Katie designed an experiment using a paint roller pan, sand, and water. The steps of the experiment are listed below.
Put 3 inches of moist sand on a paint roller pan.
Make a beach by scooping the sand towards the higher portion of the pan.
Pour water into the deeper end of the pan.
Tap on the water gently for 2 minutes to create waves.
Observe how the sand is displaced by the waves.
Katie’s experiment most likely represents the interactions between the

Moving a book to a lower shelf decreases potential energy.
True
False
Answer:
True
Explanation:
Moving a book so the potential energy of the system decreases is a true statement.
What is potential energy?A book's potential energy is reduced when it is moved to a lower shelf. A charge's electric potential energy is decreasing if it is traveling in the direction that it would typically go.
A charge's electric potential energy increases if it is pushed in the opposite direction from how it would ordinarily travel.
Since the potential at the Earth's surface is zero, gravity always has a tendency to draw items toward the planet's center, this causes the potential energy to be reduced.
Therefore moving the book to a lower shell change potential energy, which decreases.

asap help!! i’ll give brainlist and 50 points! ( if you answer them all )
Answer:
D
B
A
A
Explanation:
I hope this helps :)
Answer:
1 - D
2 - B
3 - A
4 - A
Explanation:
Hello There!
D=Distance
T=Time
S=Speed
For the first one we are given the speed and the time and we need to find the distance
To do so we multiply the two together( the two meaning the speed and the time)
They run 20 m per second and
if they run for 40 second
(20*40=800)
they will run for a total of 800m therefore the answer to the first one is D
for the second one we are given the distance and the time and we need to find the speed.
Looking at the formula chart we can find the speed by dividing the distance over the time
so speed = 80/5
80/5=16 so the speed is 16m/s (B)
For the third one we are given the distance and the time and we need to find the speed
Once again we can find the speed by dividing the distance over time
20/5=4 so the bunny hops 4m/s
For the last one we are given the speed and the distance and we need to find the time it took to get to the associated distance
another way we can find the time is by dividing the given speed by the distance
so time = 1500/250
1500/250=6 so it will take the space ship 6 seconds to reach a distance of 1500m

1. Using the grid provided, label the x-axis “Year". Label the x-axis with the years listed in picture one below.
2. Based on the sizes of the numbers for each population, create a scale on the two separate y-axes (similar to the snowshoe hare-lynx graph). Place the moose population on the y-axis on the left side of the x-axis and the wolf population on the y-axis on the right side of the x-axis.
3. Construct a line graph using the data from Table 2. Use a different coloured line for each population.
4.Give your graph a title. Create a legend for your graph so it is easy to read.
after your done with graph please answer this questions!
1. Describe the relationship between the moose and wolf populations.
2. What biotic and abiotic factors might influence the moose and wolf populations?
3.How would the carrying capacity for wolves be influenced if a large number of moose were killed by humans?
also please make sure the grid your using is the same as in picture two below!
Answer:
Here is the graph
Explanation:
Working on answering questions
Answer:
the moose and wolf population is increasing on 1960 and 1965.moose population is increasing but wolf population decreases on 1970.both are increasing on 1975 and 1980.moose population decrease but wolf population increases on 1985.wolf population decrease but moose population increases on 1990 and 1995.moose population decrease but wolf population increases on 2000 and on 2005.Explanation:
2.yes, biotic and abiotic factors might influence the moose and wolf populations.if there is more population of wolf ,moose population will be less
3. the carrying capacity for wolves be influenced if a large number of moose were killed by humans is that the number of wolf automatically decrease when a large number of moose were killed.as wolf is totally depend on moose.

Explanation:
If a hot liquid is poured into a cup, the cup will soon feel warm. How does the increase in temperature change the particles that make up the cup?
Answer:
Adding energy (heating) atoms and molecules increases their motion, resulting in an increase in temperature.
Removing energy (cooling) atoms and molecules decreases their motion, resulting in a decrease in temperature.
Energy can be added or removed from a substance through a process called conduction.
In conduction, faster-moving molecules contact slower-moving molecules and transfer energy to them.
During conduction the slower-moving molecules speed up and the faster-moving molecules slow down.
Temperature is a measure of the average kinetic energy of the atoms or molecules of a substance.
Heat is the transfer of energy from a substance at a higher temperature to a substance at a lower temperature.
Some materials are better conductors of heat than others.

What is a natural way to control an aphid population?
release ladybugs into habitat
praying mantis
insecticide
Answer:
I would say that the answer is A, or releasing ladybugs into a habitat.
Explanation:
This is the only "natural" way to control an aphid population. However, please note that as well as ladybugs, praying mantis's also eat aphids. But, the answer choice doesn't describe the option very well, so that is why I say that it is A.
Hope it helps!
The natural way to control an aphid population is release ladybugs into habitat. The correct option is 1.
What is Ladybug?Ladybugs are natural aphid predators that can consume large numbers of them, assisting in population control without the use of harmful chemicals.
A natural way to control an aphid population is to release ladybugs into the aphid's habitat.
Although praying mantises are natural predators of aphids, they are less effective at controlling their population than ladybugs.
Insecticides, on the other hand, are chemical treatments that can be harmful to both beneficial insects and the environment.
As a result, using insecticides to control aphid populations is not a preferred method, particularly in natural or organic settings.
Thus, the correct option is 1.
