''Friction is a way to create electricity because it creates charged particles. ''

Answers

Friction actually generated friction because you create charges that are dealing with electricity. When you rub some against each other , you can create a little spark which is electricity . Friction can produce static or something because it can be transferred by two or more items .

On a hot summer day, air rises most quickly when it is above a desert. The correct option is C.

What is a desert?

A desert is a barren area of land with little precipitation and, as a result, hostile living conditions for plant and animal life.

The lack of vegetation exposes the ground's unprotected surface to denudation. Arid or semi-arid regions cover roughly one-third of the Earth's land surface.

Although the majority of deserts, such as the Sahara in North Africa and the deserts of the southwestern United States, Mexico, and Australia, occur at low latitudes.

Arid climates have less cloud cover than humid climates, and cloud tops reflect a significant amount of the sun's energy back into space, reducing surface heating. On a hot summer day, air rises the fastest above a desert.

Thus, the correct option is C.

Which correctly lists two characteristics of crystal faces that define crystal systems?

angle and number

size and hardness
size and angle

Answers

Answer:

A. - angle and number

Explanation:

(>-<)

The size of the crystal faces and the angle between them define the crystal system. Therefore, option (D) is correct.

What is a crystal system?

A crystal system indicates many classes of crystals, space groups, and lattices. In crystallography terms,  crystal system and lattice system are associated with each other. The crystals based on their point groups are divided into seven crystal systems.

The seven-crystal system is the Cubic, Tetragonal, Hexagonal, Orthorhombic, Monoclinic, Triclinic, and Rhomohedral systems. The classification of Seven Crystal Systems is depending upon their lattice and atomic structure.

The size and length of their surfaces which are known as ‘faces’ and sides, and the angles between them, define the shapes of crystals. The cubic crystal system is the most symmetrical as all the angles and the length of the edges is equal.

While the triclinic is the most unsymmetrical crystal system as all the lengths and the angles between faces are unequal.

How does hot object produce heat?

The hot objects create hot air producing heat.
Movement of the hot object creates heat.
Molecules in the hot objects create friction to produce heat energy.
Heat is absorbed the object from the air around it.

Answers

The object can creat heat from energy and friction but in some cases that’s not the case.
When objects are heated, the movement between the particles of the matter increases. As a result, particles move and vibrate more faster. When this happens, the heat can be transferred by vibrations between particles. Hope this is correct. If yes, please give me the brainliest

What is mineral ?

A mineral or mineral species is, generally speaking, a solid chemical compound that naturally occurs in pure form and has a very well-defined chemical composition as well as a particular crystal structure.

Each crystal structure that makes up a chemical compound that exists naturally as a separate mineral species. As an illustration, silicon dioxide is a component of the same mineral species as quartz and stishovite.

They can be mined and have the potential to be exploited as a source of metal. Manganese, iron ore, and bauxite are examples of metallic minerals, which can be either ferrous or non-ferrous. While ferrous minerals do contain iron, non-ferrous minerals do not.

Thus, option B is correct.
