Can the function f(t) = sint + cost  ,      represent SHM ?

 

Plz explain in detail.

when there will be only four letters in between P & S

 

then we can arrange P & S at this particular distance 14 times.

 

And for the remaining alphabets no. of permutations is (10! / 2!)

 

And thus total No. of permutations will be = (10! / 2! ) * 14

                                                            = 25401600

 

 

Cheers.......... 

I agree with u mukul ans is this only , but plz let me know what is back bonding ?

 

And how does it explians the stability of CF₃⁺

 

Thanks.........

Plz explain which is more stable

 

CF₃⁺                or                CF₃CH₂⁺

Hey ashish !

just see this

 

Concentration= Moles / Litre

 

Litre stands for volume(V), moles is no. of moles(n)

 

but n= Mass(m) / Molar mass(M)

 

 

therefore,

                   Concentration =  m/MV

 

but m/V is density (d)

 

so, Concentration is density / Molar mass

 

i could not get the logic why you used triangular numbers in the problem

1+2+2+3+3+3+4+4+4+4+..........

 

plz explain it in dtail quickly

at centre of mass, vector sum of mass momenta of all particles is zero, therefore if centre of mass is at origin, m₁r₁+m₂r₂=0. therefore r₁ = -m₂r₂/m1

which implies that if r₁ is negative r₂ is positive and vice-versa.
