What was the answer to that Earthing sphere mcq? A right?

 

[Mahnoorfatima]

How many points of the summary do we need to write? I mean out of 5 marks how much is for the content points? Approximately how many points do we have to note down?

 

[asadalam]

What was the answer to that Earthing sphere mcq? A right?

I think so,charge would be negative and the negative charge would flow into the sphere

 

[What is life]

What do you guys say, should i revise the syllabus once or get on with the past papers? For chemistry that is, cuz we dont have much time..

 

[Abdul Hanan]

Which year?

O/N 13 Both regions

Jin logon ka P2 acha howa aur apne answers bata k dosron se expected marks puch rahain hain ... to beta.... Allah puchay ga. ._.

Lol, I'm sorry.

Postive charge can't move so yeah.

 

[funky brat]

What was the pressure graph? With the increasing gradient or the one with a constant gradient?

 

[Awesome12]

What was the pressure graph? With the increasing gradient or the one with a constant gradient?

Option B

 

[funky brat]

Option B

Woh konsa tha? .-.

 

[Fate0]

Woh konsa tha? .-.

constant wala.

Whuuut which one is this?

 

[sameersuleman]

Q1. How was the distance 15.6??
Q2. Pressure in 2a was 333333.33 right?
Q3. There were four consecutive "c" answers in the last 7-8 MCQs right?

15.6 yes, i got the same.
I got 33.3 Why so much?
Umm I don't remember Last one was a C tho.

Pressure is taken in metre square so c.metre square was divided by 10000 .... I think... but how did 15.6 come because I got a different answer..

 

[Mazin Junaid]

Can someone quote me the exact question of the water heat capacity wala in which we had to find its mass? Cause I don't know why you had to multiply it by 8

Area under graph.
Triangle + Rectangle.
1
- x 3 x 2.4 + 5 + 2.4
2

The answer was 33.33 for N/cm and and was something big in 3's for the N/m one/

There were four consecutive "a" answers as well as four consecutive "c" answers,

 

[Mazin Junaid]

You had to calculate the area under the graph for the first 8 sec

 

[Laibaaa]

Can someone tell me the mcq for that 'Constant but not zero' from the graph?

The water in Pan A is cooled for 8 minutes. It loses 9000 heat energy per minute, something like that.
