The table shows the range of the amount of energy required to break the bonds between the molecules of a substance in the solid, liquid, and gaseous states.
bond-breaking energy
state energy
p 3 units
q 0.01 unit
r 0.1 unit
which of the following is the correct order of the relative strengths of the intermolecular forces in the three states?
a. p > r > q
b. q > r > p
c. r > q > p
d. p > q > r

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

idk what the question is about
