Answer:

Gears A and B work together. Gear A turns 30 times when Gear B turns 45 times. When Gear B turns 12 times, how many times does Gear A turn?

We use Kepler's third law to find the correct answer is:

Kepler's third law is a direct application of second Newton's law the motion of the planets around the Sun, if we assume that the orbit is circular the deduction is

            F = m a

where F is the force of attraction between the Sun and the planet, m is the mass of the planet and a is the ccentripetal acceleration.

The force is given by universal gravitation law, which says that the force of attraction between two bodies is directly proportional to the mass of the bodies and inversely proportional to the square of the distance between them, this force is attractive

          F = [tex]G \frac{M \ m}{r^2}[/tex]

where G is the universal constant of attraction, M the mass of the Sun, m the mass of the plant and r the distance between them

From kinematics we know the expression of the centripetal acceleration

          a = [tex]\frac{v^2}{r}[/tex]

we substitute

         [tex]G \frac{M \ m}{r^2 } = m \frac{v^2}{r}\\G \frac{M}{r} = v^2 \\[/tex]

As we assumed a circular orbit, the velocity of the planet in the orbit is constant, so the kinematic relations of uniform motion can be used.

The distance traveled by the planet is the length of the circle

       d = 2π r

       v = d / T

where T is the period of the orbit

       v = 2π r / T

we substitute

       [tex]G \frac{M}{r} = \frac{4 \pi ^2 r^2 }{t^2}\\T^2 = ( \frac{4 \pi ^2}{G \ M} ) \ r^3[/tex]

The year is the duration of the period of the planet's orbit around the Sun, with the previous expression it is observed that the period (year) increases when the radius of the orbit increases with a power of 1.5, in summary the planets more far away has duration of the greater anus

The constant in parentheses is inversely proportional to the greater of the Sun, that is, for more massive stars the period decreases

The period is in dependent on the mass of the planet, therefore any object at the same distance has the same duration of the period or the year of the planet.

In conclusion we use Kepler's third law to find the correct answer is:

From what I remember from my science class.

Answer:

AC does more than just keep you cool

Explanation:

For most people, the most important function of an air conditioner is its cooling power. However, cooling is in reality just one of the 3 vital functions of an AC system.

Most air conditioning systems use underground pipes to store and reject heat. To generate a climate in a room that is comfortable for people, air conditioning is mostly used.

The term "air conditioning" is frequently used to refer to the machinery employed in the process of eliminating heat, cold, plus moisture from the inside of a populated place.

The exterior unit's compressor liquefies the refrigerant during cooling to remove heat. Conversely, while heating a room, heated pressure gas produced by the outside unit's heat exchanger or compressor is condensed enough heat the air. Most air conditioning systems use underground pipes to store and reject heat. To generate a climate in a room that is comfortable for people, air conditioning is mostly used.

Therefore, to generate a climate in a room that is comfortable for people, air conditioning is mostly used.

Explanation:

Electronegativity will decrease the further you go down the periodic table and will increase from left to right. This makes fluorine the most electronegative just for reference.

Ex: Ca and Ga are on the same period but Ga is closer to the right so it’s the most electronegative

       If I was the moon, I would say that space is amazing. Past the years, I had been walked on by many people. I think they are called astronauts. The first person that put their feet on me was Neil Armstrong. He had a white thick coat and a helmet. I had been flagged by Buzz Aldrin but, the flag been flat on the ground since the moment Aldrin and Neil Armstrong lifted off. I couldn't do anything about it but, that flag made me feel special. I remember that the flag had about 50 white stars on the corner, in the corner was filled with blue where the stars were, red, white stripes. I shine because my surface reflects light from my friend, the sun. Many people ask me, "Do you always look the same?" No, everyone sees the same phases of me, the moon. I go through a process called moon phases. They are first Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, Waning Crescent, New Moon. I rotate on my axis. One rotation takes nearly as much time as one revolution around Earth I believe. During the day, I go the the other side of the earth, where the Earth's shadow is. Honestly, I enjoy being the moon. It's fun and I enjoy the white little twinkling stars beside me. I like seeing that little world move.

According to the electronic configuration and trends in the periodic table,atom which has largest atomic radius in each pair are Al,Na,S,O,Cl,Ca respectively.

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

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:

Plasma is a substance which is extremely hot. The heat present in plasma, a gas, is provided as energy in order to split electrons and protons apart. Therefore, ions and electrons are formed as products.

Explanation:

The state of matter  of the substance where in the electrons and protons are separated from the atom is plasma.

Matter in chemistry, is defined as any kind of substance that has mass and occupies space that means it has volume . The matter is composed up of atoms which may or not be of same type.

Atoms are further made up of sub atomic particles which are the protons ,neutrons and the electrons .The matter can exist in various states such as solids, liquids and gases depending on the conditions of temperature and pressure.
