what was Newtons first law of motion??
Answers
Answer:
Basically an object in motion or at rest will remain that way unless an outside force acts against it.
Explanation:
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia.
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. ... The third law states that for every action (force) in nature there is an equal and opposite reaction.

How does a balanced chemical equation prove the Law of Conservation of matter?
Answers
Answer:
Every chemical equation follows to the law of conservation of mass, which states that matter cannot be created or destroyed. When you have an equal number of atoms of an element is present on both sides of a chemical equation, the equation is balanced therefore it is following the law of conservation of mass.
Explanation:
Answer:
A balanced chemical proves the Law of Conservation of Matter because the law stats that matter cannot be created nor destroyed. so, in every chemical reaction the amount of matter will stay the same in the product as it did in the reactant.
In other words, balanced chem equations show that mass in conserved in chemical reactions

Which of the following events could increase Earth's temperature?
Question 2 options:
A. a decrease in the relative percent of greenhouse gases
B. planting more trees
C. widespread removal of tropical forests
D. a reduction in the use of fossil fuels
Answers
Answer:
The answer is C & A.
Hope this helped you out!^^
Temperature measures the average kinetic energy of particles of the substances. Therefore, the correct option is option C that is widespread removal of tropical forests.
What is temperature?Temperature is used to measure degree or intensity of heat of a particular substance. Temperature is measured by an instrument called thermometer.
Temperature can be measured in degree Celsius °c, Kelvin k or in Fahrenheit. Temperature is a physical quantity. Heat always flow from higher temperature source to lower temperature source.
We can convert these units of temperature into one another. The relationship between degree Celsius and Fahrenheit can be expressed as:
°C={5(°F-32)}÷9
A decrease in the relative percent of greenhouse gases, planting more trees and a reduction in the use of fossil fuels will decrease the temperature of the earth. Widespread removal of tropical forests increase the temperature of earth.
Therefore, the correct option is option C that is widespread removal of tropical forests.

How is a lunar eclipse similar to a solar eclipse? How are they different?
Answers
Answer:
they moon and sun are a factor in both of them
Explanation:
Answer:
From our perspective on Earth, two types of eclipses occur: lunar, the blocking of the Moon by Earth's shadow, and solar, the obstruction of the Sun by the Moon. When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. Also they are similar by An eclipse occurs when one celestial object obscures another celestial object. In the case of a solar eclipse, the moon moves between the Earth and the sun, thus obscuring the sun. A lunar eclipse occurs when the Earth moves directly between the sun and the moon. Either type of eclipse can be total or partial.

moderate amounts of precipitation
Answers
Answer: D : moderate amounts of precipitation
Explanation:
The one characteristic that temperate marine and temperate continental climates have in common is moderate amounts of precipitation. Thus, the correct option for this question is D.
What is Climate?Climate may be characterized as the long-term pattern of weather in a particular area. It is different from the weather in a way that can change from hour to hour, day-to-day, month-to-month, or even year-to-year.
According to the context of this question, A maritime climate is influenced by a nearby ocean. A continental climate is influenced by nearby land. The temperature of offshore currents affects nearby land areas.
A maritime climate is less extreme than a continental climate because the ocean moderates temperatures. Due to this, both temperate marine and temperate continental climates have moderate amounts of precipitation.
Therefore, the correct option for this question is D.

Researchers have been studying how emissions from both volcanoes and human activities, such as the burning of fossil fuels, impact the atmosphere. Both types of emissions contribute to the total CO2 levels in the atmosphere. Graph 2 shows that atmospheric CO2 levels have been steadily increasing over time. This increase in CO2 levels has been linked to the increase in global surface temperatures.
Identify the part of the slow carbon cycle in which the total amounts of carbon is most likely decreasing the most and explain why this decrease occurs.
Answers
Answer:
Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2. as u know decreasing means going down and increasing means going up. the reason why things decrease means something went wrong or something to happen to make it go down we all try to make things increase which means we try to make things go up instead of down. a lot of reasons is y things decrease is bc during the period of time something might go wrong or happen in a bad way that makes a lot of things decrease. for example like temperature when the temperature decreases it means it goes down and it might get cold but if the temperature increases it goes up so it might be ht or warm or maybe even cool. if something ever decreases it means during the period of time something bad happened and made it go down instead of up if something ever goes wrong that means something decreased. sometimes decreasing could be a good thing but most of the time it it bad but there are sometimes when decreasing is good but not all the time.
The part of the slow carbon cycle in which the total amounts of carbon is most likely decreasing the most is from 1960 to 1970.
What the given graph shows?Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2. As you know decreasing means going down and increasing means going up. The reason why things decrease means something went wrong or something to happen to make it go down we all try to make things increase which means we try to make things go up instead of down. A lot of reasons is why things decrease is because during the period of time something might go wrong or happen in a bad way that makes a lot of things decrease. For example, Temperature. When the temperature decreases it means it goes down and it might get cold but if the temperature increases it goes up so it might be hot or warm or maybe even cool. If something ever decreases it means during the period of time something bad happened and made it go down instead of up if something ever goes wrong that means something decreased.
