see the resonating structures.
there are two H-F bonds of bond order 1/2.

yup.. but thts how theories are born.. first assumptions and then solid proof.. neway leave this lol... hamein un scientists ke samne kuch bhi nahin aata

best answer would be
Let the 2 perpendicular lines be X axis and Y axis
thus eqn will be
| x | + | y | = 2 ...(distance from x axis = x coordinate, and from y axis = y coordinate)
put values of x and y as 2, 1 , 0 and see the points of intersection with x and y axes
locus is a tilted square with coordinates as (2,0) , (0,2)
, (-2,0) and (0, -2)

product of roots
a^3 = 1
therefore a = 1, w, w^2
also we know that 1 + w + w^2 = 0
sum of roots
a^2 + a = -p/3
substitute a^2 by 1/ a ( as acube = 1) and we get
(1+ a^2 ) / a = - p/3
as p>0
left hand side can only be -ve when a = w out of 1 , w and w^2
thus
a^2 + a = - p/3
==>> w^2 + w = -p/3
- 1 = -p/3 .. (as w^2 + w + 1 = 0)
p = 3

can u provide a diagram? and is the triangle equilateral or not mentioned. and is point O lying on the triangle? or inside or outside?

yes, 3 variables x, y and z and we have three equations for the three planes too..
3 equations 3 variables.. can be solved.

refer a friend to this site or post articles on community shelf

in black holes anti matter and matter come into same phase and matter stops existing in the form as we know it. ive read this in stephen hawking's works
|
|
|
|
|
lol do u know what anti matter is? it is a concept that for every matter there is anti matter.. u cant just take anti matter from something and work on it.

no hes perfectly correct.
acceleration of the car behaves in the same way as if car was stationary and acceleration was provided to the bob of pendulum in opp. direction. this is using concept of pseudoforce.
so let tension of tilted string making angle @ with vertical = T
equating forces on bob, we get
Tcos@ = mg
Tsin@ = ma
divide to solve and we get
tan@ = a / g. substitute values
tan@ = 2/ 9.8
@ = tan inverse (0.204) approx.

acceleration g does not depend on mass of the body when theyre neglibile compared to mass of earth.
thus if they reach ground at same time, the height from which theyre dropped is same. so ratio is 1:1.
s = ut + 1/2 a t^2
acceleration is independent of mass. it is force which depends on mass.

HERES TO CLARIFYING UR DOUBT OF GOING INTO THE FUTURE.
m = M / ( 1 - vsq/ c sq)^ (1/2)
u cant travel faster than light, as else there will be negative value under root sign hence equation will not be valid. at speed of light mass will become infinity.
but somehow if u were able to surpass speed of light...
u would jus be able to travel along with light and reach an area where light is going to reach soon. thus u can say uve seen the past of tht region. because for people in normal conditions , the place will be lighted already when they see it. but you went and saw it before light reached it cos ur faster than speed of light.
you cant go into the future. explain ur ideas and i will respond
