ecosystem; hurricanes and tornadoes; catastrophic events.; Fooding; moving water; soil
Explanation:
After using the word bank to fill in the blanks in the passage, the passage reads;
"The organisms and environments that make up a community called an ecosystem are constantly changing. Sudden and violent events, such as hurricanes and tornadoes that often cause these changes are called catastrophic events. Fooding results when rainfall exceeds the holding capacity of a drainage system. The energy of the fast-moving water and the layers of sediment carried by it can uproot or bury plants, reshape the soil and destroy roads and buildings."

A car stops with an acceleration of -20 m/s/s in 8 seconds. How far did it go while stopping?
Answer:
640 m.
Explanation:
The following data were obtained from the question:
Acceleration (a) = –20 m/s/s
Time (t) = 8 s
Final velocity (v) = 0 m/s
Distance (s) =.?
Next, we shall determine the initial velocity (u) of the car. This can be obtained as follow:
Acceleration (a) = –20 m/s/s
Time (t) = 8 s
Final velocity (v) = 0 m/s
Initial velocity (u)
a = (v – u) / t
–20 = (0 – u) / 8
–20 = – u / 8
Cross multiply
–20 × 8 = – u
– 160 = – u
Divide both side by – 1
u = – 160 / – 1
u = 160 m/s
Finally, we shall determine the distance travelled by the car before stopping as follow:
Time (t) = 8 s
Final velocity (v) = 0 m/s
Initial velocity (u) = 160 m/s
Distance (s) =.?
s = (v + u)t /2
s = (0 + 160) × 8 /2
s = (160 × 8) /2
s = 1280 / 2
s = 640 m
Therefore, the car travelled 640 m before stopping.

a runner covers the last straight stretch of the race in 4 s. durning that time, he speeds up from 5 m/s to 9m/s what is the runners acceleration in this part of the race?
Answer:
The runner's acceleration was [tex]1\ m/s^2[/tex]
Explanation:
Constant Acceleration Motion
It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.
Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:
[tex]v_f=v_o+at[/tex]
Solving for a:
[tex]\displaystyle a=\frac{v_f-v_o}{t}[/tex]
The runner speeds up from vo=5 m/s to vf=9 m/s in t=4 seconds, thus:
[tex]\displaystyle a=\frac{9-5}{4}[/tex]
[tex]\displaystyle a=\frac{4}{4}=1[/tex]
The runner's acceleration was [tex]1\ m/s^2[/tex]
What is part of the fourth stage in the process of technological design?
O rebuilding and retesting a product
O analyzing the results of a prototype
establishing criteria for a successful product
identifying and defining a problem or need
Answer:
It is A.
Explanation:
Got it right on Edge 2022.
Rebuilding and retesting a product is part of the fourth stage in the process of technological design, therefore the correct answer is option A.
What are the stages of technological design?There are mainly five stages of the technological design
Identifying the issue that needs to be solved is the first step in every problem-solving process.
The second stage is to imagine; during this phase, a designer would generate several concepts and conduct research on potential creations. They must pick a handful of their greatest concepts and then narrow it down to the best.
The chosen product from the imaging stage is planned in the third stage. This process involves designing and drawing the product so that it may be turned into a model or prototype while taking into account the constraints they have to deal with.
Testing, evaluating, and modifying the product are the fourth stage. The designer can determine what they appreciate about their product and what they could change by making a model or prototype of it. Through product testing, this is discovered. If adjustments are required, the designer will repeat the entire procedure until they are satisfied with the final result.
The sharing of your solution is the fifth step. To gather comments, discuss your ideas with others, and enhance your product, you showcase your solution. You might show your answer to a bigger audience in later stages after you've gone through the design process a few times. This is comparable to how World of Inquiry students modifies their homework numerous times before presenting them during the expedition.
Thus, Rebuilding and retesting a product is part of the fourth stage in the process of technological design, therefore the correct answer is option A.

What role do electrons play in creating intermolecular forces?
The electrons repel positively charged molecules
Electron movement creates partial charges in different regions of molecules
They don't play any role
Electrons prevent dipole dipole interactions
Answer:
Electron movement creates partial charges in different regions of molecules.
Explanation:
The electrons play a role in the creation of London forces, which are intermolecular forces produced by the movement of the electrons in the atoms and molecules. The distribution of electrons will produce the formation of a temporary dipole, generating a partial charge in the atoms, which can induce a dipole into a subsequent atom (creating again partial charge), and so on.
Hence, the correct option is the second option: Electron movement creates partial charges in different regions of molecules.
I hope it helps you!
The role played by electrons in creating intermolecular forces is that electron movement creates partial charges in different regions of molecules.
Molecules are held together by intermolecular forces. There are several kinds of intermolecular forces such as;
Dipole - dipole interactionDispersion forcesHydrogen bonding etcIn all the kinds of intermolecular interactions mentioned above, interaction between molecules is made possible by movement of electrons which creates temporary or permanent dipoles in molecules due to partial charges in different regions of molecules.

In a scientific test conducted in Arizona, a special cannon called HARP (High Altitude Research Project) shot a projectile straight up to an alti-tude of 180.0 km. If the projectile's initial speed was 3.00 km/s, how long did it take the projectile to reach its maximum height?
Answer:
It took the projectile 120 s to reach the maximum height.
Explanation:
Given;
maximum height of the projectile, s = 180 km = 180,000 m
initial speed of the projectile, u = 3 km/s = 3000 m/s
final velocity at maximum height, v = 0
Apply the following kinematic equation for average velocity of the projectile;
[tex]s = (\frac{v+u}{2} )t\\\\(v+u)t = 2s\\\\t = \frac{2s}{v+u} \\\\t = \frac{2*180,000}{0+3,000}\\\\ t = 120 \ s[/tex]
Therefore, it took the projectile 120 s to reach the maximum height.

Davien and Jackson are headed to a beach that is 50km from school. At noon, Davien leaves his house that is 10 km closer to the beach than the school is and moves at 40 km/h. Jackson starts from school at 12:30 P.M. and moves at 100 km/h. What time does Davien reach the beach? *
Answer:
They both arrive at 1:00 PM
Explanation:
Amount Davien has to drive : 40km
Amount Jackson has to drive = 50km
Davien moves at 40km/h,
Therefore, it only takes Davien 1 hour to get there.
12:00 PM + 1 hour = 1:00 PM
Jackson moves 100km/h
He needs to drive 50 min, so 50/100 = 1/2
It takes him half an hour, or 30minutes
If he leaves at 12:30, then he gets there at 1:00 PM
You are warming a pot of ice. Explain what happens to the temperature when the water reaches its melting point and boiling point.
Answer:
Frozen water molecules vibrate more and more until they break free of the ice crystal. Liquid water molecules move faster and faster until they break free of the liquid.
Until all the bonds keeping the molecules in a crystal structure are broken, nothing can be done to raise the kinetic energy of the molecules in the liquid state. Thus, the temperature doesn't change until all the ice has melted. When water is heated to boiling point, the same thing occurs.
What are the melting point and boiling point?Melting point, the temperature at which a pure substance's solid and liquid states can coexist in equilibrium. A solid's temperature rises when heat is added to it until it reaches the melting point. The solid will then become a liquid with no change in temperature with the addition of more heat.
The temperature at which the pressure of a liquid exerted by its surroundings equals the pressure of the liquid's vapor is known as the boiling point. At this temperature, the addition of heat causes the liquid to turn into its vapor without rising the temperature.

A 25.1 kg boy climbs to the top of a 11.08 m tall water slide at an amusement park. He carries a 2.94 kg rubber ball with him. Taking the bottom of the slide to be the zero point, what is the gravitational potential of just the boy in joules? (do not include units)
Answer:
3080
Explanation:
Potential energy is the energy stored or contained in a body as a result to its relative position to other objects, an example is an object that is placed at a height above the ground thereby experiencing gravitational energy.
Potential energy = mass × gravity × height
Given that: height = 11.08 m, gravity = 9.81 m/s² and mass = mass of boy + mass of ball = 25.1 + 2.94 = 28.34 kg
Potential energy =28.34 × 9.81 × 11.08 = 3080

Use the information from the graph to answer the question. What is the acceleration of the object?
m/s2
The acceleration of the object is determined as -2.5 m/s².
What is acceleration?Acceleration is the rate of change of velocity with time.
Mathematically, acceleration is given as;
a = Δv/Δt
a = (v₂ - v₁)/(t₂ - t₁)
where;
v₂ is the final velocityv₁ is the initial velocityt₂ is the final timet₁ is the initial timeFrom the graph;
the initial velocity = 40 m/s
the final velocity = 10 m/s
the final time = 12 seconds
the initial time = 0 second
acceleration = (10 - 40) / (12 - 0)
acceleration = -30/12
acceleration = -2.5 m/s²

Answer:
Ep = 0.6095 [J]
Explanation:
As defined in the problem statement, potential energy is defined as the product of mass by gravity by height. But first we must convert all the values given to measures of the international system (SI)
g = gravity = 10 [m/s^2]
h = elevation = 40 [ft] = 12.19 [m]
m = mass = 5 [g] = 0.005 [kg]
Ep = potential energy [J]
Ep = 0.005*10*12.19 = 0.6095 [J]
