THREE-DIMENSIONAL THINKING
ANEK [815]

The presence of potential energy  between particles supports the shape of a heating curve.

<h2>Potential energy and heating curve</h2>

The existence of potential energy  between particles supports the shape of a heating curve because potential energy causes the heating curve flat as well as in curve form. The heating curves show how the temperature changes as a substance is heated up.

The potential energy of the molecules will increase anytime energy is being supplied to the system but the temperature is not increasing so when the heating curve go flat it means there is potential energy so we can conclude that the existence of potential energy  between particles supports the shape of a heating curve.

The height of the upper falls at Yellowstone Falls is 33 m. When the water reaches the bottom of the falls, its speed is 26 m/s.
Klio2033 [76]

Answer:

Speed of water at the top of fall = 5.40 m/s

Explanation:

We have equation of motion

v^2=u^2+2as

Here final velocity, v = 26 m/s

a = acceleration due to gravity

a=9.8m/s^2 \\

displacement, s = 33 m

Substituting

26^2=u^2+2\times 9.8 \times 33\\\\u^2=29.2\\\\u=5.40m/s \\

Speed of water at the top of fall = 5.40 m/s

Explain why sugar was used in this experiment. How does the experiment relate to a baker adding yeast to bread to make it rise?
tia_tia [17]

Answer:

Yeast can use oxygen to release the energy from sugar (like you can) in the process called "respiration". ... So, the more sugar there is, the more active the yeast will be and the faster its growth (up to a certain point - even yeast cannot grow in very strong sugar - such as honey).
