On Earth, the northern polar jet stream is the most important one for aviation and weather forecasting, as it is much stronger and at a much lower altitude than thesubtropical jet streams and also covers many countries in the Northern Hemisphere, while the southern polar jet stream mostly circles Antarctica

This sample is naturally occurring, inorganic, solid, has a square crystal structure, and a definite chemical composition (NaCl)

Alika [10]

Answer:

A Mineral is defined as an inorganic, naturally occurring, homogenoussolid, with a definite chemical composition, and ordered (crystalline) atomic structures.

Explanation:

Inorganic: Involving neither organic life nor the products created from or by organic life.

Naturally Occurring: Must be formed by natural processes, meaning a mineral cannot be manmade, manufactured, or created in a laboratory.

Homogeneous Solid: A mineral must be chemically and physically uniform down to the atomic level.

This homogeneity means that the mineral will have absolutely predictable physical properties

including hardness, density, and streak.

Definite Chemical Composition means that all occurrences of that mineral have a chemical

composition that varies within a specific limited range and the atoms that make up the mineral must

occur in specific ratios.

Ordered Atomic structure (Crystalline): The atoms in a mineral are arranged in a systematic and

repeating pattern. Glasses such as obsidian, which are disordered solids, liquids (e.g., water,

mercury), and gases (e.g., air) do not have a crystalline structure and are therefore not minerals.

Gause's experiments on two species of paramecium with very similar niches allowed him to formulate the principle of competitive

iren [92.7K]

The given example suggests the principle of resource partitioning.

The resource partitioning is a method of division of resources present in a particular niche to avoid the competition. In this case, the organism divide the regions having the abundant resources and they do not interfere in each others region.

In this case, the resource partition takes place by dividing the regions in the flask. one species use he resources present in the middle region and other uses the resource in the bottom.

Why does the kinetic energy change? Is it the mass or the speed that causes the change?

gogolik [260]

Answer:

Both speed and mass causes the kinetic energy to change.

Explanation:

The energy an object because of its motion is called as Kinetic energy. A object that moves be it horizontal or vertical direction possess kinetic energy. Some forms of kinetic energy are rotational, vibrational, translational. The kinetic energy(K) of the object depends on two components i.e., the mass (m) of the object involved and its speed(v)

The relation between the mass, speed of the object can be represented as

$\text{Kinetic energy}=\frac{1}{2}$ mass $\times$velocity$^{2}$$

Kinetic energy$=\frac{1}{2} m \times v^{2}$

Thus when there is a increase in the mass and speed, the kinetic energy will also increase
