Hey what did u get for the current in cell x question and the escalator question

Don't remember can you tell me more about the question?

 

[Princess Raven]

Um

Don't remember can you tell me more about the question?

there were two cells x and y both had internal resistance and both were connected to a resistor of resistance 8 and the question was what is tje resistance in cell X I think the options were 0.1, 0.5,0.9 and 1 and the escalator one was about how much power Is needed to move 60 passengers of mass 40 I think up the escalator I don't know the options but I got 6.4

 

[Asad rehman]

the correct one was evaporation or condensation i went for condensation because the temperature was varying like for every 1 degree rise in temp molecules were gaining speed and likewise a fixed temp was also written there so boiling also was there.

that was 8.8KW+2KW due to friction and final answer was 10.8 and option D.

 

[Princess Raven]

Lol I got 4.4kw + 2kw which is 6.4kw

that was 8.8KW+2KW due to friction and final answer was 10.8 and option D.

 

[Snowysangel]

i remember 21-24 were C and the last three were aswell. the mcqs im kinda sure about

In the last 3 uses questions, I got 2 neutrons and 1 neutron in 2 of the questions

 

[Princess Raven]

Yea it's correct

 

[Snowysangel]

I did B i have no clue why

It was B..

 

[Asad rehman]

there was question in which ball is released in sphere in absence of air resistance at at lowest point speed was 4ms-1 and what is point at which energy of ball is one fourth of it?

Don't remember can you tell me more about the question?

 

[Princess Raven]

Yea

there was question in which ball is released in sphere in absence of air resistance at at lowest point speed was 4ms-1 and what is point at which energy of ball is one fourth of it?

that was C point S

B I think

 

[Snowysangel]

Bye doesn't a diffraction grating make the fringe sharper since there are more interferences

 

[Snowysangel]

Yea

that was C point S

There was no point S just A B C D

 

[Princess Raven]

There was no point S just A B C D

No there was point point p,q,s and something else option C was point S

 

[Kamihus]

that was 8.8KW+2KW due to friction and final answer was 10.8 and option D.

Lol I got 4.4kw + 2kw which is 6.4kw

I got 10.8 too but we had to multiply 8.8 by sin30 I guess so 6.4 is the right answer I think

I just guessed 0.9 for it

Haha I guessed 0.1 or 0.5 for it can't rmr though

Yup I did B but everyone here is saying its C

There was no point S just A B C D

No there was point point p,q,s and something else option C was point S

The last one was none of the above and I did A which no one did

 

[Snowysangel]

Yup I did B but everyone here is saying its C


The last one was none of the above and I did point Q which no one did

I might have marked q

 

[Snowysangel]

What about the question in which there were 5 resistors and 2 were parallel to 1...1 was right next to the battery and 1 was somewhere else...they asked us to write the resistances of the last resistor and the one parallel to the two resistors (one if which had a resistance of 1 ohm)...I guessed 3 ohms and 2 ohms. What did u guys write)
