Answer:
The mechanism of energy transport through a medium involves the absorption and reemission of the wave energy by the atoms of the material. When an electromagnetic wave impinges upon the atoms of a material, the energy of that wave is absorbed.
Why is it less noisy stomping on carpet than stomping on tile floors?
Answer:
Carpet softens harsh sounds and creates a quieter, more peaceful indoor environment. The installation of carpet and underlay is the only method available for eliminating excessive noise generated by floor impacts such as noise produced from footfalls, chairs scraped across the floor and objects dropped on the floor.
Explanation:
Carpets are thicker. That's why when you stomp it's more quieter because the impact of your foot will hit the thickness.
1) Describe the characteristics of each air mass.
a) An air mass develops near the Equator over the Caribbean Sea.
b) An air mass develops over a large land mass in the upper latitudes of the Northern Hemisphere.
(both need to be answered)
Answer:Continental air masses are characterized by dry air near the surface while maritime air masses are moist. Polar air masses are characterized by cold air near the surface while tropical air masses are warm or hot. Arctic air masses are extremely cold.
Explanation:
a. In subtropical areas like the Caribbean Sea and the Gulf of Mexico, maritime tropical air develops.
Explain about the characteristics air mass?Large air masses are capable of engulfing substantial portions of a continent's or a body of water's land surface. They penetrate the troposphere far up.The mass as a whole experiences similar temperatures and humidity levels. Nonetheless, as an air mass shifts away it from point of origin, its temperature and humidity do change.A: In subtropical areas like the Caribbean Sea and the Gulf of Mexico, maritime tropical air develops. It is connected to thunderstorms and warm, muggy weather.
B: Continental Large, high-latitude land masses, like northern Canada or Siberia, are where polar air masses form. It comes from northern Canada or Alaska in the Northern Hemisphere. It transports dry weather to the United States as it goes south. Low humidity and temperature are both present.

How can carpet be beneficial for reducing or blocking sound?
Answer:
The carpet is soft to step on by nature, but it also makes a good sound absorber. Carpets absorb sound because within their fibers and their clusters, trapped air pockets occur that prohibit them from vibrating.

“How can I describe and
compare objects and materials based on odor and taste?
Answer:
There are several ways to describe and compare materials based on odor and taste. This includes adjectives that describe the object/materials,
Explanation:
You can definitely describe and compare objects and materials based on odor and taste with the help of adjectives.
How many types of objects are there based on taste?There are five types of objects or materials that are based on the attribute of taste. This is because of taste receptors in the mouth sense the five taste modalities. It incudes sweetness, sourness, saltiness, bitterness, and savoriness (also known as savory or umami).
Scientists have classified odors into 10 basic categories: fragrant, woody/resinous, minty/peppermint, sweet, chemical, popcorn, lemon, fruity (non-citrus), pungent and decayed.
Both taste and odor of the materials and objects are represented with the help of a part of speech known as adjectives. Adjectives can be used to describe the qualities of someone or something independently or in comparison to something else, such as taste, color, odor, etc.
Therefore, you can definitely describe and compare objects and materials based on odor and taste with the help of adjectives.

I need help to know if I put enough information into my concept map or I need to add more?
Here are the instructions:
Your concept map will compare the manner in which energy is transferred by mechanical waves and electromagnetic waves. Include the following somewhere in your concept map:
types of energy transferred
medium required (if applicable) for transfer of energy
speed of energy transfer through various mediums (solid, liquid, gas)
Explanation:
One of the various ways that energy moves through space is by electromagnetic radiation.
Electromagnetic radiation includes the heat from a blazing fire, the sun's light, the X-rays used by your doctor, and the energy used to cook food in a microwave.
Waves are recognizable to anyone who has ever gone swimming in the ocean.
Electromagnetic waves are similar, however they differ in that they are made up of 222 waves that oscillate perpendicular to one another.
An oscillating magnetic field is one of the waves, while an oscillating electric field is the other.
Mechanical waves travel in a vacuum, whereas electromagnetic waves travel in a vacuum. Mechanical waves require the assistance of a medium to travel and can only travel at the speed of that medium whereas electromagnetic waves can pass through any medium.

How do you find the mechanical advantage of a gear?
Answer:
we can find by using formula load upon effort
Answer:
Calculate the mechanical advantage of a gear train. The mechanical advantage of a gear couple is given by MA = T_o/T_i where T_x is the number of gear teeth on gear x, o=output, and i=input. For stacked gear couples the overall mechanical advantage is the product of the individual mechanical advantages

compare the approximate distance from Hawaii and approximate age of the mountains in the Hawaiian–Emperor Seamount Chain. In your graph, be sure to include data from the seven mountains.
Explanation:
I don't have the data specific for this question, but I do have a general understanding of the science behind this and what the shape of this graph should look like.
The underwater mountain range and the Hawaiian Island chain were formed by a mantle plume hot spot, which is a hotter area in the mantle. Magma from the boundary between the lower mantle and inner core floated up due to its higher temperature and cooled to become a rock after reaching earth's surface, forming and island or volcano.
However, due to the movement of the Pacific Plate, this volcano moved away from its place precisely over the hot spot. Without heat from underneath, these volcanoes could no longer be active, rendering them extinct. The hot spot continued spewing lava, forming another volcano and repeating the cycle.
Over time, the rock from these volcanoes weathered and eroded away, causing them to sink under sea level and forming the mountain range and island chain.
Knowing the backstory behind Hawaii's formation, we can conclude that the islands further away from Hawaii, the biggest island with active volcanoes, are older in age.
I suspect it is a linear relationship!

4. Apply Concepts Which of the two weather stations below is experiencing higher air temperatures? Which is experiencing higher wind speeds?
Answer:
A high pressure system is a whirling mass of cool, dry air that generally brings fair weather and light winds. When viewed from above, winds spiral out of a high-pressure center in a clockwise rotation in the Northern Hemisphere. These bring sunny skies.
Humidity, air temperature and pressure, wind speed and direction, cloud cover and type, and the amount and form of precipitation are all atmospheric characteristics of the momentary conditions we call weather.

Give two examples of electromagnetic waves, explain how they are used, and explain why they are important in your life.
Points available:
1. First Type of EM wave (1 point), how it's used (2 points), why it's important (2 points)
2. Second Type of EM wave (1 point), how it's used (2 points), why it's important (2 points)
Answer:
Radio waves and the are various frequencies of radio waves are used for television and FM and AM radio broadcasts, military communications, mobile phones, ham radio, wireless computer networks, and numerous other communications applications. They are important because Radio waves are very widely used in modern technology for fixed and mobile radio communication, broadcasting, radar and radio navigation systems, communications satellites, wireless computer networks and many other applications.
Microwaves are widely used in modern technology, for example in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication. They are important because microwaves play an increasingly wide role in heating and cooking food. They are absorbed by water and fat in foodstuffs (e.g., in the tissue of meats) and produce heat from the inside. In most cases, this reduces the cooking time a hundredfold.
