What is the correct classification of a mixture in which both a solid and a liquid are visible? a homogeneous mixture and a solution a homogeneous mixture and a suspension a heterogeneous mixture and a solution a heterogeneous mixture and a suspension

Option (c) is the correct answer.

Explanation:

When two or more substances are mixed together then it results into the formation of a solution.

When two or more substances are mixed together in different composition then the solution formed is known as a heterogeneous solution.

For example, sand mixed in water is a heterogeneous solution. Here, sand is solid and water is liquid.

Whereas a solution in which solute particles distribute themselves evenly is known as a homogeneous solution. It forms a clear solution.

Thus, we can conclude that the correct classification of a mixture in which both a solid and a liquid are visible is a heterogeneous mixture and a solution.

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
