Answer:

infrared waves, or infrared light, are part of the electromagnetic spectrum. People encounter Infrared waves every day; the human eye cannot see it, but humans can detect it as heat.

Explanation:

How does hot object produce heat?

The hot objects create hot air producing heat.
Movement of the hot object creates heat.
Molecules in the hot objects create friction to produce heat energy.
Heat is absorbed the object from the air around it.

Answers

The object can creat heat from energy and friction but in some cases that’s not the case.
When objects are heated, the movement between the particles of the matter increases. As a result, particles move and vibrate more faster. When this happens, the heat can be transferred by vibrations between particles. Hope this is correct. If yes, please give me the brainliest

B.Planets formed from large asteroids that had broken apart.
C.Planets formed from molten metal in volcanic eruptions.
D.Planets formed from small amounts of debris that were attracted together because of gravity.

Answers

Answer:

Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. ... When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material. At the center, gravity pulled more and more material in.

Planets formed from small amounts of debris that were attracted together because of gravity.

D. Planets formed from small amounts of debris that were attracted together because of gravity.

A dense cloud of interstellar gas and dust formed our solar system roughly a billion years ago. A solar nebula—a whirling, swirling disk of material—was produced when this dust cloud collapsed. Gravity drew more and more material into the center. The sun was still forming and planets had not yet been created when the solar system was very young. The solar system consisted primarily of gas and dust.

D. Planets formed from small amounts of debris that were attracted together because of gravity.

Which situation is an example of heat transfer by radiation?

Answers

Answer:

This type of transfer takes place in a forced-air furnace and in weather systems, for example. Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. An obvious example is the warming of the Earth by the Sun.

Answer:

the heat from the hotter to the colder region. Some common examples of Radiation are Ultraviolet light from the sun, heat from a stove burner, visible light from a candle, x-rays from an x-ray machine. All life on Earth depends on the transfer of energy from the Sun, and this energy is transferred to the Earth over empty space.

Sound, earthquakes, and waves in water are mechanical waves because they require a physical ______________________ to transport energy.



Disturbance


Electromagnetic field


Location


Medium

Answers

Answer is disturbance

Sound, waves are all propagation of energy. Transport of this energy require a physical medium. Thus option D is correct.

What is mechanical waves?

Mechanical waves are a form of energy transfer by oscillation of matter and they require a medium to propagate. Sound wave is a longitudinal wave which is only passing through a medium of air. Air disturbance causes these sound waves.

Longitudinal waves are those where the direction of oscillation of matter is along the direction of propagation.  Electromagnetic waves does not require a medium to travel.

Waves in water originates from the pressure difference in water earthquakes is caused by seismic waves which are transverse waves, where the oscillation of matter is perpendicular to the direction of propagation.

Hence, sound, earthquakes, and waves in water are mechanical waves because they require a physical medium.
