The gravitational potential energy of Sara at the given height is 10594.8J.

Given the data in the question;

  • Mass of Sara; m; = 60kg
  • Distance from ground; h = 18m
  • Acceleration due to gravity; g = 9.81m/s^2
  • Gravitational potential energy; U = \ ?

<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;

U = mgh

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.

U = mgh\\\\U = 60kg * 9.81m/s^2 * 18m\\\\U = 10594.8kgm^2/s^2\\\\U = 10594.8J

Therefore, the gravitational potential energy of Sara at the given height is 10594.8J.

Identify the stage of mitosis where the chromatids line up on the equator of the cell
jok3333 [9.3K]
The stages of mitosis are:
1. Prophase
2. Metaphase
3. Anaphase
4. Telophase<span>

Prophase
This is when the </span><span>centrioles separate and move to opposing sides of the cell.

Metaphase
This is when the chromosomes line up in the center of the cell and become connected.

Anaphase
This is when the</span><span> "sister" chromatids separate into individual chromosomes and are pulled apart.

Telophase
This is the last phase of mitosis, when chromosomes gather at opposite ends of the cell and new nuclear membranes form.

The answer is metaphase, because that is when the chromatids line up in the center of the cell.

Answer:
Metaphase</span>
