If a child is swinging back and forth on a swing. Changes in her kinetic and potential energy are happening each moment .
<h3>What is mechanical energy?</h3>
The sum of all the energy in motion (total kinetic energy) and all the energy that is stored in the system (total potential energy) is known as mechanical energy .
As given in the problem a child is swinging back and forth on a swing. Changes in her kinetic and potential energy are happening each moment .
At the extreme end of the swing, the potential energy of the child is maximum and the at lowest height of the swing the kinetic energy of the child is maximum .

What I’m going to need more info about that
Answer:
four layers
Most rainforests are structured in four layers: emergent, canopy, understory, and forest floor.
Explanation:
Carbon dioxide (chemical formula CO2) is a colorless and odorless gas that is vital to life on Earth. This naturally occurring chemical compound is made up of a carbon atom contently double bonded to two oxygen atoms. Carbon dioxide exists in Earth's atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume.Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater. It is present in deposits of petroleum and natural gas.
