Explanation:
The diagram shows changes of state between solid, liquid, and gas. The atoms of a substance lose energy during a change of state. Before the change, the atoms are close together but are able to slide past one another.
A diagram has a triangle at center with gas on top, liquid on bottom right, solid on bottom left. An arrow from gas to liquid is labeled O, and an arrow from liquid to gas is labeled N. An arrow from solid to liquid is labeled P, and an arrow from liquid to solid is labeled Q. An arrow from solid to gas is labeled L, and an arrow from gas to solid is labeled M.
Which arrow represents the change of state described above?
°M
°N
°P
°Q
The answer is Q because atoms in water are not super spread out like in gas but if they are losing energy then it has to be turning to a solid where the atoms do not have much energy. In a solid the atoms are close together not being able to move past each other.
Answer:
the answer is q or the last one

True or False
An object will slow down and stop as long as no forces act upon it
Answer:
false
Explanation:
Understand Newton’s first law of motion. Experience suggests that an object at rest will remain at rest if left alone, and that an object in motion tends to slow down and stop unless some effort is made to keep it moving. An object will go on forever if there were no forces to act upon it. In space, a rocket will go forever at the speed it projects.
How can a wave carry information?
A. The transmitter changes the form of the wave. The receiver then decodes the changes that have been made to the wave.
B. The transmitter changes the angle in which the wave is sent. The receiver detects the changes in the angle and decodes them.
C. The transmitter changes the wave type between mechanical and electromagnetic. The receiver detects and decodes these switches.
D. The transmitter sends a wave. The receiver reflects this wave. The transmitter then decodes the changes made to the wave.

Answer:
Unlike genetic changes, epigenetic changes are reversible and do not ... DNA methylation works by adding a chemical group to DNA. ... Non-coding RNA may also recruit proteins to modify histones to turn genes “on” or “off.” ...
Explanation:
A car that brakes suddenly comes to a screeching halt. Is the sound energy produced in this conversion a useful form of energy? Yes or No------ Then explain why or why not. This is due tomorrow so please help!
Answer:
No, the sound produced by screeching brakes is not a useful form of energy, because it does not contribute to stopping the car.

How do you calculate net force if the forces are going in the same direction?
Answer:
If two forces act on an object in the same direction, the net force is equal to the sum of the two forces.In other words,When two forces act in the same direction, they add together.

What are factors within a region that affect or limit the physical environment?
Answer:Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource.
Explanation:hope this helps you

A scientist jumps into a pool off of a high dive. He thought it would be fun to calculate his acceleration during his dive due to gravity, but none of his calculations matched 9.8 m/s2, which he knows is the constant acceleration of an object due to Earth's gravity. His calculations were incorrect for his acceleration in the air as well as in the water.
Explain whether or not the diving scientist calculated acceleration due to gravity was most likely more or less than 9.8 m/s2 as well as your reason as why. Your answer should be three to four sentences in length and contain proper grammar and punctuation.
What is the frequency of this wave?
A. 4 Hz
B. 5 Hz

Contour lines on a topographic map, connect lines with:
Question 1 options:
the same rock layers
the same height above sea level
equal slope moving away from the line
equal amounts of rainfall
PLS NO LINKS I WILL REPORT YOU
IF THE ANSWER IS RIGHT I WILL GIVE YOU BRAINLIEST
Answer:
The same height above sea level.
Explanation:
The distinctive characteristic of a topographic map is the use of elevation contour lines to show the shape of the Earth's surface. Elevation contours are imaginary lines connecting points having the same elevation on the surface of the land above or below a reference surface, which is usually mean sea level.
