Nothing.

Please I am talking about waec exam and what about chemistry practical

@@yousciencelab5307thank you

@@PeterAborash-dw6gp no issues. There's no problem with that.

@@SalamNuru okay

Please do you have a video for how to plot the graph?

@@SalamNuru yes

@@JosephDoris-id9wm I don't know. This is just a guide.

@@MercyEmokpae no problem. As long as you got the scale right on your graph

@@Qween.P no one will ask you that. It will be given

Thank you sir

@abuhjohn8688 you can tell your English teacher to teach you letter formats or you can use Google to search for addressing formats. Thanks.

@@yousciencelab5307 thanks sir, but I meant the address on the Microsoft word in the video (sender's address)

@@EdiriEmmanuel I don't do biology. I'm sorry.

@@BlossomOladapo-yc7sx yeah.

@@yousciencelab5307 Sir just to confirm the graph we were asked to plot is it positively sloped or negatively sloped

@@BlossomOladapo-yc7sx I didn't plot it. But I think it should be positive

@@yousciencelab5307 ok thanks a lot sir once again I appreciate 😊😊😊😊

@@BlossomOladapo-yc7sx you're always welcome

@@AfamefunaEmmanuel-jb6sc I'll try. When is the exam?

@@yousciencelab5307 thank you sir The paper is on Monday 1st of July

@@Al-ameenMuhammad-ut1gm it depends. But you can get up to 10 marks.

You can get all marks if you do the right thing. Put in the right units, the right decimal placces/significant values, and the required number of quantities that are supposed to be on the table.

Thanks sir

@michaelkayode9912 I'm sure NECO cannot ask you to provide masses which cannot make the whole system stay balanced. Remember, the set of masses must be able to balance each other out.

@@SmilingFieldHockey-em7rm that's because if the mass is 70, it will pull the 30 g mass up. So, it won't work for 70 g. If the mass is greater than 30 g, 70 g will work

@SundayEzeh-cs4nj it wasn't assumed. I first converted it kilogram by dividing by 1000 and then to newtons by multiplying by 10. It will still work even if you don't convert it. You can just leave the masses like that.

@klassy_joanna maybe you can show it to someone who can explain it clearly to you. 😃

@@annfashioncreativity7645 try and increase the volume of your device.

@@abdulmuizzsali I'm glad to hear this.

@@SamuelStephen-gd3py you saw it in the video.

@@AmaechiJeffery check your physics textbooks on how to resolve vectors.

It has to be. First of all, the length AC is not the same in both videos. Secondly, the manipulated values are more accurate.

That's true. Because of the time and length of the video. All what you can do when the voltmeter is connected across the series connection is just to add the two resistances to gether and then apply V = IR.

@tunjiagbola4751 anything is possible.

@@Vision20k good morning. Thanks for your kind words.

@okoliepromise807 no. It's not necessarily so. Different resistances can be connected in series or parallel

@@chijiokeemmanuel9265 I appreciate your comment. Thanks.

@tundeadeleye1000 of course, it won't work because a mass above taste would slide the 30 g mass up.

For it to work, the 30 g mass has to be higher.

@@yousciencelab5307 what can I do since neco gave 30g as the fixed mass. And the question might probably require the use of a larger mass. Is there any other formula I can use because when I tried the formula for the angle you gave,it was math error.... Is there any other formula for that sir??

@tundeadeleye1000 If the fixed mass is 30 g, then NECO would provide masses that will fall in the range where the formula will work. For example, if Neco gives masses like 40, 50, 70, 90, 110 or 130, it will be advisable to use 100 g as the fixed mass. If you use a smaller mass like 30, 40 or 50, it won't work. This is because, the bigger masses would just drag them up the pulley.

The 30g mass is fixed and does not change

Yes, the tension varies due to the masses. That's why the angles change.

@@Omez213 I held the pulley to the clamp.

@@OdebiyiMichael-wp1ej God bless you too.

@@SamuelStephen-gd3py yes. Search through my channel to see it.

@AkogwuMoses-cc9qd I think it's good to add it. Here is what you can do. Look for a question on electricity where the emf is 2 or 3 volts. Check the internal resistance given in the question. Use it as the internal resistance of the battery.

@@yousciencelab5307 okay.. thank you very much
