You mean it doesn't work this way? Btw im so sorry. I need to seriously brush up my maths. And im already in F6

You don't have a reason make y equals to 0. Look at the following theorem. It is known as the Euclidean Division Theorem.

Will try to digest it, I guess. Thank you

The Division Theorem is prequel to the Remainder Theorem (you learned in STPM).

\
Yea, I do learn it in Math M. Failed that paper though lol. See if I can make up for it in the ulangan paper.

Thanks, I really need them. Anyway, can you upload the other 3 subjects of your trial papers(Maths T, Chemistry,PA) up here as soon as you get them? I really need to try them out.

Oh, for those of you that are taking the MUET speaking test on next week, I wish you the best of luck!

Thank you Critical_Fallacy and Just Visiting By for helping and giving out some advice regarding the MUET speaking section. Ever since my teammates and I implemented the language functions and the style/techniques that both of you introduced up here in this thread, our practice speaking session has a little bit of an improvement. The conversation has been a little smoother and it's been reassuring knowing on what we would want to speak on that exact moment and where will the conversation leads to.

Even a friend of mine who was stuttering long ago while conversing in English is now even able to occasionally use logical connectors and word linker in some of his sentences. It might not seem much, but it's already considered good enough of an improvement as for me and my teammates.

Glad I could help.

Being natural is often the best way to face a situation, even if it isn't a professional solution.

That's a good thing to hear. Keep practicing and they will never look at themselves quite the same way!

Critical_Fallacy, I have a question to ask.

Question: Two objects and of the same mass revolve round a planet in the same circular orbit, but in the opposite direction. When and collide and combine, what is the subsequent motion of the combined mass?

-From the above keywords, which is collide and combine, I know that this will surely be involving the principle of momentum, where the momentum of of a combination of 2 objects will be zero. But, why the answer for it is D, can you please further enlighten me?

Answers:


A: It will remain in the original orbit with the same period of revolution.

B: It will revolve round the planet in a smaller circular orbit.

C: It will move in an elliptical orbit with the centre of mass as one of the focus of the elliptical orbit?

D: It will fall down due to the gravitational field of the planet.(Correct answer)

Critical_Fallacy, I'm stuck with this question.

Given a series:, find the nth term,, of the series and what is the sum of the first n term,?

I was only able to do it until the second step:


=

The gravitational forces exerted by the Planet on the two satellites hold them in the same orbit but moving in the opposite direction (v and –v) around the Planet. Without thinking any complicated situation, this question is best answered using VECTOR ADDITION.



When v = 0, then a_θ = 0. Therefore, a = a_R.

Try this:



It looks a kind of arithmetico-geometric sequence.

So, when the momentum of the combined satellites are zero, it will not be able to resume it's previous circular motion around the planet. However it will be pulled towards the centre of the planet by gravitational forces, which in this case, is .

Thanks.

Hai.. Can someone help me to solve this question.. Question number 4(complex number)

Critical_Fallacy, I have some doubts in Physics that I have to clear off my find.

Question: A vessel contains 2 moles of helium gas, at 350K. The mixture is heated at constant volume to 400K. Calculate the total internal energy of the mixture at (a)350K and (b)400K.

-The answers for both (a) and (b) is and respectively. Where are my mistakes and errors?

My workings:
-(a)T=350K, f=5(since helium consists of diatomic molecules), R=8.31, U=?

-∴

-(b)T=400K

-∴

For ideal gases, the calculation for the internal energy is fairly straight forward.



An error is detected in the question. Helium (He) is a monatomic gas. Hydrogen (H₂) is a diatomic gas. The given answers cannot be accepted.

For Q4a, it is fairly easy to show



Please list the relevant formulas for dealing with complex numbers.

This is my Mathematics M trial question. I am from High School Klang.....
