Answer:
potential energy (im positive that its right)
Which characteristic is related to kinetic energy but not potential energy
Answer:
kinectic is movement and potential is still
Explanation:
While kinetic energy of an object is relative to the state of other objects in its environment, potential energy is completely independent of its environment. Hence the acceleration of an object is not evident in the movement of one object, where other objects in the same environment are also in motion.
Answer:an object’s speed
Explanation:
The Bohr model of the atom suggest that the protons and neutrons are found in the nucleus and the electrons orbit the nucleus much line planets around the sun. How is our modern model of the atom different from this model?

The most stable group of elements on the periodic table is the?
A) halogens
B) noble gases
C) alkali earth metals
D) alkaline earth metals
Answer:
Noble Gases B
Explanation:
The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable.
Aly's science class was looking at bacteria through a microscope. Aly's teacher said some bacteria can be as small as 0.00365 cm long. What is the length of the bacteria written in scientific notation?
Answer:
[tex]0.00365\ cm=3.65\times 10^{-3}\ cm[/tex]
Explanation:
Aly's teacher said some bacteria can be as small as 0.00365 cm long.
In this problem, we need to write the length of the bacteria written in scientific notation. Any number can be written in the form of scientific notation as follows :
[tex]N=a\times 10^b[/tex]
a is a real no and b is an integer
In the given number, there are two zeroes before 3. We need to shift the decimal after 3. It can be done as follows :
[tex]0.00365\ cm=3.65\times 10^{-3}\ cm[/tex]
Hence, this is the required solution.
Describe what happens to kinetic energy of the molecules when temperature increases.
Answer:
When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
Explanation:
That is all I know.
How is kinetic energy of particles and temperature related
Answer:
The higher the temperature, the faster the particles move, the lower the temperature, the slower.
Explain why there is a difference in the thickness of the crust between the side of the moon facing the Earth and the side that faces away from the Earth?

Anita was using steel to make rusted sculptures. After building each sculpture, she caused the steel in the sculpture to rust by placing it into a tub filled
with salt water for eight hours. Anita wondered if steel would rust faster submerged in vinegar instead of salt water. To find out, Anita cut ten squares of
steel sheet metal and split them into two equal groups. She put one group of squares into a tub filled with salt water and the other group of squares
into a tub filled with vinegar. Once an hour for eight hours, Anita counted the number of rusted steel squares in each group.
What is the manipulated independent variable in Anita's experiment?
Answer:
The type of liquid in the tub (salt water or vinegar)
Explanation:
The manipulated independent variable in Anita's experiment is the type of liquid in the tub.
The independent variable is the controlled or manipulated variable in the course of an experiment. It can also be referred to as the 'cause' variable which has the capacity to produce 'effects' on another variable - the dependent variable.
In this case, the type of liquid the tub is filled (salt water or vinegar) will hypothetically affect the rusting period of the steel. Hence, the dependent variable is the type of liquid the tub is filled while the dependent variable would be the time it takes for the steel to get rusted.
As you were climbing a a mountain, you noticed that rocks were crumbling below your feet and moving down the mountain. What two processes did you observe?
Answer:
Weathering and erosion
Explanation:
Weathering can be explained as the breaking down of rocks/minerals on the surface of the Earth as a result of contact with biological organism, water, air and other factors
. There are 3 common types of weathering which are;
1) physical weathering
2) biological weathering
3) chemical weathering
Erosion can be regarded as a geological process, whereby earthen material are been transported away by natural forces, these forces could be wind as well as water.
Therefore, as you were climbing a a mountain, you noticed that rocks were crumbling below your feet and moving down the mountain. What is observed are weathering and erosion processes.
After the weakening and broken up of the rock by weathering then erosion transport the bit of the rock down the mountain as you are climbing, which means the "weathering process" breakdown and the "erosion process" involves the transport or movement of the bit of the rocks

Calculate the average atomic mass of antimony
Antimony-121 has a mass of 120.904 amu and a natural % abundance 57.21
Antimony-123 has a mass of 122.904 amu and a natural % abundance of 42.79
can you give the work aswell trying to understand how to do it
Answer:
Wow, now this one is a hard one, took me quite a while to figure it out but here it is
The abundances of the two isotopes is:
Antimony-121 = 57.2%
Antimony-123 = 42.8%

2. An all natural mosquito repellent
is trying to make its way into the
market. One arm is sprayed with the
repellent and one arm is not sprayed
with anything. After 3 hours, the
number of mosquito bites is counted. What is the control group
Answer:
The arm that was not sprayed with anything
Explanation:
The control group would be the arm that was not sprayed with anything.
The control group during an experiment is a group that forms the baseline for comparison in other to determine the effects of a treatment. The control group does not include the variable that is being tested and as such, it provides the benchmark to measure the effects of the tested variable on the other group - the experimental group. In this case, the experimental group would be the arm that was sprayed with the repellent.

12. If the particles of a liquid are always moving, why don't they all come apart from each other and become a gas?
Answer:
even though the particles of a liquid are moving, they are attracted to each other so they don't spread far apart to become a gas.
Explanation:
"but some do when they evaporate"
In liquids, the particles are allowed to move freely rather than the solid. The gaseous particles can move more freely than liquids.
Particles in liquids:In liquids, the particles are placed randomly and thus are allowed to move freely but they do not become a gas as liquids are slightly less compressible than gases. Even though the particles of a liquid are moving, they are attracted to each other so they don't just spread far apart to become a gas.

A scientist built a computational model to investigate what happens when magma comes into contact with the ground surface. In the model, the ground surface was 293K, whereas the magma was 1,500K. The model examined different depths of the magma away from Earth's surface and toward the core. Over a greater amount of time, more magma cooled. What form of heat transfer accounts for the magma cooling?
Answer:
Conductive heat transfer is most likely responsible for the cooling of the magma
Explanation:
The Earth's core is continuously cooling due to human's digging, allowing for more space and heat escape from the Earth's core. All magma closer to the core would have its heat absorbed by the core, hereby increasing its coolness.
This heat transfer process is common to conduction.

Why do we use Scientific Notation?
Answer:
Scientific Notation was developed in order to easily represent numbers that are either very large or very small. As you can see, it could get tedious writing out those numbers repeatedly. So, a system was developed to help represent these numbers in a way that was easy to read and understand: Scientific Notation.
Explanation:
Answer:
Working with very large or small quantities usually ends up being quite complicated. Scientific notation is a way to write numbers in an abbreviated way, making it easier to work with these numbers.
