Match the part of the wave to its description

Answers

Answer:

Crest Highest Point of the wave

Trough Lowest Point of the wave

Amplitude the height from mid point to the crest or trough

Wavelength Distance from one crest to another

The match of the wave is

Crest ⇒ Highest point of the wave.

Trough ⇒ Lowest point of the wave.

Amplitude ⇒ Height from mid point to the crest or trough

Wavelength ⇒ Distance from one crest to another.

What is wavelength?

Wavelength the distance a wave travels in the time it takes a medium particle to complete one vibration. The letter k stands for it. The meter is its SI unit.

What is amplitude?

Amplitude can be referred to as the maximum displacement caused by the vibrating particle. A is the symbol for it. The meter is its SI unit.

What are some advantages and disadvantages to the acid rain management techniques?

Answers

Disadvantages of acid rain:
• Acid rain affects the fresh water ponds and lakes and destroys the aquatic life as some species of fishes are rare and may be extinct
• it can affect the trees particularly those that are high altitude
• It can damage historical monuments and buildings
•soil can be affected and can lead to deaths of good microbes

Advantages of acid rain:
• it makes holes in limestone below ground, which creates caves and places to store groundwater, as well as providing habitat for some species
• But the new study shows that sulfuric in acid may have benefits, limiting global warming by counteracting the natural production of methane gases by microbes in wetland areas.

Of course you should do more studying on acid rain but these are the simple ones

Acid rain management techniques include protect plants from acid rain on falling on them.

What is acid rain?

Rain formed when sulfur dioxide and nitrogen oxide react with chemicals in the atmosphere like water,oxygen and carbon dioxide to form sulfuric acid and nitric acid and then falling to ground containing these acids is called acid rain.

Acid rain alters the environment the environment tremendously by damaging plants and aquatic ecosystems.Plants require a specific pH of soil for their optimum growth and nutrition.

Due to acid rain, the acidity of soil increases rendering it unfit for plant growth.Similarly, pH of water also increases which affects the survival of aquatic ecosystems.

It also damages the the monuments made of metals, marbles .Taj Mahal made up of white marble has turned yellowish due to acid rain.

Heather is investigating the properties of light and how it travels. She places a glass on the windowsill and waits for the sun to shine on the glass and observes what happens. Next, she places a piece of cardboard in front of the glass. Which statement describes the results of her observations?

A Since glass is translucent, most of the light energy was reflected from the glass.
B When the cardboard was placed in front of it, the cardboard absorbed some of the light energy.
C The light from the sun was able to travel through the glass. When the cardboard was placed in front of the glass, it absorbed the light energy from the sun and converted it into heat energy.
D The glass absorbed the light and converted the light energy into heat energy. When the cardboard was placed in front of the glass, the heat was transferred from the glass to the cardboard.
When the sun hit the glass, the light energy was absorbed. When the cardboard was placed in front of the glass, it absorbed the light energy from the sun and converted it into heat energy.

Answers

Answer: C

Since glass is translucent meaning you can see through it, heat energy from the sun will easily pass through it. If you were to conduct this test with a piece of metal the heat would be absorbed by the metal making it extremely hot. In this instance when they put a piece of cardboard in front of the glass it would absorb the heat energy since it is not translucent.

Which of Newton's 3 Laws explains a rocket lifting off? *

Law of inertia
Law of Acceleration
Law of Action-Reaction

Answers

Answer:

Newton's Third Law of Motion

Explanation:

A rocket expels hot gases at a very high pressure very quickly, and these gases have lots of energy, and according to Newton's third law, every action has an equal and opposite reaction. So, expel lots of gas at a high rate, and the energy of the gases being pushed out propels the rocket upward. Hope that helps!

Newton's Third Law states that "every action has an equal and opposite reaction". In a rocket, burning fuel creates a push on the front of the rocket pushing it forward. This creates an equal and opposite push on the exhaust gas backwards.
