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.

What are forms of cell regulation
Naddik [55]

Answer:

Hi!

Question :What are forms of cell regulation

Answer: Regulator Molecules of the Cell Cycle. In addition to the internally controlled checkpoints, there are two groups of intracellular molecules that regulate the cell cycle. These regulatory molecules either promote progress of the cell to the next phase (positive regulation) or halt the cycle (negative regulation).

Remember: Any process that controls the series of events by which a cell goes through the cell cycle. During the cell cycle, a cell makes a copy of its DNA and other contents, and divides in two.
