Taxonomists have noted that as the number of organisms decreases, the more likely the organisms are to share similar characteristics.

Explanation:

A taxonomist is a biologist that groups organisms into categories.
A plant taxonomist for example, might study the origins and relationships between different types of roses while an insect taxonomist might focus on the relationships between different types of beetles.
Taxonomy is the process of naming and classifying things such as animals and plants into groups within a larger system, according to their similarities and differences.
Taxonomy entails the description, naming, and classification of living things.
It helps us categorize organisms so we can more easily communicate biological information. Taxonomy uses hierarchical classification as a way to help scientists understand and organize the diversity of life on our planet.
A taxonomic characteristic may be defined as any expressed attribute of an organism that can be evaluated and that has two or more discontinuous states or conditions.

What are the main forms of energy? Define each type

Fed [463]

Thermal energy - the internal kinetic energy in a substance caused by vibration of atoms and molecules. Thermal energy is also known as heat.

Radiant energy - is the electromagnetic energy that travels in waves. Radiant energy is kinetic energy that includes light, x-rays, microwaves, and radio waves.

Elastic energy - potential energy produced from stored or released elastic materials. This is stored mechanical energy energy resulting from being stretched or compressed.

Mechanical energy - the energy an object possesses due to movement. Mechanical energy is kinetic energy because it is the movement from one position to another.

Gravitational energy - the potential energy an object has because of position. This is produced from gravitational force acting upon an object.

Chemical energy - the potential energy stored in the bonds of molecules and compounds.

Nuclear energy - potential energy stored in the core (nucleus) of an atom.

Electrical energy - the kinetic energy produced from the movement of an electric charge.

In a given lightning flash, the potential difference between a cloud and the ground is 2.86 times 109 V and the quantity of char

Nadya [2.5K]

Answer:

Explanation:

decrease in energy of the transferred charge

= Voltage x charge

= 2.86 x 10⁹ x 23.1

= 66.067 x 10⁹ J

the final speed of the automobile be V

1/2 m v² = 66.067 x 10⁹

v² = 66.067 x 10⁹ x 2 / 1519

= .08698 x10⁹

= 87 x 10⁶

v = 9.32 x 10³ m / s

We often see cracks on rocks and stones why

Paul [167]

Answer:

Due to the process of weathering and erosion.

Explanation:

As the rocks are made of different forms of minerals they may have an igneous, metamorphic or sedimentary origin. Hence the natural stone surfaces can be made of granite, lime, or even shale.

The process of physical weathering that is called as mechanical weathering of rocks tends to break them apart and leads to the development of crack and small openings.

The diurnal exposure of bare rocks to extreme temperatures of day and night leads to onion peeling and slowly with water as an agent of erosion lead to cracks in joints of rocks.

In a collision between an electron and a hydrogen atom, it is useful to select both objects as the system because which of these

lukranit [14]

Answer:

Explanation:

Because of the following ,it is useful to select both objects as the system during collision between an electron and a hydrogen atom

1. The total momentum of the system does not change during the collision.

2.The forces the objects exert on each other are internal to the system and don't change the total momentum of the system.

3. During the time interval just before to just after the collision, external forces are negligible.

What is the difference between heat capacity and specific heat capacity? I want the meaning please.

charle [14.2K]

Answer:

The heat capacity of a body is defined as the heat required to raise it's temperature by me degree or one kelvin.while specific heat capacity of a substance is defined as the heat required to the temperature of a unit mass of it through one degree or one kelvin.

I hope it helps
