Answer:

Hi there!

Your answer is D. Halfway up the peak

Explanation:

Think of potential energy like you are a marble. If a marble is at the peak of the hill, it's potential energy is ENORMOUS because as gravity pulls it downward it will increase in speed. Halfways down the peak is about the same potential energy as the peak, although slightly less. At the end of the climb, we can assume the landscape flattens out. This means there's very little pull to make it change at all. It will continue with the speed gained from the downhill trajectory until something in its environment stops it (such as friction). When a marble is at the bottom of a large hill, the potential energy is low. It takes a lot of force to try and get up the hill, losing lots of energy

I hope this makes sense!

Explanation:

Gravitational potential energy = mgh, where m is the mass of the mountain climber, g is the gravitational force and h is the height from the base.

Since m and g are constants, the climber's potential energy will be the lowest when he's at the end of the climb, at the base of the mountain. (B)

Why does a hot air balloon rise?
alina1380 [7]

Answer: Hot air is less dense than cool air; the heated air causes the balloon to rise simply because it is lighter than an equal volume of cold air. Buoyancy is an upward force that the air exerts, and it helps hot-air balloons and blimps stay in the air. A hot air balloon uses a burner to heat up the air inside the balloon.

Hope this helps!!! Good luck!!! ;)

<h2><em><u>Answer:</u></em></h2>

The five steps that are always taken in scientific research are;

  • Recognizing the problem
  • establishing a hypothesis
  • doing research and assembling data
  • escorting the experiment
  • and finally proceeding to a conclusion
<h2><em><u>Explanation:</u></em></h2>
  • Arya already performs the first two steps; as she first recognize the problem i.e. she observes the dry glass and she also formulate a hypothesis that "the water content in the soil is about two-thirds lower than that of other yards in the area"

  • Now she will collect the data and conduct the experiment on the soil and glass and then she will assemble the conclusion based on the results.Now she will collect the data and conduct the experiment on the soil and glass and then she will assemble the conclusion based on the results.
