Answer 2

The one that is not an interaction between an ecosystem is equilibrium. The correct option is C.

What is an ecosystem?

An ecosystem is comprised up of all the organisms and the physical environment in which they reside.

These biotic as well as abiotic elements are connected by nutrient cycles along with energy flows.

Photosynthesis introduces energy into the system, which is then incorporated basically into plant tissue.

Every living forms, encompassing humans, is a part of all these complex networks of interdependent relationships referred to as ecosystems.

A neat and healthy ecosystems clean the water, aids in the air purification , keep the soil in healthy condition, regulate the climate, recycle nutrients, and helps us with certain food.

Predation, parasitism, as well as herbivory are the four chief sorts of species interactions that takes place among organisms in an ecosystem.

In these interactions, one organism benefits while the other gets harmed. Competition encompasses both organisms that are harmed in some way as a result of their interactions.

Thus, the correct option is C as equilibrium is not basically interaction between ecosystem.

Explain the scientific theory of plate tectonics by describing how the movement of earths crystal plates cause both slow and rapid changes in earths surface, including volcanic eruptions, earthquakes, and mountain building

Answers

Plate tectonics rub against each other causing earthquakes sorry that’s all I know
Final answer:

Plate tectonics theory describes the motion of the Earth's lithosphere, which leads to geological phenomena such as earthquakes, volcanic eruptions, and mountain building.

Explanation:

Understanding Plate Tectonics

Plate tectonics is the scientific theory that explains the movement of the Earth's lithosphere, which is divided into tectonic plates. The mantle's slow motion drives the movement of these plates, leading to various geological phenomena. Tectonic plates move in different directions causing continents to gradually drift, leading to the formation of mountains, as well as causing earthquakes, and volcanic eruptions. This process is a fundamental aspect of geology and the formation of the Earth's topography. Moreover, plate tectonics acts as a heat distribution mechanism, cooling the planet by transferring heat from the interior to the surface.



Phenomena Caused by Plate Movement

Volcanic eruptions: Happen when molten rock from beneath the Earth's crust escapes through weaknesses in the crust, often at plate boundaries.

Mountain building: Occurs when tectonic plates collide and the land is pushed upwards.



All of these geological events showcase the dynamic nature of our planet, shaped significantly by the underlying movements of its tectonic plates.

describe a situation that demonstrates that water waved carry energy

Answers

In the ocean in the summer time when there are high tides and you see the BIG waves, in able for those waves to get so big, they need to have some type of energy transferred on to them so that the wave may be prosees.

The energy possessed by the water waves in ocean will be due to the gravitation of the moon and the sun.

What is wave energy?

Wave energy is a form of renewable energy that can be harnessed from the motion of the waves. There are several methods of harnessing wave energy that involve placing electricity generators on the surface of the ocean.

Due to the gravitation of moon tides, winds, and weather, waves can vary in size and strength. As waves roll through the ocean, they create kinetic energy, or movement.

This movement can be used to power turbines, which, in turn, create energy that can be converted into electricity and power. There are also several ways of harnessing wave energy that utilize the up and down motion of the waves to power pistons/turn generators.

Hence the energy possessed by the water waves in ocean will be due to the gravitation of the moon and the sun.

two sets of 3 consecutive integers have a property that the product of the larger two is one less than seven times the smallest set up and solve an equation that can be used to find both sets of intigers

Answers

Answer:
First set is 3,4 and 5
Second set is 1,2 and 3

Explanation:
Assume that the smallest number is n.
Since the three numbers are consecutive, this means that the other two numbers would be n+1 and n+2

Now, we know that the product of the larger two numbers is 1 less tan than 7 times the smallest.
This means that: 
(n+1)(n+2) = 7n - 1 .........> equation used to find the sets
n² + 2n + n + 2 = 7n - 1
n² + 3n + 2 = 7n - 1
n² + 3n + 2 - 7n + 1 = 0
n² - 4n + 3 = 0
(n-3)(n-1) = 0
This means that:
either n-3=0 ..........> n = 3
or n-1=0 ..........> n = 1

At n = 3:
The three numbers would be 3,4 and 5

At n = 1:
The three numbers would be 1,2 and 3

Hope this helps :)

Final answer:

To find the two sets of consecutive integers that satisfy the given property, we can set up and solve an equation. The equation is (x+1)(x+2) = 7x - 1. Solving this equation, we find two possible values for x: 1 and 3. Substituting these values, we find the two sets: {1, 2, 3} and {3, 4, 5}.

Explanation:

To find the two sets of consecutive integers, let's assign variables to the smallest integer in each set. Let's say the first set starts with x, so the consecutive integers in that set would be x, x+1, and x+2. Similarly, let's say the second set starts with y, so the consecutive integers in that set would be y, y+1, and y+2.

According to the given property, the product of the larger two integers (in this case, (x+1)(x+2)) is one less than seven times the smallest integer (in this case, 7x-1).

We can now form an equation: (x+1)(x+2) = 7x - 1.

To solve this equation, we can expand the left side and then simplify:

x^2 + 3x + 2 = 7x - 1

x^2 - 4x + 3 = 0

Now, we can factor the quadratic equation:

(x - 1)(x - 3) = 0

So the possible values for x are 1 and 3. Substituting these values back into the original equations, we can find the two sets of consecutive integers:

For x = 1, the integers are 1, 2, 3. And for x = 3, the integers are 3, 4, 5.

Therefore, the two sets of consecutive integers that satisfy the given property are {1, 2, 3} and {3, 4, 5}.

Particles of charge +75, +48, and -85μC are placed in a line. The center one is 0.35 m from each of the others. Calculate the net force on each charge due to the other two.

Answers

Final answer:

The net force on each charge due to the other two can be calculated using Coulomb's Law. The net force on the +75μC charge is 0.263 N in the positive x-direction, and the net force on the -85μC charge is -0.263 N in the negative x-direction.

Explanation:

To calculate the net force on each charge due to the other two, we can use the formula for the electric force between two charges: F = k x q1 x q2 / r2, where F is the net force, k is the Coulomb's constant (9 x 109 N m2/C2), q1 and q2 are the charges, and r is the distance between the charges.

Let's calculate the net force on the +75μC charge due to the +48μC and -85μC charges. The distance between the +75μC charge and the +48μC charge is 0.35 m. Substituting these values into the formula, we get F1 = (9 x 109 N m2/C2) x (75 x 10-6 C) x (48 x 10-6 C) / (0.35 m)2 = 0.263 N.

The net force on the -85μC charge due to the +75μC and +48μC charges is the same as the net force on the +75μC charge, but in the opposite direction, giving us: F2 = -0.263 N.

Therefore, the net force on the +75μC charge is 0.263 N in the positive x-direction, and the net force on the -85μC charge is -0.263 N in the negative x-direction.

What is the difference between Earth's magnetic and geographic poles? How do navigators take advantage of this?

Answers

Earth's magnetic poles are located near, but not quite exactly at, our planet's geographic poles (the "spin axis" on a globe). Compasses work as direction-finding devices because Earth has a magnetic field. The needle of a compass, itself a small bar magnet, points in the direction of the magnetic pole.

The difference between the positions of these two poles when viewed at different locations is defined as the magnetic declination which allows these angles for navigators to determine their true geographic position.

What is Magnetic declination?

Magnetic declination is also known as magnetic variation. It is the angle on the horizontal plane between magnetic north and true north which varies depending on the position on the Earth's surface and changes over time.

Declination is positive when the angle is east of true north and negative when it is west. It changes over time and with place.

Magnetic declination is caused by the complex shape of the Earth's magnetic field which defines to the use of a compass with its needle pointing north for navigation.

A sample of the material halite measures 3.18 cm long by 3.06 cm wide by 2.79 cm high and has a mass of 58.75 g. What is the its specific gravity?

Answers

Specific gravity = Density of an object/Density of water

Density = Mass/Volume

For the current scenario;

Density of halite = mass/(l*w*h) = 58.75/(3.18*3.06*2.79) = 58.75/27.148932 = 2.164 g/cm^3

Density of water ≈ 1000 kg/m^3 = 1 g/cm^3

Therefore,
Specific density of halite = 2.164 g/cm^3 / 1 g/cm^3 = 2.164

Specific gravity = Density of an object/Density of water


Density = Mass/Volume


For the current scenario;


Density of halite = mass/(l*w*h) = 58.75/(3.18*3.06*2.79) = 58.75/27.148932 = 2.164 g/cm^3


Density of water ≈ 1000 kg/m^3 = 1 g/cm^3

The wild type of a species represents the characteristics that prevail among individuals in natural conditions. For dogs, the wild type has a short body, upward-pointing ears, and a curly tail. Even though dachshunds are descended from the wild-type dog, they have long bodies, downward-pointing ears, and a straight tail. Which of these best explains how the shape of the dachshund came into being?


Humans bred various dogs over many generations to select for the dachshund's shape.


Humans created a gene for the dachshund shape, which they inserted into the DNA of a wild-type dog.


Natural selection led to the shape of the dachshund over many generations.


The unique shape of the dachshund spontaneously appeared during a single generation.

Answers

The correct answer is A) Humans bred various dogs over many generations to select for the dachshund's shape.

Indeed, wild dogs were bred, recently in time, to select certain characteristics (mostly physical aspects like ears, tails, etc) that were defined "prettier".
For example, at a certain point, a wild dog was born with a straight tail. This dog was interbred with another straight tail dog, as to pass this characteristic to their herds, and so on until today's shape.

Option B is not true because breeds were created far before the genetic manipulations and DNA were discovered.

Option C is not true because the natural selection actually brought to wild-type dogs, an evolution of wolves.

Option D is not true because not the whole shape of the dachshund appeared spontaneously, but just one characteristic that was progressively selected by humans.

The sound wave prodyced by a trumpet has a frequency of 440 hertz. What is the distance between successive compressions in this sound wave as it travels through air at STP?

Answers

   Wavelength = (speed) / (frequency)
so in order to answer this question, we need the speed of sound.
Without using my precious time to go look it up, I'm guessing thatthe speed of sound at STP is roughly  343 m/s .
If that estimate is accurate, then
         Wavelength = (343 m/s) / (440 /s)  =  0.78 meter .
Choice-#2 is much closer to this result than any of the others, so choice-2 must be it.
Actually, we can 'reverse engineer' Choice-#2 and find the numberit uses for the speed of sound.
       Speed = (wavelength) x (frequency)
                   = (0.75 m) x (440 /s)  =  330 m/s .
The author of the question used  330 m/s  for the speed of sound.

Which statement is true about the formation of bonds?

A. There is an overall release of energy when bonds form.
B. There is an overall energy increase when bonds form.
C. A bond is formed as atoms are split apart from each other.
D. Bonds are always first-order.

Answers

The answer is A. As a stable configuration is reached when atoms bond, so you are in a state of lower energy than not bonded.

Answer:

A. There is an overall release of energy when bonds form.

Explanation:

There is a general release of energy when bonds form. This energy is called bond energy.

Bond energy is involved in the breakdown or formation of one or more bonds between atoms of a molecule. Atoms bond with each other to achieve their electronic stability, that is, they move from a higher energy situation to a lower energy one. With this we can state that when the bond between atoms is formed, energy is released; therefore, its breakdown depends on energy absorption.

2) Water evaporates & rises turning into water vapour
3) When water vapour gets higher up, it cools & condenses to form clouds
4) Water falls from clouds as precipitation and returns to land/sea


So you can see that the water cycle results in the formation of clouds which produce rain.

The water cycle affects weather by regulating rains and water vapor in atmosphere.

What is  water cycle?

A biogeochemical cycle known as the "water cycle" depicts the constant movement of water on, above, and below the Earth's surface.

The amount of water on Earth stays relatively constant over time, but how it is divided up into the major reservoirs of ice, fresh water, saline water (salt water), and atmospheric water varies based on a variety of climatic factors.

Evaporation, transpiration, condensation, precipitation, infiltration, surface runoff, and subsurface flow are the physical processes by which water travels from one reservoir to another, such as from a river to the ocean or from the ocean to the atmosphere. As a result, the water transforms into liquid, solid (ice), and vapor.

The visible part comes from light. This is the part that is visible to the naked eye. Examples are ultraviolet rays, the sun, neon lights etc. To determine how hot something is, the visible portion is used. The brighter the object, the hotter it is.  Thus, the brightness of the stars can be determined by the color of the light emitted. The visible rays satisfy all the properties of transverse waves. However, light is considered a dual nature - it has wave and electron-like properties.

Suppose these waves represent the sound of a siren on a passing ambulance. Which wave represents the sound of the siren after it has passed you? Explain your answer.

The wave A has a higher frequency and wave B has a lower frequency.

I REALLY need help. Please.

Answers

The answer is wave B has a lower frequency.  Suppose these waves represent the sound of a siren on a passing ambulance. Wave B (lower frequency) represents the sound of the siren after it has passed you.  The ambulance moving towards the observer produces a higher than normal frequency, and the ambulance moving away produces a lower than normal frequency.

Answer:

The correct answer is "wave B has a lower frequency."

Explanation:

The Doppler effect is defined as the change in apparent frequency of a wave produced by the relative movement of the source with respect to its observer. In other words, this effect is the change in the perceived frequency of any wave movement when the sender and the receiver, or observer, move relative to each other.

This is the effect that occurs in this case. And it is explained as follows: When the ambulance approaches the observer, the wave "compresses", that is, the wavelength is short, the frequency high and, therefore, the tone of the perceived sound will be sharp. On the other hand, when the ambulance moves away from the observer, the wave "decompresses", that is, the wavelength is long and the frequency low.

Then the correct answer is "wave B has a lower frequency."

How to find acceleration with mass coefficient of friction and applied force

Answers

If by theta you mean the angle at the base of slope on which is the body laying, and you want to calculate minimal theta for which the blocks starts to slide.

Final answer:

To find acceleration with mass, coefficient of friction, and applied force, we can use Newton's second law and the formula for frictional force. The applied force can be calculated by subtracting the force of friction from the net force.

Explanation:

To find acceleration with mass, coefficient of friction, and applied force, we can start with Newton's second law. Newton's second law states that the net force on an object is equal to the mass of the object multiplied by its acceleration: F_net = m * a. In the case of friction, we can use the formula for frictional force: F_friction = µ * N, where µ is the coefficient of friction and N is the normal force.

The normal force can be calculated as the product of mass and acceleration due to gravity: N = m * g. The applied force can be calculated by subtracting the force of friction from the net force: F_net - F_friction = F_applied.
