why can electromagnetic radiation travel through empty space?
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
Okay So Blink your eyes. Was work done? Explain your answer.
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.

Which of the following examples BEST describes the life characteristic of movement?
Human skin and lungs release carbon dioxide.
The oak tree takes in water and minerals for food.
The starfish cells divide and multiply to increase its size.
A cheetah races across the plain.
The statement that best describes the life characteristic of movement is human skin and lungs release carbon dioxide.
What do you understand by movement?Movement is an action of moving of any thing from one part or place to another part.
Life characteristic of the movement is shown by the human skin and lungs as skin opens and closes their pores time to time for the removal of gases and lungs also contracts and expands for the conversion of oxygen into carbon dioxide.
Hence, human skin and lungs release carbon dioxide is the life characteristic of movement.

Which position shows spring in the Northern hemisphere?
Explain how temperature and precipitation are affected by latitude and the sun's rays.
Answer:
Latitude and Temperature
At the equator, the Sun's rays are most direct. This is where temperatures are highest. At higher latitudes, the Sun's rays are less direct. The farther an area is from the equator, the lower its temperature.

What is the relationship between "freezing point" and "melting point"?
**Explain your thinking below using quotes from the text.**
~You will get reported if you answer with something else~
Answer:
The freezing point of a substance is the same as that substance's melting point. At this particular temperature, the substance can exist as either a solid or a liquid. At temperatures below the freezing/ melting point, the substance is a solid.
Explanation:
edge 2021
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
Some quotes from the text to support this is that: "Freezing point is the temperature at which a liquid freezes and melting point is the temperature at which a solid melts.

explain one or two things that adversely (negatively) affect the Earth's environment. How do you know that these things you're discussing are bad for the world around us?
Answer:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Answer:
Hello! The main thing I will be talking about today is two things that negatively affect the Earth's environment. Humans have impacted the physical environment is many ways, two being, overpopulation. Overpopulation is becoming a problem in this world. Accidental births are the main reason. Overpopulation can cause economic problems, over-farming, deforestation, and even water polluting. Second thing is, burning toxic fumes, and creating pollution. Pollution is a very, very bad thing. It can cause the atmosphere to fill up with fumes which aren't good for plants, humans, or animals. Pollution can take the form of chemical substances or energy, such as noise, heat, or light. There are four main types of air pollution sources: mobile sources, such as cars, buses, planes, trucks, and trains. stationary sources, such as power plants, oil refineries, industrial facilities, and factories. area sources, such as agricultural areas, cities, and wood burning fireplaces. I know the things I'm discussing are bad because, slowly the Earth is taking impact because of us. We need to make a better change and help our Earth.
