The answer to your question is "20kgx9.8m/s" because weight is the force an object is exerting on another object, and the formula used to calculate force is <em>Force = Mass * Acceleration</em>.
Answer:
Increases
Explanation:
The kinetic energy _____ (Increses)
as the roller coaster goes downhill
Answer:
Chemical energy
Explanation:
The energy held in the foods molecules a lunch pack is composed of is chemical energy.
They occur within food substances which originates from plants and animals as giant organic molecules.
- Since food is often derived from plants and animals.
- Plants produce their own food by producing macromolecules from simple inorganic substances in the environment.
- Animals takes up these food and build their own body through it.
- Plants and animal parts constitutes organic molecules in which chemical energy is duly stored.
- When the molecules are broken down, they released their chemical potential energy into heat energy.
<h2><u><em>Nuclear reactions are processes in which the nucleus of an atom is changed.</em></u></h2>
Cells store energy either as carbohydrates or lipids (fats and oils).
Carbohydrates provide for fast, short term energy. They are a key part of cellular respiration.
Lipids provide for long term energy storage because storing lipids is much more effective than storing carbs. One gram of lipid can store twice as much as one gram of carbs. So to access this energy storage, cells must conduct hydrolysis (inserting a hydrogen and a hydroxide group to split off the energy).
Hope this helps!
