Describe, in your words, and using examples, what is meant by the term solubility

Well, really, it says in your words, so you should really be answering this on your own, but see below for what my answer would be.

Explanation:

Solubility is the ability of something to be dissolved, especially in water. Something with high solubility, such as salt, easily and quickly dissolves in a glass of water, and something with low solubility, such as oil, will take a long time to dissolve in water, or as in the case of oil, it may not dissolve at all.

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
