Answer:

it produces

Explanation:

a lot of waste

In an ecosystem,disadvantage of using wind as an energy source  is that it produces a lot of waste.

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Answer:

La rapidez media es 25 m/s en ambos casos.

Explanation:

Podemos definir como rapidez media al cociente entre la distancia total recorrida y el tiempo que se tardó en recorrer dicha distancia.

Así tenemos:

Rapidez media = Distancia/tiempo.

Entonces si el guepardo recorre 100m en 4 segundos, su rapidez media es:

Rapidez media = 100m/4s = 25 m/s

En el caso de que el guepardo recorre 50 metros en 2 segundos, su rapidez media será:

rapidez media = 50m/2s = 25m/s

Es el mismo resultado, pues recorrió la mitad de distancia en la mitad de tiempo.

Answer:

Inorganic.

Explanation:

The chemical change which describes the reactions of elements and compounds that, in general, do not involve carbon and typically take place in laboratories or industries is inorganic.

In Chemistry, an inorganic chemical reaction can be defined as a type of chemical reaction that occurs without a carbon-hydrogen bond.

On the other hand, organic chemistry deals with reaction that occur in the presence of carbon-hydrogen bonds such as hydrocarbons.

Answer and Explanation:Option A->The innermost layer of the earth is known as the core. It is divided into inner core and outer core. It comprises of a high concentration of nickel and iron.

Answer:

Weather such as raining has water molecules/droplets thats been evaporated from the ocean and other areas that's wet, the water will connect and soon the mass of the water will become heavy causing rainfall. Snow in another case has been caused to freeze from low climates creating a snow flake to fall from the sky. Hail is another case however the water that becomes ice is far more larger.

The variety of activities that take place daily in our atmosphere makes up for the weather.

The weather varies across the globe and changes over a few minutes, hours, days, and weeks. The troposphere, the region of Earth's atmosphere closest to the surface, is where most weather occurs.

Changes in air pressure determine the weather that occurs in a given place. The weight of the enormous quantities of air molecules that make up the atmosphere is what causes air pressure.

Usually, clear, blue skies are seen when air pressure is high. The high pressure prevents clouds from developing by causing air to flow down and fan out as it gets close to the ground.

Low air pressure causes air to move together before converging upward, where it rises, cools, and forms clouds.

Answer:

261.64 hz

Explanation:

speed = distance/ time

s= 200/0.78= 256.41 ms^-1

by using v= (f) x ( lambda)

256.41/ 0.98 = f = 261.64 hz

The frequency of the wave with the given wavelength, traveling the given distance at the given time is 261.6 Hertz.

Wavelength is the distance over which the shapes of waves are repeated.

From the wavelength, frequency and speed relation,

λ = v ÷ f

Where λ is wavelength, v is velocity/speed and f is frequency.

Given that;

First, we determine the speed.

Speed = Distance / time

Speed = 2.0×10²m / 0.78s

Speed = 256.4m/s

Now, we find the frequency.

λ = v ÷ f

f = v ÷ λ

f = 256.4m/s ÷ 0.98m

f = 261.6s⁻¹

f = 261.6Hz

Therefore the frequency of the wave with the given wavelength traveling the given distance at the given time is 261.6 Hertz.

A differentiated body is a body that has been heated to the point where it is are further from the sun larger have no solid surface and have many more moons  Smaller chunks of material vaporize completely as they pass through its atmosphere

Explanation:

A body is said to be differentiated when it has been heated to the extent where it is bigger, farther from the sun, has no hard surface, and has a lot more moons. Smaller pieces of the materials entirely evaporate as they pass through their environment.

An enormous, spherical celestial object known as a planet is neither a star nor a remain. The nebular theory, which states that an interstellar cloud collapses out of a nebula to form a young protostar that orbits the sun by a protoplanetary disk, is now the best argument for planet formation. By slowly accumulating material under the influence of gravity, or accretion, planets form in this disk.

The terrestrial planets Mercury, Venus, Earth, and Mars, as well as the planetary nebulae Jupiter, Saturn, Uranus, and Neptune, total at least eight planets in the Solar System. These planets all rotate around axes that seem to be inclined relative to their corresponding polar axes.

Answer:

28500

Explanation:

Force equation - F = m * a

F = 950 * 30

F = 28500

Answer:

19.2 m/s

Explanation:

From the question,

Velocity = displacement/time = d/t

V = d/t.................................. Equation 1

Average velocity = Total displacement/ total time

Total dispalcement = √(30²+60²) = √4500 = 67.08 m

Total time = 1.5+2 = 3.5 s.

Substitute these value into equation 1

V = 67.08/3.5

V = 19.2 m/s.

Hence the average velocity is 19.2 m/s

The parameter given for the car during transit is 30 m north in 1.5 seconds and drives 60 east in 2 seconds, we want to find the average velocity.

average velocity is 19.2 m/s

Solution

The expression for Average velocity is

Average velocity = Total Displacement/ Total time Taken...............Eqn 1

Total Displacement = √(30²+60²) = √4500 = 67.08 m

Total time = 1.5+2 = 3.5 s.

From the Equation 1

Average Velocity = 67.08/3.5

V = 19.2 m/s.

Therefore, the average velocity is 19.2 m/s

B) –1.1 × 1011 N

Explanation:

Since the second charge is 2 m away and is labeled q₂ = - 4 Coulombs. The third charge is 1 m away and is labeled q₃ = + 3 Coulombs, the electrical force between q₂ and q₃ is -1.1 × 10¹¹ N

To answer the question, we need to find the electrical force of attraction between two charges and this is given by Coulomb's law

This states that the electrical force of attraction between two charges, F is directly proportional to the product of the charges q and Q and inversely proportional to the square of their distance apart, d.

So, mathematically F = kqQ/d²

Now, given that there are three charges are on a line. A positive charge is on the far left labeled q₁ = + 6 Coulombs. The second charge is 2 m away and is labeled q₂ = - 4 Coulombs. The third charge is 1 m away and is labeled q₃ = + 3 Coulombs.

So, the electrical force of attraction between q₂ and q₃ is F = kq₂q₃/d² where

Substituting the values of the variables into the equation, we have

F = kq₂q₃/d²

F = 8.99 × 10⁹ Nm²/C² × (-4 C) × (+ 3 C)/(1 m)²

F = 8.99 × 10⁹ Nm²/C² × (-12 C²)/(1 m)²

F = -107.88 × 10⁹ Nm²/1 m²

F = -1.0788 × 10¹¹ N

F ≅ -1.1 × 10¹¹ N

Since the second charge is 2 m away and is labeled q₂ = - 4 Coulombs. The third charge is 1 m away and is labeled q₃ = + 3 Coulombs, the electrical force between q₂ and q₃ is -1.1 × 10¹¹ N

Explanation:

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased

The three factors are net force, the mass of the object and the direction of the force.

Acceleration is defined as the rate of change of velocity. It is also defined as the ratio of the net force acting on the body to the mass of the body.

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. and the direction of the force.

As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

Explanation:

Since it lateral acceleration is is its centripetal acceleration, the centripetal acceleration, a is given by

a = v²/r where v = speed of Dodge Viper GTS= 86.5 km/h = 86.5 × 1000 m/3600 s = 24.03 m/s and r = radius of skid pad = 61.0 m.

So, a = v²/r

= 24.028 m/s ÷ 61.0 m

= 0.394 m/s²

So, its maximum lateral acceleration is 0.394 m/s². Since g = acceleration due to gravity = 9.8 m/s²

a/g = 0.394 m/s² ÷ 9.8 m/s² = 0.04

So, a = 0.0402g

a ≅ 0.04g
