Does a wave transport energy, matter, or both? Explain your answer in 1-2 sentences (Will give brainliest)
Answer in Explanation form
A wave carries its energy without transporting matter. Waves are seen to move into an ocean or lake, yet the water always returns to its resting position.
A wave transports energy, but not matter. Waves are created by the transfer of energy from one point to another, and they are able to transmit this energy over long distances without physically moving any matter.
What is a wave?A wave is a disturbance that travels through space and matter, transferring energy from one place to another. Waves can take many forms, including mechanical waves (such as sound waves and seismic waves) and electromagnetic waves (such as light waves and radio waves).
Waves are created by the transfer of energy from one point to another, and they are able to transmit this energy over long distances without physically moving any matter. For example, sound waves can transmit energy through the air without moving any air molecules, and light waves can transmit energy through empty space without moving any particles. However, waves can still have an impact on matter by interacting with it, such as when a wave causes an object to vibrate or when a wave of light is absorbed by a substance.

In 3 paragraphs, describe how weathering changes the earth's surface. Please do not copy and paste.
Answer:
Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time.
The effects of weathering disintegrate and alter mineral and rocks near or at the earth's surface. This shapes the earth's surface through such processes as wind and rain erosion or cracks caused by freezing and thawing. Each process has a distinct effect on rocks and minerals. Mechanical weathering increases the rate of chemical weathering. As rock breaks into smaller pieces, the surface area of the pieces increases Figure below. With more surfaces exposed, there are more surfaces on which chemical weathering can occur. Mechanical weathering may increase the rate of chemical weathering.
Weathering, erosion, and deposition are processes that act together to wear down and build up the Earth's surface. These processes have occurred over billions of years. Weathering is any process that breaks down rocks and creates sediments. Weathering causes the disintegration of rock near the surface of the earth. Plant and animal life, atmosphere and water are the major causes of weathering. Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice.

In a vacuum, with no air resistance, how do 2 objects of different weights compare when falling?
Answer
hope it helps
Explanation:
In real life, heavier objects sometimes fall faster than light objects, but not because of gravity. Gravity makes all objects increase their speed at the same rate, regardless of how big they are. But if you drop 2 things outside, the air molecules may slow down one thing more than another.

the graph represents the decay curve of a radioactive isotope called strontium 90 what is the half life of this isotope
A. 8 years
B. 25
C. 50
D75
The half-life of strontium has been 25 years. Thus, option B is correct.
The half-life has been given as the amount of time required for an element to be reduced to half of its initial concentration. The half-life of the element has been given as:
\(A=\AA\;\dfrac{1}{2} ^\dfrac{t}{t1/2}\)
Where, the initial concentration of sample, is given by \(\AA\)
The final concentration of the sample is given by, A
The time of the reduction is given by t.
The half-life of the sample has been given by, t1/2
In the given graph, the initial concentration of the sample has been 100 grams. The time at which the concentration has been halved i.e. 50 grams is found after 25 years.
Thus, the half-life of strontium has been 25 years. Thus, option B is correct.

A small gap is left between the rails in the railway track. Analyze the reason.
Answer:
There could be several possible reasons for a small gap between rails on a railway track, such as:
1. Expansion joints: Railways are designed to allow the tracks to expand and contract with changes in temperature. To accommodate this expansion, small gaps are left between the rail ends and filled with expansion joints or plates.
2. Wear and tear: Over time, the rails may experience wear and tear due to heavy loads, weather conditions, and other factors. As a result, small gaps can appear between the rails.
3. Maintenance: During maintenance activities, rail tracks may be adjusted or replaced, which could lead to small gaps between the rails.
4. Environmental factors: Environmental factors such as soil shifts, earthquakes or other natural disasters can also affect the alignment of the rails, leading to small gaps.
These are some of the possible reasons for a small gap between the rails on a railway track.
Answer:
The small gap left between the rails in a railway track is intentional and serves a specific purpose. This gap is known as the rail joint, and it allows for the expansion and contraction of the rails due to changes in temperature. When the temperature changes, the metal rails will expand or contract, and if they were joined together tightly, they could buckle or become deformed, which could be dangerous for trains passing over them. The rail joint allows the rails to move slightly and prevent damage to the track.
Additionally, the rail joint also allows for maintenance and repairs of the track. If there were no gap between the rails, it would be challenging to replace a damaged rail or perform routine maintenance, such as tightening bolts or lubricating joints. With the rail joint, maintenance personnel can easily access and work on the track.
Overall, the small gap left between the rails in a railway track is intentional and serves a crucial function in ensuring the safety and reliability of the track.
1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.
Which phrase best describes the path of a light wave?
A. Parallel to the source
B. Perpendicular to the source
C. Spiraling around the source
D. Straight away from the source
Answer: D
Explanation:
Light waves travel in straight paths called rays. Unlike sound, where waves have to travel through matter to be heard, light waves do not have to travel through matter to be seen. Instead, rays travel in a straight path until they hit an object. A ray's straight path is the path of light

these days cloths made out of a mixture of synthetic fiber and natural fibers are more popular than those made purly out of synthetic fiber. Discuss the reason for this
Answer: Clothes purely made of synthetic fibers are not comfortable in a hot and humid environment as they don't have the property to absorb water or sweat quickly so their water-resistant property makes them unsuitable for hot humid environment .
Explanation:
Mixing of synthetic fiber and natural fibers enhances the properties such as strength, elasticity, and ease of ironing and washing. Generally in hot environments it is preferred to wear a mixture of synthetic and natural fiber than wearing only clothes made from synthetic fiber .
Moreover, mixing synthetic fibres with natural fibres enhances their properties, such as strength, elasticity and ease of washing and ironing. Hence, these days clothes made out of a mixture of synthetic fibres and natural fibres are more popular than those made purely out of synthetic fibres.

The color of a planet provides clues to its composition. From space, much of Earth looks blue because most of its surface is covered with water. The surface of Mars is much different from that of Earth. Much of its surface is made up of iron oxide, or "rust." Which color would you expect Mars to be?
Answer:
Mars would have different variations of brown, red, and orange.
Explanation:
Since different places of Mars have different substances or have different "ages" the color will be different.
Rust is formed because iron reacts to different substances, so there might be different weather patterns around Mars, and hence different colors of the rocks, iron, etc.
