How gold is extracted?

User Avatar

Asked by Wiki User

Gold is typically extracted through mining, where ore containing gold is dug from the ground and crushed to extract the gold. This can be done through processes such as cyanidation, where a cyanide solution is mixed with the crushed ore to dissolve the gold, which is then separated and purified. Another method is called gold panning, where gold is separated from sediments through agitation in a pan.

Geologists determine the absolute age of rocks using?

User Avatar

Asked by Wiki User

Geologists determine the absolute age of rocks using radiometric dating techniques, such as carbon dating or uranium-lead dating. These methods rely on measuring the proportions of radioactive isotopes and their decay products in the rocks to calculate how long ago they formed.

What properties of waves affect the pitch and loudness of sound?

User Avatar

Asked by Wiki User

The frequency of a wave affects the pitch of sound, with higher frequencies producing higher pitched sounds. The amplitude of a wave affects the loudness of sound, with greater amplitudes producing louder sounds.

Suppose that you measure the intensity of radiation from carbon-14 in an ancient piece of wood to be 6 percent of what it would be in a freshly cut piece of wood How old is this artifact?

User Avatar

Asked by Wiki User

Based on the half-life of carbon-14 (about 5730 years), if the intensity of radiation from carbon-14 in the ancient wood is 6 percent of that in a fresh piece, the wood is approximately 3 half-lives old (5730 years x 3 = 17,190 years). Therefore, the artifact is roughly 17,190 years old.

Name the 4 main atmospheric factors that influence weather?

User Avatar

Asked by Wiki User

The four main atmospheric factors that influence weather are temperature, humidity, air pressure, and wind. These factors interact to determine the type of weather experienced in a particular region.

Does the size of the vibration affect the loudness of the sound?

User Avatar

Asked by Wiki User

Yes, the size of the vibration does affect the loudness of the sound. Generally, the larger the vibration, the louder the sound. This is because larger vibrations produce greater amplitudes in the sound wave, resulting in a more intense and louder sound.

Additional information needed for carbon dating?

User Avatar

Asked by Wiki User

To perform carbon dating, we need a sample that contains organic material that was once alive, such as wood, bone, or charcoal. The sample must be carefully collected and preserved to avoid contamination. We also need to know the approximate age of the sample to determine the appropriate method and laboratory to use for analysis.

8. What are the universals in phonological component?

User Avatar

Asked by Wiki User

Some universals in the phonological component of language include the use of distinct speech sounds (phonemes) to convey meaning, the presence of phonological rules that govern the permissible combinations of phonemes, and the existence of syllable structure constraints. These universals help define the underlying structure and organization of sounds in language.

Why is the toddler period called the prime time or critical time for learning language?

User Avatar

Asked by Wiki User

The toddler period has been called as the most critical time for learning language because most of a child's language development takes place at that time. They are off and exploring their world, but they are also putting words together to understand that world and linking the words together to carry on understandable conversations.

What is the scientific name of power?

Asked by Wiki User

Power does not have a scientific name as it is a abstract concept related to the ability to influence or control people or events.

What is the scientific name of pressure?

User Avatar

Asked by Wiki User

Pressure does not have a scientific name as it is a physical quantity that measures force per unit area. In the SI system, pressure is measured in pascals (Pa).

What are the examples of the law of apperception?

User Avatar

Asked by Wiki User

The law of apperception, proposed by Immanuel Kant, states that new experiences are interpreted in light of our existing knowledge and understanding. An example would be seeing a new type of fruit and categorizing it based on our previous knowledge of fruits. Another example is reading a new book and connecting it to themes or ideas we have encountered before.

The essential elements of a communication system include a sender who initiates the message, a message that is being transmitted, a channel through which the message is sent, a receiver who receives the message, and feedback, which is the response from the receiver to the sender.

How could it B true that matter and antimatter at start of big bang With little amount of matter left in end winning B enough 2 make up all we see today?

User Avatar

Asked by SpeedyMcWolf

In the early universe, matter and antimatter were created in equal amounts. As the universe cooled and expanded, there was a slight imbalance in favor of matter over antimatter. This allowed the matter to survive and form the structures we see today, while most of the antimatter annihilated with matter, resulting in the predominance of matter in the universe.

What is acceleration that occurs in a circular motion?

User Avatar

Asked by Wiki User

Acceleration in circular motion is the acceleration directed towards the center of the circle, known as centripetal acceleration. It is responsible for keeping an object moving in a circular path rather than in a straight line. The magnitude of centripetal acceleration is given by the formula a = v^2 / r, where v is the velocity of the object and r is the radius of the circle.

Why is stainless steel a bad conductor?

User Avatar

Asked by Wiki User

Stainless steel is not a bad conductor, but it is not as good a conductor as other metals like copper or aluminum. This is because stainless steel has a lower thermal and electrical conductivity due to its composition, which includes elements that inhibit the flow of heat and electricity.

If the diameter of a field is 1.6mm and you count forty consecutive cells from one end of the field to the other how wide is each cell in micrometers?

User Avatar

Asked by Wiki User

To find the width of each cell in micrometers, divide the diameter of the field by the number of cells counted. (1.6 mm / 40 cells = 0.04 mm per cell ). Convert to micrometers by multiplying by 1000: (0.04 mm * 1000 = 40 μm). Therefore, each cell is 40 micrometers wide.

Why does an egg become bouncy from vinegar?

User Avatar

Asked by Wiki User

When an egg is soaked in vinegar, the vinegar reacts with the calcium carbonate in the eggshell, causing it to dissolve. This leaves behind only the egg membrane, which gives the egg a bouncy texture because it becomes more flexible and has a higher water content.
