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:
The transmitter changes the angle in which the wave is sent. The receiver detects the changes in the angle and decodes them.
Explanation:
In communication systems, information is typically encoded into a wave, such as an electromagnetic wave or a sound wave. The correct option is A.
The transmitter modifies the properties of the wave, such as its amplitude, frequency, or phase, to represent the desired information. These changes in the wave's form carry the encoded information.
The receiver then detects the modified wave and decodes the changes made to extract the original information. By analyzing the altered properties of the wave, the receiver can interpret the encoded information and reconstruct the message or data sent by the transmitter.
This process allows waves to carry information over long distances and enables various forms of communication, including radio transmissions, telephone signals, and digital data transfer.
Therefore, the correct option is A. The transmitter changes the form of the wave, and the receiver decodes the changes that have been made to the wave.

How are scientists studying the effects of space on the human body?
Answer:
The human body affects vision and bone density in space.
Explanation:
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.

The title is the journey of the ice cube. (change it if you want)
Main character - ice cube
There was an ice cube made by the water from the freezer in an ice shop.
The ice cube, with a bunch of other ice cubes, were taken to be packed and sold to a restaurant. The ice cube was excited to where he was going while the other ice cubes are just meh. Now that the ice cubes arrived, a restaurant worker stores the ice cubes in a cooler and later used to put ice in a lemonade. While the lemonade in a glass cup was carried outside the porch of the restaurant by the waiter, the ice cube was fascinated by the environment of the restaurant. The waiter finally serves the thirsty customer and the customer drank almost half of the lemonade but the ice cube did not get in the man's mouth. Instead the other ice cubes went. The ice cube feared the person. Shortly after checking his phone, the customer was about to reach on to the glass until the hands accidentally pushes the glass over and falls. The ice cube and the remaining ice cubes spread away with the wasted lemonade liquid. No one bothered cleaning up the ice cubes, only the glass shards because the floor is a smooth concrete. Outside was really hot from the sun anyways so it would melt the ice cube and sooner evaporate. As it was in liquid form, the "ice cube" was feeling relaxed because it was just chilling on the floor. And when it evaporates, the ice cubes becomes more fascinated since it goes up to the sky while having a sky-view from above.
That is the end.
You can add, edit or even not consider this one. But this is just an example to spark up your ideas. Sorry if I made some English mistakes.
Hope that it helped
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

A teacher pushes on a wall with a force of 125N but the wall does not move. Calculate the amount of work in Joules the teacher accomplished.
Answer:
The answer would be 0
Explanation:
The Formula for work is force multiplied by distance
W=F*D
The force is 125N times the distance and becase the teacher didnt move it would be 0, 125*0 = 0 so the answer is 0Joules

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.
Study the dashed arrows in the image.
A diagram of the Earth rotating on its axis. A red horizontal line through the center of the Earth shows the Equator. A double headed arrow runs vertically through the center of the Earth and is labeled Intended path. A line begins at the bottom right of the Earth, curves to pass through the center, and ends in the top right.
What causes the arrows to move in this direction?
Earth rotating
air moving to the poles
Earth’s equator
wind moving over short distances
Answer:
What the guy above me said
Explanation:
peepee poopoo yeah
The thing that causes the arrows to move in the given specific direction is known as the rotation of the earth on its axis. Thus, the correct option for this question is A.
What is the importance of an equator?The importance of an equator is determined by the fact that it is a reference point for navigation. It is just an imaginary line that significantly divides the Earth into two equal halves, and it forms the halfway point between the South Pole and the North Pole at 0 degrees latitude.
The rotation of the earth on its axis causes the specific area of its surface gets a turn to face and be warmed by the sun due to direct exposure. This is important to all life on Earth.
The sun affects everything from the weather we experience to the food we eat, and even our health. Due to this, a line begins at the bottom right of the Earth, curves to pass through the center, and ends in the top right.
Therefore, the thing that causes the arrows to move in the given specific direction is known as the rotation of the earth on its axis. Thus, the correct option for this question is A.
