of the spring balance, when the brass is in a liquid, it means that, it experiencs an upthrust( a upward force), so the reading of the spring balance will be less than the actual value, and that is the calculation that the teacher did( the upthrust)
So you would just subtract the actual value - and upthrust

Belated.....20g = 0.20N
Sir I got my slope to be 0.905 will they still mark it
I got 0.89
You got .
0.905.... your answer is perfect...±0.5... is ok
@@300plusacademy sir must the graph pass the origin
If it's comes with kg
You can't have kg masses in physics lab..
at this level...it's in grammes...
So u convert to kg by dividing by 1000
Then convert the mass to weight w=mg
or u just directly hang the mass on the spring balance & take the readings on it in Newton. In both cases the answer will be the same
Can I use the same digit you use@@300plusacademy
This is wonderful!
Thank you team 🤗🙌
Most welcome
Great job sir
But sir, is the reading of the spring balance not tension in string? Which is weight of object in air - upthrust?
On spring balance...
You'll see the graduation & numbers when using it...
