if hybridization patterns of NH and SF gave sp3 and sp3d2 respecticely what is the value of 2 x + 3 y

The value of 2x+3y is 26

Explanation:

Because NH pattern gave hybridization Sp3

Just like NH3 Or NH2-

And SF pattern gave hybridization Sp3d2

Also just like SF6

X is the static no. of NH pattern

So X=4

Y is the static no. Of SF pattern

So Y = 6

Value of 2X+3Y

2*4 + 3*6

26

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
