@rkshtsurana said:@rachit_28@ayushnasaA solid figure has 6 faces that are squares and 8 faces that are equilateral triangles. Each of 24 edges are of 2 cm. Find the volume of the solid ?
{40rt(2)}/3?? Imagine karna hard tha :P

bhai mere to ans 8(rt2+3)/3 aa raha hai...

66 - 84 + 6
-12

so jao ab jake..SB se bhgya tha aapko 
yaha se bhag jao ab...
yaha se bhag jao ab...@Anivesh90 said:make combinations..
bhai combinations ka question hai, to combinations hi banege ! All he wants to know the combinations !
P.S: No offence intended.
@ayushnasa said:Kuch aisa sa figure bana...Sorry par yaah banana hard hai paint par..
hmm.. aage ka bhi batao..
@Anivesh90 said:hmm.. aage ka bhi batao..
Age ka?? 4 pyramid bante hai with base 2*2rt(2) and height 1. And ek cuboid banta hai with dimensions 2*2*2rt(2)..Bas solve kar ke add kia...
Good nyt then..Sab bhaga rahe hai aj

none taken.. but type krne ka man ni kr rha.. :P

assume 12345 as the pots..
first fix 1 in first position and try the arrangements youll get 2 combinations-->
13524 & 14253
similarly
fix 2=3 combinations
fix 3=4 combinations
fix 4=3 combinations
fix 5= 2 combinations
2. An atom A forms an ionic bond with an atom B by complete transfer of one electron to B. If internuclear distance is 2.67 × 10–10 m and charge on electron is 1.602 × 10–19 C, the dipole moment of the bond is
(1) 4.277 × 10–29 cm (2) 3.09 × 10–30 cm
(3) 1.96 × 10–30 cm (4) 4.56 × 10–28 cm
(1) 4.277 × 10–29 cm (2) 3.09 × 10–30 cm

option 1
D.M = internuclear dist x magnitude of chrge
