A newspaper article states that toilet flushes waste about 7 gallons of water per flush. Why is this information most likely to

be incorrect?
a. newspapers do not generally give reliable information
b. the information provided by newspapers does not have scientific basis
c. scientific investigation shows that low flush toilets use about 1.6 gallons of water per flush
d. it is not possible for newspaper journalists to measure the exact amount of water used by a toilet flush

<span>c. scientific investigation shows that low flush toilets use about 1.6 gallons of water per flush

This number contradicts the established knowledge regarding how much water is used in a flush. Not only that, it doesn't make logical sense. You can see the amount that gets flushed between the water in the bowl and the water in the tank. This amount is not close to 7 gallons, which is two gallons more than the water jugs on top of water coolers. </span>

Each of the four expansion models (recollapsing, critical, coasting, and accelerating) predict different ages for the universe,
cupoosta [38]

Answer:

This is because the age of the universe is determined by the pace of expansion in the past, and each model forecasts a different pace.

Explanation:

The age of the universe is determined by the pace of expansion in the past, and each model forecasts a different pace.

This is due to the fact that the expansion rate in the coasting model is constant and never changes. Because the cosmos is growing faster now than during the old days, recollapsing and critical models give shorter ages. According to the accelerating model, the universe is growing at a slower rate currently than in the past, implying an older age.

The energy stored by any pair of positive charges is inversely proportional to the distance between them, and directly proportio
denpristay [2]

Answer:

 U = 25 J

Explanation:

The energy in a set of charges is given by

          U = k \sum \frac{q_i}{r_i}

in this case we have three charges of equal magnitude

          q = q₁ = q₂ = q₃

with the configuration of an equilateral triangle all distances are worth

          d = a

          U = k ( \frac{q_1q_2}{ r_1_2 } + \frac{q_1q_3}{r_1_3} + \frac{q_2q_3}{r_2_3} )

we substitute

           15 = k q² (3 / a)

            k q² /a = 5

For the second configuration a load is moved to the measured point of the other two

          d₁₃ = a

The distance to charge 2 that is at the midpoint of the other two is

          d₁₂ = d₂₃ = a / 2

           U = k (\frac{q_1q_2}{ r_1_2 } + \frac{q_1q_3}{r_1_3} + \frac{q_2q_3}{r_2_3})

            U = k q² (  \frac{2}{a} + \frac{1}{a} + \frac{2}{a} )

            U = (kq² /a) 5

substituting

            U = 5 5

            U = 25 J
