Answer:
Because heat is a path function or the energy in transit.
Explanation:
- It is not correct to say that a body contains a certain amount of heat because the heat is a path function and not a property of the system. It is the energy in transit which can be encountered only when it crosses the system boundary.
- Heat is the energy in transit of a matter which flows by the virtue of temperature difference. The heat energy in a body is stored in the form of kinetic energy of the molecules which gets converted into heat that we know as the responsible factor for the rise in temperature usually.
To solve this problem we will apply the concept of voltage given by Coulomb's laws. From there we will define the charges and the distance, and we will obtain the total value of the potential difference in the system.
The length of diagonal is given as

The distance of the center of the square from each of the corners is

The potential electric at the center due to each cornet charge is




The total electric potential at the center of the given square is


Al the charges are equal, and the distance are equal to a, then


Therefore the correct option is E.
Radioactive decay is used to determine absolute age.

Answer:
The community may regress to the denial stage or stagnate in the fragmentation stage.
Explanation:
An habitat is a place where organisms live. It provides the basic essentials of living for the organisms. Examples are; terrestrial, aquatic etc. Fragmentation of an habitat can occur due to some natural or artificial processes.
Habitat fragmentation is the process in which a large area of habitat is transformed into a number of smaller areas. These smaller patches are segregated from each other.
This may cause the extinction of some species due to edge effect.
If actions taken during the fragmentation stage are partially successful, the community in the habitat may regress to the denial stage or stagnate in the fragmentation stage.
