Which best describes electromagnetic waves?
A. transverse waves made up of electric and magnetic fields
B. longitudinal waves made up of vibrations that move through matter
C. mechanical waves that travel as ripples in water
D. sound waves that can only travel in a medium
Answer:
A
Explanation:
hope this helps!!!!!!!
Answer:
A
Explanation:
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
they are transverse waves.

Instructions: Create a comic strip detailing the adventure of your character as the character is exposed to thermal energy, causing it to undergo phase changes from a solid, to a liquid, to a gas. Place drawings inside the boxes and written content on the lines below each box.
Your presentation must include the following:
• title and introduction of your character, including what substance it is made of
• source of thermal energy your character encountered (conduction, convection, and/or radiation)
• detailed description and/or diagram of the particle transformation from solid to liquid phase
• detailed description and/or diagram of the particle transformation from liquid to gas phase
( do not use the ice cube story)
girl how someone supposed to help you with that?!
Answer:
use water in the ocean getting precipitated and going up then make it fall off a mountain then make it freeze becuase it got stuck on the mountian
thermal energy happend when the water got precipitated
I hope it helps a bit

A book rests on a table. The force of gravity pulls down on the book with a force of 20 newtons. What prevents the books from accelerating downward at 9.8 m/sec2
A) The table presses back up on the book with an equal and opposite force of 20 newtons.
B) The table and the book together are accelerating downwards at 9.8 m/sec2
C) The table presses back up on the book with a force greater than 20 newtons.
D) The inertia of the book holds it up
Answer:
A
Explanation:
the forces are balanced that's why book experiences no net force
Answer:
A
Explanation:
Action/Reaction force!
Book on table, table on book. This particular reaction force is called the Normal Force. The table doesn't push back with more force, or there would be an unbalanced positive force, causing the book to accelerate upward. The forces must be in equilibrium if the acceleration is 0 (rest)
A/ Can someone help me, how can the third law of motion (Newton) help solve a problem / issue. be specific
b/ how can pushing off a wall on a skateboard demonstrate the third law of Newton. If needed use gravity, friction, and air resistance.
c/ How can dropping a ball on the ground demonstrate the third law of Newton. If needed use gravity, friction, and air resistance.

URGENT_____The diagram below shows the same model of the greenhouse effect... Select whether each process helps WARM UP or COOL DOWN the Earth's climate. *
The process A helps cool down the earth's climate, whereas the processes B and C, helps warm up.
What is meant by greenhouse effect?When the heat from the Sun is trapped by gases in the Earth's atmosphere, this process is known as the greenhouse effect.
Here,
The Earth is substantially warmer than it would be if there were no atmosphere as a result of the greenhouse effect.
One factor that makes the Earth a sustainable place to live is the greenhouse effect.
Since the manner that the interchange of incoming and outgoing radiation heats the globe is comparable to what happens in a greenhouse, the process is known as the "greenhouse effect."
The warming of the Earth's surface is a result of the greenhouse effect. A portion of the solar energy that enters the Earth's atmosphere is reflected back into space, while the remaining energy is absorbed and re-radiated by greenhouse gases.
Hence,
The process A helps cool down the earth's climate, whereas the processes B and C, helps warm up.

Now, imagine that you are helping a library move. You are lifting boxes of books onto a cart. Most of the boxes are full of many books, but one of the boxes was closed, only having a few books in it. You go to lift this box, not knowing it has less mass, with the same amount of force as you used to lift the full boxes. How will the acceleration of this box compare to the acceleration of a full box? Newton’s second law of motion tells us that if the force remains constant and the mass is decreased, the object will accelerate at a faster rate. Because the acceleration increases when the mass decreases, we say that acceleration is inversely proportional to mass.
Give an example of a situation where you might use the mathematical formula for Newton's second law to solve a problem. Explain how the formula would be useful in this situation.
