why can electromagnetic radiation travel through empty space?

Answers

Answer 1

Answer:

hello

Explanation:

Electromagnetic waves are waves that can travel through matter or through empty space. ... However, when light travels in matter, it interacts with the atoms and molecules in the material and slows down. As a result, light travels fastest in empty space, and travels slowest in solids.

that's the summary

I don't need you telling me this isn't a real question also I need this kind of work so please don't put anything that isn't useful for my assignment .


In physics, work is defined as a force causing the movement—or displacement—of an object. In the case of a constant force, work is the scalar product of the force acting on an object and the displacement caused by that force. Though both force and displacement are vector quantities, work has no direction due to the nature of a scalar product (or dot product) in vector mathematics. This definition is consistent with the proper definition because a constant force integrates to merely the product of the force and distance.

Answer:

no work was needed. Blinking does not require using energy sometimes we blink without thinking.

Explanation:

Answer:

Yes work was done because muscles in your body contract and relax to make you move and blink. To just smile you use 32 or 36 muscles. The simplest movements are also sometimes to most complex.

Imagine that scientists have found a planet with an outer layer divided into plates made of hard, solid rock, but the mantle below the plates is made of hard, solid rock instead of soft, solid rock as it is on Earth.

Do you think plate motion would take place on that planet? Why or why not?

Answers

No because the way the plates move is because earth has soft rock under the surface

The layer of planets is made of crust, mantle, and core. The tectonic plate motion on the newly found planet will not occur as it has a hard and solid mantle.

What are tectonic plates?

Tectonic plates are defined as sold rocks that make up the mantle layer of the lithosphere of the planet. They are massive and irregular in shape that can move under high pressure and temperature conditions to form mountains and landscapes.

The plate tectonic of the planet is composed of hard, solid rock that will not be able to move or solid like that of Earth as they are hard enough to show the movement of sliding over each other unlike the soft, solid rock of Earth's lithosphere.

Therefore, the plate tectonic of the planet with hard, solid rocks will not show any movements.

Explanation:

Answer: The relationship between freezing point and melting point is that freezing point is at the temperature of when a liquid freezes and melting point is at the temperature when a solid melts which are both at the same temperature

Although R-rated movies cannot be viewed by anyone under the age of 17 unless accompanied by a parent, movie studios survey children as young as 9 to gauge their reaction to R-rated movies. The interest in this age group is due to the fact that many under-17 year olds actually view these movies. The Motion Picture Association of America has indicated that while the 12 to 17 age group is only 10% of the population, they make up 17% of the movie audience. Another reason for the interest in youngsters is the tie-in with toys that can aim for children as young as 4 years. Merchandise marketed by Universal for their movie "Mummy" is aimed at the 4 to 14 age group.Before movies appear on the screen, studios run preliminary tests. People are recruited out of movie lines or malls to participate in the preliminary screening in return for free movie tickets. The results of these tests can affect advertising, promotions and future sequels. People who saw the original movie are often surveyed during the planning phase of sequels to determine "...who are the most intense fans of the movie by age, gender, ethnicity, et cetera, and what drives their zeal." This information helps to guide the sequel.Recently Columbia Tristarinterviewed 800 people who had seen the original thriller "I Still Know What You Did Last Summer". Five hundred of these moviegoers were in the 12 to 24 age group, with 100 in the 9 to 11 group. An additional 200 African-Americans and Latinos were included in the sample, 150 between 12 and 24 years and 50 in the 9 to 11 group. Questions about the original movie pertained to their favorite character, other liked characters, most memorable scene, favorite scene and scariest scene.Before releasing "Disturbing Behavior", MGM/United Artistspreviewed 30-second commercials among 438 people age 12 to 20. They found that viewers ranked the standout scene as a woman bashing her head into a mirror and they found that these commercials were the most effective among the 15 to 17 year olds.Do you see sampling error playing any significant role in terms of make inference, statistically speaking from a researcher's perspective?
