What happens to a glass of pure fruit juice when water is added to it?

The number of moles of fruit juice increases.
The number of moles of fruit juice decreases.
The molarity of the juice increases.
The molarity of the juice decreases.

The molarity of the juice decreases.

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per kg of the solvent.

where,

n = moles of solute

= volume of solution in L

As volume of solution is inversely proportional to molarity, as water is added to juice, the volume of solution increases and thus the molarity decreases.

The moles remain fixed on adding water to juice.

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

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.
