I am only confused about the answer to the MCQ about the diver. I did GPE to KE to Heat energy.

pressure remains unchanged vol increases

but pressure will increase as volume increases, wont it?

 

[danial 234]

but pressure will increase as volume increases, wont it?

pressure decreases as vol increases but heat was supplied which increased temp, this temp increased pressure. so overall there was no change

 

[Zuhsid]

Ans to that piston MCQ, pressure decreases n volum increases, ryt?

Yup

 

[Zuhsid]

So now.... the answer to the phy MCQ as to what happens to the voltmeter and ammeter readings if the filament in lamp 1 broke..... is that..... Ammeter reading decreases and voltmeter reading increases.... those of you who did it wrong...... Join the club!!

can u plz give answers to my question i wrote it with much difficulty i one post

Cant remember most of it r all these from p1?

ammeter increases voltmeter decreases

Both readings decreased

ammeter increases voltmeter decreases

No dude, filament vil break the circuit if it melts, so both readings decrease

 

[Zuhsid]

ammeter increases voltmeter decreases

Both readings decreased

Damn sure guys..... search it online if u dont believe me....!!

It works like this..... as re circuit broke... but the voltmeter was connected in its place..... so the potential difference around it would be maximum.... as one of its side was connected to the battery, directly....

Can u like direct me to the part where i could get my answer, coz the article is pretty big!!

see the first circuit and the third, it proves that you are right...

 

[Zuhsid]

Yea.... Most of the people did it wrong... including me!!

 

[areela hassan]

no i

Was 'high point' mentiomed?

t wasnt

 

[altox876]

no i
t wasnt

It was mentioned that he dove from a large height

Wouldn't a broken filament effectively break the circuit causing both readings to decrease?

just remembered this much! now answers plz

1) which graph?
2) dont remeber, i think A
3)added both 10000 n 5000 to calculate G.P.E
4) current same in series, voltage same in parallel
5) not sure, chose pressure decreases, vol increases
6) A
7) A
8) S-N N-S
9) Iron
10) 24 mins
11) Nucleus is small
12) --
13) Fuse blows
14) Virtual,not inverted
15) chose K.E + G.P > thermal
16)towards center
17) both same
18)A
19) C
20) --
21)Polyethene with woolen cloth
22) --
23) i think it came to be 3 x 10^3
24) chose both decrease
25) D
26) Frequency decreases
27) D
Guys correct me if i m wrong

Thats xactly my ques
