Answer:
A potential
B kinetic
Explanation:
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
Where, K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Potential energy can be defined as an energy possessed by an object or body due to its position.
Mathematically, potential energy is given by the formula;
Where, P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
Both potential and kinetic energy is affected by an object's mass.
Option A is the right one for this question.
The undergrowth of tropical rainforest most likely requires less sunlight.
The tropical rainforest floor receives only 2% of the sunlight; only plants can grow in this region.
The forest floor is a relatively clear of vegetarian, because of the low sunlight penetration.
Answer:
Radiometric dating for the analysis of isotopes in the fossil.
Explanation:
Radiometric dating can be used to determine the precise age of a fossil by measuring isotoped decay within tge fossil or the surrounding rock in contact with it.
For food... because the eat worms and seeds and other things
Answer: False.
Explanation:
Thermodynamics describes the states of thermodynamic equilibrium at the macroscopic level. <u>The states of equilibrium are studied and defined by means of extensive magnitudes such as internal energy, entropy, volume or molar composition of the system</u>, or by means of non-extensive magnitudes derived from the previous ones such as <u>temperature, pressure and chemical potential</u>.
Thermodynamics deals with the processes of heat transfer, which is one of the forms of energy and how one can work with it. This area describes how matter in any of its phases (solid, liquid, gas) is transformed. So from a macroscopic point of view of matter, it studies how it reacts to changes in its volume, pressure and temperature, among other magnitudes. Thermodynamics is based on four main laws:
- Thermodynamic equilibrium (or zero law)
- The principle of conservation of energy (first law)
- The temporary increase of entropy (second law)
- The impossibility of absolute zero (third law).
<u>In thermodynamics, a system is said to be in a state of thermodynamic equilibrium if it is incapable of spontaneously experiencing any change of state or thermodynamic process when it is subjected to certain boundary conditions</u> (the conditions imposed by its surroundings). For this purpose, it must be simultaneously in thermal equilibrium, mechanical equilibrium and chemical equilibrium.
Entropy (symbolized as S) is a physical magnitude for a thermodynamic system in equilibrium. It measures the number of micro states compatible with the macro state of equilibrium,<u> it can also be said that it measures the degree of organization of the system,</u> or that it is the reason for an increase in internal energy versus an increase in temperature of the thermodynamic system.
Entropy, in an isolated system, grows in the course of a naturally occurring process. A consequence of the second law of thermodynamics is that in a state of equilibrium, entropy has a maximum value in the system that will correspond to a minimum in one of the thermodynamic potentials.
