What waves are detected first because they move so fast.

Answers

Answer 1
The P in P-waves stands for primary, because these are the fastest seismic waves and are the first to be detected once an earthquake has occurred. P-waves travel through the earth's interior many times faster than the speed of a jet airplane, taking only a few minutes to travel across the earth.

Answers

The volume of Prism Y which is dilated to form prism X is 981 1/3 ft³

What is volume?

Volume is the amount of space occupied by a three dimensional shape or object.

The scale factor = height of prism Y / height of prism X

scale factor = 516 / 1013

Volume of prism Y = scale factor³ * 7425 ft³

Volume of prism Y = (516 / 1013)³ * 7425 ft³ = 981 1/3 ft³

outline the negative impact of droughts on the economy of South Africa​

Answers

Answer:

Explanation:

Droughts can have significant negative impacts on the economy of South Africa in several ways, including:

Agriculture: South Africa's economy is heavily dependent on agriculture, and droughts can severely affect crop yields, livestock production, and agricultural exports. This can result in food shortages, higher food prices, and economic losses for farmers and related industries.

Energy: Droughts can reduce the availability of water for hydroelectric power generation, which can lead to power outages and increased reliance on more expensive fossil fuels for energy production. This can result in higher electricity prices and reduced economic growth.

Tourism: Droughts can also affect South Africa's tourism industry, as water shortages can impact the availability of water-based recreational activities and wildlife viewing. This can result in lower tourist numbers, decreased revenue, and job losses.

Water supply: Droughts can lead to water scarcity and affect the availability and quality of drinking water, which can impact human health, productivity, and overall economic development. This can also result in increased costs for water treatment and transportation.

Mining: Droughts can affect mining operations, as reduced water availability can limit production and increase costs. This can result in lower profits and job losses in the mining industry.

Overall, the negative impact of droughts on the economy of South Africa can be significant and long-lasting, affecting multiple sectors and leading to economic losses, job losses, and reduced economic growth. Effective water management and drought mitigation strategies are needed to minimize the impact of droughts on the economy and ensure sustainable development.

1. The carbon in a buried peat bed has about 6% of the C-14 of modern shells. When the plants that now form the buried
peat were alive, they absorbed C-14 and probably had about the same amount of C-14 as modern shells, so about 94% of
the peat's original C-14 has decayed. What is a reasonable initial estimate of the age of the peat bed? Explain,
2. In sampling the peat bed, you must be careful to avoid any young plant roots or old limestone. Why?

Answers

Based on the percentage that has decayed of the peat's original C-14, a reasonable estimate of the age of the peat bed is 22,880 years.

We should be careful to avoid old limestone because it contains carbon that will help in finding the age of the peat bed sample. Same goes for the young plant roots.

What is an estimate of the age of the peat bed?

This can be found as:
= Half life of C-14 x Number of half lives that have passed

Number of half lives that have passed based on 6% being left of the orginal sample will be 4 half lives.

Estimate of age:

= 5,720 x 4

= 22,880 years.

Answers

Answer:

b

Explanation:

This shows a continuous process over years.

A 50 kilometer plain at the mouth of a river was formed at a rate of 1 millimeter per year is the best evidence of uniformitarianism. Hence, option B is correct.

What is uniformitarianism?

The belief that Earth has always changed uniformly and that the present holds the key to the past is referred to as uniformitarianism. Understanding Earth's history requires a grasp of uniformitarianism.

The landscape can change due to observable processes that occur over a long period of time, according to uniformitarianism. Examples include: * Mountain ranges can form in an area over millions of years even when earthquakes only occur periodically.

The theory of uniformitarianism was developed by Charles Lyell in the 19th century and is based on the writings of James Hutton. According to this hypothesis, the forces and processes that can be seen at the surface of the earth are the same ones that have sculpted the planet's terrain throughout natural history.

A wave has a wavelength of λ = 100 meters. It is passing over an area of the ocean that is 500 meters deep. Is it a deep-water or a shallow-water wave?

Answers

With a wave length of  λ = 100 and ocean depth of  500m, this wave is a deep water wave.

How to know a deep water wave

This type of wave that has the depth of the water to be more than the wavelength divided by 2.

That is depth > 100/2

If it was the other way round, that is wavelength is more than the depth, then it would be a shallow wave.

Therefore the answer to the question is the deep water wave.

What can a s waves pass through?

A: molten

Answer:

Explanation:

When an earthquake occurs, it makes seismic waves, which cause the shaking we feel. Seismic waves are essentially just the jiggling of the ground in response to the force put on the ground by the earthquake, similar to the way the jello in a bowl responds to a tap to the side of the bowl. There are three major kinds of seismic waves: P, S, and surface waves. P and S waves together are sometimes called body waves because they can travel through the body of the earth, and are not trapped near the surface.

Electromagnetic waves are invisible forms of energy that travel though the universe. However, you can "see" some of the results of this energy. The light that our eyes can see is actually part of the electromagnetic spectrum.

This visible part of the electromagnetic spectrum consists of the colors that we see in a rainbow - from reds and oranges, through blues and purples. Each of these colors actually corresponds to a different wavelength of light.

Electromagnetic waves

The sound we hear is a result of waves which we cannot see. Sound waves need something to travel through in order for it to move from one place to the next. Sound can travel through air because air is made of molecules.

These molecules carry the sound waves by bumping into each other, like dominoes knocking each other over. Sound can travel through anything made of molecules - even water! There is no sound in space because there are no molecules there to transmit the sound waves.

Electromagnetic spectrum

Electromagnetic waves are not like sound waves because they do not need molecules to travel. This means that electromagnetic waves can travel through air, solid objects and even space. This is how astronauts on spacewalks use radios to communicate. Radio waves are a type of electromagnetic wave.

Electricity can be static, like what holds a balloon to the wall or makes your hair stand on end. Magnetism can also be static like a refrigerator magnet. But when they change or move together, they make waves - electromagnetic waves.

Electromagnetic waves are formed when an electric field (which is shown in red arrows) couples with a magnetic field (which is shown in blue arrows). Magnetic and electric fields of an electromagnetic wave are perpendicular to each other and to the direction of the wave.

When you listen to the radio, watch TV, or cook dinner in a microwave oven, you are using electromagnetic waves. Radio waves, television waves, and microwaves are all types of electromagnetic waves. They only differ from each other in wavelength. Wavelength is the distance between one wave crest to the next.

Waves in the electromagnetic spectrum vary in size from very long radio waves the size of buildings, to very short gamma-rays smaller than the size of the nucleus of an atom. Yet their size can be related to their energy.

The smaller the wavelength the higher the energy. For example, a brick wall blocks visible light wave lengths. Smaller, more energetic, x-rays can pass through brick walls, but themselves are blocked by denser material such as lead.

While it can be said waves are "blocked" by certain materials, the correct understanding is that wave lengths of energy are "absorbed" by objects, or not. That is, wave length energy can be absorbed by certain material.

We use this knowledge in weather satellites as the atmosphere also absorbs some wave lengths while allowing others to pass through.
