R + R e

S_x = u_x t
after one collision velocity becomes eu

answer is B but how

2 iodides of mercury are Hg₂I₂ and HgI₂. one of them appears red and other one green. then

a) the d- orbital splitting is stronger in Hg_2²⁺ than Hg²⁺ ion

b) Hg₂I₂ red photons from light

c) HgI₂ absorbs red photons from light

d) None

is d the answer

acids r electron acceptors when Mn is in +5 state it has more affinity for electrons that is why it is more acidic rate me

both r having 2 acidic hydrogens put due to presence of 2 P=O groups in H3PO4 it becomes more polar and acidic

delta T_f = i K_f X m

m = 0.5 X 10 / 74.5

get i and use 1 + x = i

x = degree of dissociation

rate me

the current (10/3 A )will definitely flow from B to A

Q1 put sin@ = (2tan @/2) / 1 + tan² @/2

and cos @ = (1- tan² @/2 ) / ( 1 + tan² @/2 )

A PERSON WANTS TO DRIVE A NAIL OF MASS 'm' INTO THE WALL OF DEPTH 'H' FOR THIS HE HITS WITH A MASS 'M' FROM A DISTANCE 'R' REPEATEDLY. THE OPPOSITION TO THE PENETRATION OF NAIL WILL BE

a heavy disc is gently placed on a horizontal surface after it has been given angular velocity (v₀/r) IT WILL START ROLLING WITHOUT SLIPPING WHEN THE SPEED OF ITS CENTRE REDUCES TO

_{[ 0]}

^{[ 1]} e^x2(x - d) dx = 0

then find the range of values of 'd'

the given equation can be written as
y-x y' = 3-3x²y'

dy / y-3 = dx / x-3x²

A PERSON WANTS TO DRIVE A NAIL OF MASS 'm' INTO THE WALL OF DEPTH 'H' FOR THIS HE HITS WITH A MASS 'M' FROM A DISTANCE 'R' REPEATEDLY. THE OPPOSITION TO THE PENETRATION OF NAIL WILL BE

= n tan

then maximum value of tan²(
