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

Cual es la rapidez media de un guepardo que recorre 100 metros en 4 segundos? ¿Y si recorre 50 m en 2 s?
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.

if a car exerts a area of 3m and a force of 9N what is the pressure exerted by car
Answer:
P = 3 Pa
Explanation:
Given that,
Force exerted by the car, F = 9 N
The area of the car, A = 3 m²
We need to find the pressure exerted by the car. We know that pressure is equal to the force per unit area such that,
[tex]P=\dfrac{F}{A}\\\\P=\dfrac{9\ N}{3\ m^2}\\\\P=3\ Pa[/tex]
So, the pressure exerted by the car is equal to 3 Pa.

What is an ecosystem?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.

Write a scientific explanation about weather or not a single cell constitutes a system. (CER)
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.
What is the weather like?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.

The reason that worlds like the Earth are differentiated is that Group of answer choices the heat of the Sun vaporized much of their solid material early on the heaviest chunks that hit early on were able to bore through solid rock to the center the continuing impacts on a growing protoplanet eventually melted the entire body large amounts of hydrogen and helium collect around such planets a little later in their history planetesimals with different types of composition hit at different times, with the heaviest ones hitting first
Answer:
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:
Hope it helps..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.
What is Planet?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.

When air warm up the air molecules move slower?
The cornering performance of an automobile is evaluated on a skid pad, where the maximum speed that a car can maintain around a circular path on a dry, flat surface is measured. Then the centripetal acceleration, also called the lateral acceleration, is calculated as a multiple of the free-fall acceleration g. The main factors affecting the performance of the car are its tire characteristics and suspension system. A Dodge Viper GTS can negotiate a skid pad of radius 61.0 m at 86.5 km/h. Calculate its maximum lateral acceleration.
Answer:
0.04g
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
What three factors affect the acceleration of an object?
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.
What is acceleration?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.
Therefore three factors are net force, the mass of the object and the direction of the force.

A car drives 30 m north in 1.5 seconds and drives 60 east in 2 seconds. What is the average velocity
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
