[tex]\\ \sf\longmapsto Avg\: Velocity=\dfrac{Total\: displacement}{Total\:time}[/tex]
[tex]\\ \sf\longmapsto Avg\: Velocity=\dfrac{6800}{7200}[/tex]
[tex]\\ \sf\longmapsto Avg\: Velocity=0.9420m/s[/tex]
Answer:
0.9420m/s north
Explanation:
Given,
Displacement (Total) = 6800 metres(m)
Time = 2 hours
We need to convert hours to seconds.
2 hours = 7200 seconds
We know,
[tex]\sf\longmapsto \: Average \: velocity = \frac{Total \: Displacement}{Total \: time} [/tex]
Let's start solving!
[tex]\sf\longmapsto \: Average \: velocity = \frac{6800 \: metres}{7200 \: seconds} [/tex]
[tex]\sf\longmapsto \: average \: velocity = 0.9420\: m/s[/tex]
PLEASE HELP ME IF YOU DONE THIS BEFORE Part 1: Introduction
Title
Title your lab report with a few words that
summarize the lab investigation
Purpose
The lab report should begin with one or two
sentences that state the purpose of the
investigation what you want to see, practice, loam
about, or test. The purpose statement answers the
question "What am I trying to find out by doing this
experiment?"
The three most common types of labs are:
inquiry labs, in which you measure how
changing one variable affects another variable
discovery labs, in which you observe a scientific
phenomenon, perhaps for the first time.
forensic labs, in which you gather and analyze
data as evidence to build an argument in
response to a question, as in a court case,
All three types of labs give you an opportunity to
learn important scientific skills and concepts.
Question
At its core, science is about inquiry, or the act of
asking questions and seeking answers. Most labs
begin as the result of a question, which is why the
introduction of your lab report should include a
question. For example, suppose you notice that you
seem to play basketball better at the court in one
park than in another. After conducting research, you
realize that one of the surfaces of the court at the
park is different from that of your driveway. As a
result, you might formulate the scientific question
"What effect does the court surface have on the
height that the basketball bounces?" To answer this
question scientifically, you could perform several
experiments and gather data,
Hypothesis (or Prediction)
A hypothesis is an initial answer to a question, a
possible explanation or expectation based on prior
knowledge or research. Before starting most lábs,
you will formulate a hypothesis. It should be listed in
the introduction of your tab report
A good scientific hypothesis states conditions,
expected results, and possible reasons for those
results, For example, you could respond to the
basketball question with a hypothesis like "If the
court surface is smooth concreto, as the park's
court is, then the basketball will bounce higher,
because smooth surfaces have better contact with
the ball." Like this hypothesis, hypotheses are often
structured using the format "il then, because
which is described below.
The "it' portion of the hypothesis describes
something that you will change in the experiment
• The "then" portion of the hypothesis describes
what you think will happen as a result of that
change
• The "because" portion of the hypothesis
describes the ason why you think that change
will occur
In other laboratory activities you will be asked to
make a prediction. You will conduct background
research, then predict the outcome of a known
scientific process
Special Note about inquiry Labs
For inquiry labs, questions are generally
written in the form of "What is the effect of X on
Y?" Hypotheses will generally be in the form of
X [describe how you will change X during the
experiment), then Y will predict how y will
change in response), because give your
reason." In many inquiry labs the variables
lend themselves to a scatterplot (X-Y plot)
For anyone else who needs help just write an essay on what ionic bonds are. Then write what covalent bonds are. Then write the difference between them. It’s better than getting in trouble for using someone else’s work.
The student guide made it very confusing as if you were doing a project but it’s not, it’s just an essay.
Answer:
Was gonna use some links but {insert anger} brainly doesn't allow it.
Explanation:
There are primarily two forms of bonding that an atom can participate in: Covalent and Ionic. Covalent bonding involves the sharing of electrons between two or more atoms. Ionic bonds form when two or more ions come together and are held together by charge differences.
Search up: "Ionic bonds vs Covalent bonds" if you need more to write about

What aspect of a muscle cell allows
movement in the body?
A. its shape is short and blunt
B. fibers within the cell move back and forth allowing the
cell to stretch and shrink
C. there are no organelles which allows it to move easier
B is the answer
muscle cells are usually long and have many fibers that can contract and relax.
I'm 100% sure about my answer because I just learned about it :)
The aspect of a muscle cell allows movement in the body is fibers within the cell move back and forth allowing the cell to stretch and shrink. Thus option B is correct.
What is muscle cell?Muscle cell is defined as a unique animal cell that can shrink in size by utilizing a number of motor proteins that have been strategically placed inside the cell.
The cells that make up muscle tissue have the unique capacity to shorten or contract to cause movement of the bodily components.
There are three types of muscle cells.
Cardiac muscleSmooth muscleSkeletal muscleProtein filaments found in muscle cells slide across one another to create muscular contraction.
The configuration of these filaments gives skeletal and cardiac muscle their banded look.
They have a large number of mature mitochondria that supply the energy for muscular contraction.
Thus, the aspect of a muscle cell allows movement in the body is fibers within the cell move back and forth allowing the cell to stretch and shrink. Thus option B is correct.

The four main types of pest
Answer:
1) Insect
2) Mites
3) Rodents
4) Animals
5) Birds
Explanation:
1) These are significant and significant pests. Insects have three pairs of legs, two pairs of wings, a segmented body, and complex eyes and antennae that are unique to them. Insects are smart, extracting sap from plants, biting plant parts, burrowing into fruits, twigs, and leaves, attacking roots, barks, and blooms, among other things. Larvae, adults, and nymphs are the stages of insect pests that cause harm.
2) These are insect-like organisms with a soft body and four pairs of legs. The colour of these small organisms is red or pastel yellow. They feed on the plant's sap and attack the crops in large numbers.
3) This bug consumes a considerable amount of human food and causes widespread crop damage. They're also to blame for massive grain losses on fields, in warehouses, and in homes.
4) Wild boars, deer, elephants, buffalo, jackals, monkeys, and squirrels are among the animals that inflict direct harm to agricultural plants. They devour the plants and, as a result, squander a tremendous amount of food.
5) Birds devour grains and destroy crop plants. Crows, parrots, and sparrows are among the most common birds that prey on crops.

Answer:
True
Explanation:
Minerals are prone to destruction by different elements such as oxygen, heat, and acids treatment. The given statement is true. On treatment with these elements, minerals loose their properties.
What are minerals?
Minerals are the naturally occurring inorganic elements or compounds which posses an orderly internal structure and characteristics with the specific chemical composition, crystal form, and properties such as physical properties and chemical properties. Minerals differ from the rocks, which are the naturally occurring solids that are composed of one or more types of minerals.
Minerals show properties which can be lost by the treatment with different elements. Minerals have been found to be prone to destruction by the elements such as oxygen, heat, and acids. Minerals undergo chemical and physical change on treatment with these elements and form different products which show different characteristics than the parent minerals.

Tell the story of the predator/prey loop.
If the owl population goes up, then ...
Answer:
Below : )
Explanation:
Well, in most cases if the predator population rises most likely the prey population decreases this is because there is a big population of the predator which allows more of them to eat the prey so the prey decreases. Now when the prey decreases this again affects the predators because now the predators are limited to food so that causes many of them to decrease.
In this scenario, if the owl is the predator, as the population rises, its prey will decrease.
If the owl is the prey, the predators would most likely increase.
