1 answer:

4 0

Definition. According to Newton's law of universal gravitation, the attractive force (F) between two point-like bodies is directly proportional to the product of their masses (m1 andm2), and inversely proportional to the square of the distance, r, (inverse-square law) between them: ... κ = 8πc4G ≈ 2.071×10−43 s2⋅m−1⋅kg−1.

Which of the following items is NOT one of the five criteria listed for the strict definition of a MINERAL? Crystalline structur

Gala2k [10]

Answer:

Texture is not one of the five criteria listed for the strict definition of a mineral.

Explanation:

A mineral is generally defined as a naturally occurring solid chemical compound which is present in its pure from. A substance is said to be a mineral, if it satisfies the following five criteria: naturally occurring, solid, inorganic, ordered internal structure, definite chemical composition.

Therefore, a mineral is a naturally occurring solid inorganic substance with a well-defined chemical composition and specific crystalline structure.

Therefore, we can say that texture is not one of the criteria that defines a mineral.

fgiga [73]

A sand sample consisting of minerals deposited by water is hydrogenous.

<h3>What is hydrogenous sand?</h3>

This are sand that are from water Bodies.

The sands form during evaporation as a result of samples that settles in Water.

This sand are abundance in sea and water bodies.

Therefore, A sand sample consisting of minerals deposited by water is hydrogenous.

Study the image

eimsori [14]

Answer:

This question is incomplete, because there is no picture, but I attached one, related with the question. The correct answer Trade winds are shown as number 1.

Explanation:

Trade winds and permamnet winds which blow between Tropic of Cancer, Equator and Tropic of Capricorn (which is between 30 degrees N and 30 degrees S.

These wind always flows from Tropics towards the Eqautor, because around the Eqautor is permanent low pressure area, and around the Tropics is permanent high pressure area. Air always flows from high pressure towards low pressure area.

Due to Earth's rotation trade winds curve a little bit, a they become prevailing Northeasterly Trades (in Northern hemisphere) and Southeasterly Trades (in Southern hemisphere). Earth rotates in west-east direction, and that is the reason for their deflection.

Trade winds got their name in the Age of Discovery (14-15 century) when sailing around the world and explorations were very common. Explorers find out that in specific regions exist winds with permanent direction. That was very importnant in the Middle Ages, so explorers always followed their patterns. Term 'trade' is actually from Middle English and it means 'track'.
