Select the correct answer. which sentence describes an object that has kinetic energy? a. a seagull sits on top of a fence post.
ololo11 [35]

" a boat sails across the ocean" possess Kinetic energy. hence option d is correct.

<h3>What is Kinetic energy?</h3>
  • Chemical energy, thermal energy, electromagnetic radiation, gravitational energy, electric energy, elastic energy, nuclear energy, and rest energy are only a few of the many different types of energy that exist. Potential energy and kinetic energy are the two basic categories that can be used to group them.
  • An object's kinetic energy is what drives its motion. Kinetic energy can be converted into other types of energy and transported between objects.
  • The energy an object has as a result of motion is known as kinetic energy in physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity. The body holds onto the kinetic energy it acquired during its acceleration until its speed changes.

What percentage of the total energy consumed was converted to forms that were unusable to become new growth for the chipmunk?
mrs_skeptik [129]

The percentage of energy that is unusable is obtained as 96.1 %.

<h3>What is the percentage of unusable to become new growth for the chipmunk?</h3>

We know from the law of conservation of energy that energy is neither created nor destroyed in the ecosystem but is converted from one form to another. We know that the ecosystem is a self supporting system in which there is an exchange of materials and energy. Energy flows from the producers to the consumers and some of this energy is dissipated along the way and is lost as heat during the transition.

The metabolic activities of an organism takes up some part of the energy that it receives from the sun.

From the question, we know that the energy consumed is 1000 J and the energy that is lost to waste and to respiration is 177 J and 784 J respectively. This implies that the available energy is 39J.

The percent of energy that is usable is;  39 J/100J * 100/1 = 3.9 %

The percent of energy that is unusable is; 961 J/1000 J × 100 % = 96.1 %
