Biology; Chemistry; Physics: Post your doubts here!

Can someone tell me how to be really fast at doing mental calculations? :3

I mean, i'm fast. But like if someone asks me a question randomly 5860 x 250.. i am unable to do it in my head fast enough.
Does anyone know any ways to improve this speed? .-.

Biology doesn't have a P4.

ATP man
what else could it be?

break it down
5860 x 5 x 5 x 10

Most relevant thing somebody asked.

What did you get in bio in your mocks?

A*.

Biology doesn't have a P4.

if a car is moving to the right ...... so that means the tyre will be moving to the left whenthey touch the ground ......where will the frictional force be acting on the tyre

 

[funky brat]

Can't find it. Which variant? Which question? :/

variant 42 and question 2, I guess.

Towards the right. The tyres will be moving backwards when car move forwards so the friction opposes motion of the tyres.

 

[funky brat]

its easy
what is the problem?

I found it very confusing.

Guys question 2. That H thing. I've never seen such stigma before.

*Sigh*

Don't even know what stigma is.

About measuring the wavelength part bii, I think.

But isnt that one of a wind pollinated flower.I mean they always have feathery stigma that hangs out to catch the small pollen.Its an important and certainly recognizable part

91% I had a really easy paper.
I know the function but I would have never thought it would be a stigma.

My paper was really easy too.Hope that easy one comes in CIEs too...

very stupid question by CIE, sort of deliberately-student-failing-technique
only hope is since it has come it wont come again
