HOW WAS PHYSICS PAPER 5 PPL ? HOW WAS YOUR EXAM ?

how'd u attach a weight to it?

using thread.etc..

 

[Rabib_69]

yes, but they wanted us to see how wind speed affects the angle of inclination right? do we need the effects of any mass here?

 

[kirashinagami]

no.. i attached a weight to balloon.. it was stated that a small helium balloon is provided...

Why weight? Ofcourse it will fall to the ground

 

[ishraqul]

did u guys give 51 52 or 53?

load kept on a table . duuhhh

 

[ousamah112]

how the hell did you measure wind speed ? what instrument ? and wat did u use to vary wind speed

i used fan.. and speed of fan was the speed of wind... i couldnt think of anything else..:s

 

[mr_perfect]

did u guys give 51 52 or 53?

hey kid aint u from scholastica batch of 2012 ???

 

[ishraqul]

so u need to vary wind speed and measure angle? how do u vary the wind speed? how do u measure the speed?

 

[kirashinagami]

Just use a nail . If used mass, the rope may slip through

in our home fans when we set the speed to 3 does that mean wind speed is 3 m/s ????

 

[kirashinagami]

so u need to vary wind speed and measure angle? how do u vary the wind speed? how do u measure the speed?

I used 23th century fan

in our home fans when we set the speed to 3 does that mean wind speed is 3 m/s ????

Ofcourse no

 

[Rabib_69]

ohh u could just tape it to the ground

 

[earthling]

Anemometer is an instrument used to measure wind speed. Idk abt "inside" the laboratory tho.

how'd u measure the speed? I just said varied it :|

Is it even in our syllabus?

 

[mr_perfect]

Just use a nail . If used mass, the rope may slip through

but wat if i tie down the rope to the mass . u know like they wrap around gift packs. that same way

 

[kirashinagami]

how'd u measure the speed? I just said varied it :|

I connected voltmeter and ammeter to the fan.

Ohh if you said that, i think its ok

And measured what? The resistance?
