5. Which state(s) of matter |s/ar epsilon easily compressible? Select all that apply. -liquid
-solid
-gas
-none

Gas

Explanation:

The atoms, ions, or molecules that make up the gas are further apart and move freely at high speeds and is can easily be compressible.

Gas

Explanation:

A gas is a substance or matter in a state in which it will expand freely to fill the whole of a container' having no shape like a solid and no fixed volume like a liquid.

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

it's all four options.
