are you FRICKIN DAMN SURE ?

are you FRICKIN DAMN SURE ?
it is series...i bet...lets ask others about this. cuz im not quite sure myself
guys, are these 2 resistors connected in series or parallel ??
View attachment 10887
i got 12.8exactly 12.8 W !!
which one was 384?my answers were:
second last = 380 something something
last = 12.8
well then, im again back to losing 3 marks onlyit is series...i bet...
the part before it, the second last parti got 12.8
which one was 384?
wait i cant remembr, if it was my answer...bt is it pretty obvieous or tricky?the part before it, the second last part
P = IV
ring any bells ?
obvious.wait i cant remembr, if it was my answer...bt is it pretty obvieous or tricky?
can u tell ans of how temp remain constant when liquid changes to solid and what was melting point we have to tellobvious.
i am also sure they were series !! btw u got the right answers than hw you loose marks ?well then, im again back to losing 3 marks only
Theres a reason for it being downwards. That was a stationary point, and exactly after it the wave goes downward. Since each point of the wave is position of the particle, the arrow was to be down. Had it been upwards, the particle would've gone further up AFTER it.oh ok. but most ppl did it upwards.
Ok, help me here :
Q1) Mass, extension one.
Q2) Car's acceleration and stuff
Q3) House heating
Q4) angle of incidence and 32. something as angle of refraction one
Q5) wave motion and stuff
.
.
Q8) Wire and stuff
Q9) transformer wala
Q10) Gamme rays and Beta rays and stuff
What were question 6 and 7 about ?!?!?
moving to sec.BAny1 ????
look the pressure one was confusing to most people but u had to apply practicaly alll the pressure concepts here.The moment of force ka answser was A . using one anti clockwise = 2 clock wise
Table tennsie one was increase and decrease
bike one was A .
I still have my queries for that mcq the pressure volume one . The reason is most of the people used the formula pv=pv to attempt the question . This formula is applied when the container is some how decreasing in volume *Like a syringe * . As the containers were fixed .. one side had 200 cm3 of air .. the other had vacuum and a capacity of 100cm3 . When the valve opens .. firstly simple diffusion takes place ... causing air molecules to move from container A to B . Due to lessening of air molecules , the pressure decreases ... as the kinectic theory applies , the fewer the molecules the less chance of them striking the walls and hence less pressure . As its simple diffusion taking place and there is a movement of 100cm3 ... in container A only 100 cm3 is left , which is half the original . hence p/2 .
Those who can follow what i just wrote , please do see and some how prove that air molecules dont go from A to B but from B to A , cause thats the only way the answer could have been 2/3p
the total volume increses from 200 to 300. so pressure decreses from P to 2P/3How was it 2/3P? o.o
thanks ^__^ i did a lot of thinking at that question bcuz thre of us friends discussed it and everyone had ticked out a different option.. glad that mine was ryt!!yea agrees now daredevil a perfect explaination dude !!
