Explanation:
I took the test
Independent practice 6.GM.4.1. This maybe to random of a question but I need help please! It's about transformation, reflection, and rotation. If you are a teacher or anyone please help I'm struggling on this! (and I know this is not chemistry I had to choose one.)
Answers
Hey love! So I believe you’re asking if it’s transformation, reflection, or rotation. In this problem, it would be reflection! I can attach a visual example if needed, but imagine you’re flipping the shape like a pancake- first down, and then to the right. It should line up with the shape on the bottom. Does that make sense? I can find a different way to explain it if needed ! ^^

Why do you only see red when you look at a red apple?
Answers
Answer:
Light reflects off the apple and the light travels to the retina where special receptors transmit messages to the brain, producing the color red that we see. Some colors are reflected while others are absorbed, so you only see red when looking at an apple instead of green or purple.

stars are far away. can you describe their distance in ordinary terms?
Answers
Answer:
Light years
Explanation:
Stars are away from the earth millions of kilometres away. It is not convenient to express such a large distance in the units of km. So, the distance of stars from the earth is expressed in light years. One light year is the distance that light travels in one year in a vacuum.

People use hot air balloons to rise high above the ground and be pushed by air currents from one place to another. The diagram shows a hot air balloon.
A type of chemical reaction, called combustion, takes place between propane and oxygen in the burners.
a. Describe a likely result of this chemical reaction that allows a hot air balloon to rise.
b. Describe a design feature the distance a hot air balloon can travel. Explain your reasoning.
Answers
Fueled by propane cylinders, gas jets produce the hot air that fills the envelope (similar to ones you might use on a portable camping stove).
WorkingSince heated air rises, hot air balloons are functional. with the rest. As though it were floating in water, the balloon rises as a result of this. The balloon naturally starts to slowly deflate if the air is allowed to cool.The molecules in the air start to migrate and spread out as the air within the balloon is heated, which results in a decrease in the air's density. The heated air is pushed below the cooler, surrounding air. the warm air is pushed upward as a result of this.For more information on hot air balloon kindly visit to

Which of the following would occur if the Thrush population was to suddenly decrease?
a
The population of Eagles would increase
b
The population of Eagles would decrease
c
The population of Dragonfly would decrease
d
The population of corn would increase
Answers
Reasoning: Since Eagles directly eat Thrush, their populations would decrease.
The other answers are wrong because with the first choice, Eagles would not increase in population if one of their food sources were removed. For the third choice, Dragonflies wouldn’t increase. Since Thrush eat Dragonflies, the disappearance of Thrush wouldn’t hurt the population of Dragonflies. Lastly, The last option is wrong because corn isn’t reliant on animals to survive. If Thrush disappear, corn will not be affected. This leaves B. to be the answer.
What information does the periodic table give you?
Answers
The periodic table contains information about each of the known elements. It includes the name of each element, its atomic number, its atomic mass and its chemical symbol.
The periodic table is divided using groups (columns) and periods (rows).
Each specific group or period has a specific pattern in the elements.
The modern periodic table is arranged in order of increasing atomic number.
I’m not really sure what information what you were asking for but I hope this helps..
The modern periodic table was created by Dmitri Mendeleev with the main goal of showing rows and columns with a logic arrangement of chemical elements.
In each column, the groups, the elements have the same number of electrons in the outermost shells. While the rows are called periods or series.

Does a wave transport energy, matter, or both? Explain your answer in 1-2 sentences (Will give brainliest)
Answers
Answer in Explanation form
A wave carries its energy without transporting matter. Waves are seen to move into an ocean or lake, yet the water always returns to its resting position.
A wave transports energy, but not matter. Waves are created by the transfer of energy from one point to another, and they are able to transmit this energy over long distances without physically moving any matter.
What is a wave?A wave is a disturbance that travels through space and matter, transferring energy from one place to another. Waves can take many forms, including mechanical waves (such as sound waves and seismic waves) and electromagnetic waves (such as light waves and radio waves).
Waves are created by the transfer of energy from one point to another, and they are able to transmit this energy over long distances without physically moving any matter. For example, sound waves can transmit energy through the air without moving any air molecules, and light waves can transmit energy through empty space without moving any particles. However, waves can still have an impact on matter by interacting with it, such as when a wave causes an object to vibrate or when a wave of light is absorbed by a substance.

NEED HELP! ASAP! analyze and state the relationship between the independent and dependent variable by describing how the dependent variable reacted to the change in the independent variable. If you used a control, you shoukd compare the data to the control.
Answers
Answer: Depends on the experiment.
Explanation:
For any experiment, the fact remains that the independent variable always affects the measurement of the dependent variable. The independent variable is the factor in the experiment that you are changing. The dependent variable is, more often than not, the result of the change. Compare the relation between the two sets of data - probably graph it if it helps. The control data is the set of data gathered from the experiment where all the factors are not changed and are standardized. This is, in essence, the "original" data. Compare the changed data to this data. Hope it helped!
Write a summary of what you have learned about how incoming forces and outgoing forces are related (newton's cradle)
Answers
The relationship between incoming and outgoing forces in Newton's Cradle can be understood through the following concepts:
Conservation of Momentum: In a closed system with no external forces, the total momentum before a collision is equal to the total momentum after the collision. In Newton's Cradle, the momentum of the incoming ball is transferred through the stationary balls and eventually to the last ball, which swings outward with a momentum equal to the initial ball's momentum.
Conservation of Energy: Similarly, the total mechanical energy (kinetic and potential) in a closed system remains constant. In the context of Newton's Cradle, the kinetic energy of the incoming ball is transferred through the stationary balls, and eventually to the last ball, which swings outward with kinetic energy equal to that of the incoming ball. Potential energy is also involved as the balls swing and momentarily come to rest at their highest points.
Elastic Collisions: Newton's Cradle demonstrates nearly perfect elastic collisions, wherein both momentum and kinetic energy are conserved. In reality, some energy is lost to heat and sound, making the collisions slightly inelastic. However, the demonstration is still a useful approximation for understanding the transfer of forces.
Force Transfer: The incoming force exerted by the first ball is transmitted through the intervening balls to the last ball without causing any significant movement of the middle balls. This occurs because the balls are very close together and the time taken for the force to be transferred is minimal, allowing the middle balls to remain nearly stationary.
In summary, Newton's Cradle demonstrates the relationship between incoming and outgoing forces through the principles of conservation of momentum and energy, elastic collisions, and force transfer. The device provides a clear visual representation of these fundamental concepts in physics.

1156 g/L
= ________ kg/mL
Answers
The Answer is 0.001156.
1156 g/L = 1.156 kg/L
Since 1 L is equal to 1000 mL, we can convert kg/L to kg/mL by dividing by 1000:
1.156 kg/L = 1.156/1000 kg/mL
1.156/1000 kg/mL = 0.001156 kg/mL
Therefore, 1156 g/L is equal to 0.001156 kg/mL.
