The Topicless Thread

[96NotOut]

It is but only when the object is falling freely.
When it's in another acceleration it's mass times acceleration.

I meant free fall. I asked cuz my teacher never let me use F=mg, even though g=a and all.

 

[Pakistani_Legend]

What would you reply to "You're a false caterpillar"?

I didn't get it.

 

[Haz95]

If I hit a 100g bottle with a speed of 10m/s using a 10kgs stick, why would the bottle go further than If I hit it at the same speed using a 5kg stick?

 

[Mamoon]

Details.

I didn't go to see her since morning. It's our duty to do so.

 

[Afridi96]

I'm Physics aqa unit 1 on Tuesday.

Alot of the answers are in the formulae booklet

 

[96NotOut]

You mean X and Y plates? Used to deflect the electron beam I think

Nope, it says X shift and Y shift.

Wait, I think you use them to provide the X and Y plates voltages... :/

I meant stating facts that you know lool, but hey asking questions might work as well.

I can use it any way I want.

^ F=ma

Yeah.

X plates deflect the e-beam horizontally and Y plates deflect vertically.

Yes, got that.

 

[Afridi96]

I didn't get it.

Oh it was a cuss in Shakespearian time, I remember in an English lesson once, we had to analyse what it might mean.

 

[Mamoon]

Yeah.


Yes, got that.

Sorry then.

 

[HamzaSaeen]

If I hit a 100g bottle with a speed of 10m/s using a 10kgs stick, why would the bottle go further than If I hit it at the same speed using a 5kg stick?

The force created by the 10kg stick is greater due to greater mass and F=ma?

 

[96NotOut]

I do.

Wow.

Masoom banne ki zaroorat nahi, hum sab kuch dekh rehe hain!

Okay...

By "hum", I hope its just you.

 

[Haroon786]

Exactly, but dw it's possible. I found out how important AS was this year ended up with a BBDE, ( I still plan on getting A*AA or better though, In'Sha'Allah)

You're retaking ?

 

[Mamoon]

Force will be greater and hence the momentum.

 

[96NotOut]

If I hit a 100g bottle with a speed of 10m/s using a 10kgs stick, why would the bottle go further than If I hit it at the same speed using a 5kg stick?

First off, you'll probably destroy the bottle with that stick.

I think it has to do with the mass. F=ma.

 

[Haz95]

The force created by the 10kg stick is greater due to greater mass and F=ma?

indeed...using the laws of momentum, the higher the mass the higher the force.
This is why its good to be fast rather than strong and bulky as you can improvise to make your fists heavier(gloves or something) whilst having a greater speed which equals a greater momentum which equals stronger striking power...therefore quicker people are more dangerous than strong people.

 

[Afridi96]

You're retaking ?

I'm not retaking the year, just some exams.

 

[Haroon786]

Sorry then.

Awkward.

 

[Haroon786]

Sorry then.

Awkward.

 

[Mamoon]

Really awkward.

My past papers book doesn't have a section on logic gates.

lol

 

[Afridi96]

Time to start some Maths revision If any of you have any Maths questions (preferably, differentiation/ integration - trigonometry) i'd appreciate it of you post it here.

 

[Pakistani_Legend]

If I hit a 100g bottle with a speed of 10m/s using a 10kgs stick, why would the bottle go further than If I hit it at the same speed using a 5kg stick?

The force exerted will be greater. The impetus will take the bottle further away.

The critical angle is the angle of incidence in the optically denser medium for which the refracted ray is 90 degrees.

Yes!

 

[Haz95]

lmao they are...I had to put the lol there cos I wanted to keep everything civil cos me and 96 have had loads of fights

 

[Haz95]

do the guys who are good at physics...generally, why is friction the centripetal force when a car goes around a roundabout...I don't understand this...Makes sense for tension or gravity but not friction

That's 2 marks in the bag for you (Y)

I did absolutely no revision for Physics, had 2 exams that day Have you done the June 2012 Paper?

 

[96NotOut]

InShaaAllah.

2/75...

Yeah i done most past papers i just wanna know generally as side info cos you don't need to kno

 

[Mamoon]

Why doesn't friction as the centripetal force make sense to you?

 

[Pakistani_Legend]

The centripetal force comes from friction between the car tires and the road. Friction causes the car to maintain its circular motion. The car would maintain forward motion instead of circular motion if the frictional force wasn't present.1

Footnote:-
1) For example, the car is hard to turn on ice because the frictional force is less.

getting schooled by a 14yo lol...Cheers and this is what i was asking mamoon

Yh I hear that, I was asking coz that was the paper I sat

 

[Pakistani_Legend]

Hi

Hello.

 

[Afridi96]

When you think you're ready for an exam but then you look at the June 2013 Paper

 

[Pakistani_Legend]

I went through the previous posts and I found out that Ikball was trolling us with his avatar.

 

[battler]

This thread is becoming way too nerdy now

 

[96NotOut]

In'Sha'Allah 75/75 (for me as well).

InShaaAllah.

Hiiiiiiiiiiiiii

Change your signature!!

Just had a cockroach crawl on my feet! Uuuuggggghh! Disgusting!

 

[Haz95]

Damn it!

what's the problem?

 

[96NotOut]

I just remembered this biology question - why do humans have a high and constant respiration rate, and why does the respiration rate of plants vary widely?

 

[96NotOut]

Honestly... I'd murder Haz, Ikball and even Afridi96 for this.

 

[Afridi96]

Oh kia hua?

 

[Afridi96]

Found a good way to revise, do a question then come on PP for 2/3 mins, then do a question.

 

[Haz95]

Looooool, for a second there I though you were 96* nice signature

Somebody please answer this.

I think I messed up.

 

[96NotOut]

You were the first to take it.

 

[HamzaSaeen]

Because plants respire at night mostly not during the day I believe

The respiration rate of plants is constant throughout the day, whereas it varies for humans because it depends on our activities and how much energy we need.

So your answer doesn't fit. :/

 

[HamzaSaeen]

No- don't plants photosynthesise during the day and respire at night? In the day they give out oxygen, in the night they take on oxygen for respiration.

 

[Afridi96]

Your answer contradicts the question :s

 

[96NotOut]

No- don't plants photosynthesise during the day and respire at night? In the day they give out oxygen, in the night they take on oxygen for respiration.

The photosynthesize during the day, but respire at night and during the day. The rate of photosynthesis overtakes the rate of respiration during the day, which is why they give out oxygen.

Do you have biology?

 

[HamzaSaeen]

My answer is correct- just verified it via Google and all sites say that plant respiration happens more during the night because during the day they're photosynthesisising.

 

[96NotOut]

Your answer contradicts the question :s

That's the problem.

I got that question in my CIE and this is the answer that I wrote.

The question makes no sense to me... Humans DON'T have a constant respiration rate.

 

[HamzaSaeen]

The photosynthesize during the day, but respire at night and during the day. The rate of photosynthesis overtakes the rate of respiration during the day, which is why they give out oxygen.

I had biology in O levels.
Rate of respiration overtakes rate of photosynthesis at night.

Did you check Student Room?

 

[96NotOut]

My answer is correct- just verified it via Google and most sites say that plant respiration happens more during the night because during the day they're photosynthesisising.

I never said you were wrong, but plants respire the same throughout the day... At least that's what all my books say.

The only thing that changes is the rate of photosynthesis, which affects the taking in and giving out of oxygen.

 

[Zohaib Shah]

So many biology experts in this thread. Looks like Pp has been raising some sciencetist.

 

[Zohaib Shah]

Its not nerdy till BL starts typing.

 

[96NotOut]

Answer that question and I will.

It was a 7 mark question, and I'm yet to find someone who knows the answer.

 

[blinding light]

I wanted to log in a while before, but all the physics talk gave me a headache ..

Please bacho, ab tou koi aur baat karlo..

Exactly!
At night more oxygen is taken in for respiration!

 

[96NotOut]

I had biology in O levels.
Rate of respiration overtakes rate of photosynthesis at night.

Yes, but ONLY because the rate of photosynthesis falls. The rate of respiration is still the same.

 

[96NotOut]

Did you check Student Room?

Nope... :/

 

[Zohaib Shah]

Speak of the devil...

Wow your here? I thought you were gone.

 

[Haz95]

Yes, but ONLY because the rate of photosynthesis falls. The rate of respiration is still the same.

I dunno whether its right or not but in humans, we need a constant environment-ion, water, sugar content due to homeostasis but in plants it varies..at times there's more Glucose levels than CO2 levels. As a result of this at certain points there will be less...
