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 1

Answer:

The answer is C & A.

Hope this helped you out!^^

Answer 2

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.

A pitcher throws a softball toward home plate. When the ball hits the catcher’s mitt, its horizontal velocity is 32 meters/second. The softball’s velocity goes to 0 meters/second in 0.8 seconds when caught. If the softball has a mass of 0.2 kilograms, what’s the force of the impact? Use F = ma, where .

Answers

Answer:

To calculate the force of impact F, first lets calculate the acceleration a of the ball:

a=v/t where v is the velocity of the ball and t is time

a=32/0.8=40 m/s²

To get the force F we need the Newtons second law:

F=m*a where m is the mass of the ball and a is the acceleration.

F=m*a= 0.2*40 = 8 N

So the impact force is F= 8 N.

Compare the chemical reaction that causes the Statue of Liberty to look green with the chemical reaction that causes a bike to rust.

Answers

Statue of Liberty - Is do to the sun which made the statue change color.

Bike rust - Is do to being exposed to moisture ( like Water, or any type or liquid.)

Hope this helps!!

Both the situations are examples of corrosion. The green colour seen in statue of Liberty is due to the copper oxide formation whereas the resulting in bike parts is due to the formation of iron oxide in the surface.

What is corrosion?

Corrosion is a chemical process by which the metals are destroying and change in colour. Metal surface when open to air or water will react with the oxygen forms corresponding oxides.

Corrosion is an electrochemical process where the oxygen acts as the anode and the metal surface cathode where the oxide deposits and the colour changes. Materials containing iron will react with oxygen forms a red iron oxide called rust which then completely corrode the metal.

Similarly, the statues are made of metal alloys containing copper. Copper also reacts with air or water forms the copper oxide which is green in colour that is why the statues are turning to a gree patchy colour over time.
