The gravitational potential energy of Sara at the given height is 10594.8J.
Given the data in the question;
- Mass of Sara;
- Distance from ground;
- Acceleration due to gravity;
- Gravitational potential energy;
<h3>Gravitational Potential Energy</h3>
Gravitational potential energy is the potential energy an object with mass posessses relative to another object with mass due to gravity.
It is expressed as;
Where m is mass, h is height and g is acceleration due to gravity.
To determine the gravitational potential energy of Sara, we substitute our given values into the expression above.
Therefore, the gravitational potential energy of Sara at the given height is 10594.8J.

A. True
However, this is not necessarily the only factor that makes this true.
Answer:
confirm the results if you're using edge
Explanation:
Ok, particle is not a very nice word, no real sense of size associated with it
it can be a group of molecules like a speck of sand
referring to the molecules themselves
or refering to the atoms that make up the molecule
now in terms of phase change,
if we consider a speck- a group of molecules- then solids will expand when heated, however this definition falls flat in terms of phase change
ok, how about molecules, as molecules undergo phase change, the molecules in relation to each other will move apart from one another. Solid- molecules are bonded, Liquids- molecules are close and flow around each other, Gas- molecules are a significant distance from one another. But the increase in size when you heat up a molecule, i would have to say yes. adding heat increases energy which increases molecular vibration which would probably increase the overall average size to some unnoticeable degree.
now standalone atoms are just atoms, if you want to consider the electron cloud as size, then heating it up would negligibly cause the outer move outward. but it really depends on the scale of the question
