i only realised this when my hamster's cage was infested with babies of these flies, i can see adults too.after i wash the cage, they appeared again after a few days. then i reaslied it was because of the hamster food that has FRUITS in it. and prolly my hamster didnt eat them.

you know too that when u put a banana in the living room after a whileyou see these flies.

where do you think they come from? it appears, from nowhere.

For oscillations: omega^2 x amplitude = acceleration, i thought it should be acceleration=-omega^2xdisplace...
Is displacement always equal to amplitude?
Where is the negative sign and when do we have to take into consideration the negative sign?

I totally cannot understand how the equations are used in the topic oscillations are used and i always fail with 0 marks cause i don't even know what formula to use, can someone please explain to me.

like i saw v=+/- (omega x square root of x0^2-x^2) what is x0?
and why i see another formula for velocity to be -x0sin(omega x t)
where t=time???

what is the difference between x0 and amplitude, i thought they are the same?

HELP, i can't understand and i am suffering from a mental breakdown at the moment.

Please reply fast!!!

Assume there is a 5-numbered lottery. Would the probability of winning the lottery be higher if you chose the numbers [1,2,3,4,5] or when you choose any 5 random numbers? You can back up your argument with mathematical calculations.

My intuition says that the 5 random numbers would be higher, whereas my reason says that they would be equal. Can someone explain this to me?

I'm near sighted, but when I squint my eyes or look through a small hole I see beter. Why is this? Would this be a way of improving eyesight or would the small field of view make it impractical?
