Alysha wants to test the effect of different materials on the melting rate of ice. She finds the initial mass of four pieces of
Tanzania [10]

Answer:

In the experiment conducted by Alisha to test the effect of different materials on the melting rate of ice, the dependent variable is the mass of the ice, and the independent variable is the type of cover material.

Explanation:

During an investigation or experiment, the dependent variable is the one whose changes will be studied, while the independent variable is able to influence the changes of the dependent variable.

In the case where it is wanted to <u>measure how different cover materials affect the rate of ice melting</u>, the dependent variable is the mass of ice and the independent variable is the coverage material, capable of affecting the time it takes for the ice to melt.

What do many scientists believe about the purpose for asteroids.
katovenus [111]

Answer:

Various scientists describe asteroids in different ways:

  • Some scientists consider it to be rocks which orbit around the sun.
  • Other consider it to be small planets.

The majority of the scientists agree that asteroids might have come into existence at the time of solar formation. The parts which broke down during the formation of the solar system resulted in the formation of asteroids.

<u><em>Scientists believe that asteroids might not have a major function in the universe but studying them would be of great benefit. This is because as they are parts broken from the solar system, exploring them will let us know about some unknown features of the other solar system bodies. </em></u>

Many scientists worry that the influence humans have on the biogeochemical and hydrologic cycles will cause lasting damage to Ea
melisa1 [442]

Answer:

Driving a car, smoking, burning of woods for heating purpose and cooking food.

Explanation:

Driving a car, smoking, burning of woods for heating purpose and cooking food are the activities that are performed in our home daily. These activities greatly affected the biogeochemical and hydrologic cycles by increasing the concentration of carbondioxide gas in the atmosphere. Burning of fossil fuels in the car engine and burning of woods releases carbondioxide gas that causes air pollution. The use of electric cars and electric heater can decrease the impact on these biogeochemical and hydrologic cycles.

The tendency for energy to be lost as heat during the transformation of organic matter is support for what concept?
leonid [27]

Answer:

a. Entropy

Explanation:

Entropy is the measure of the degree of disorder of a system, being a measure of the unavailability of energy. Rudolf Clausius was the first to use the term Entropy in 1865. Entropy would be the measure of the amount of thermal energy that cannot be reversed into mechanical energy (cannot perform work) at a given temperature.

Because of this concept, we can understand that the tendency of energy to be lost as heat during the transformation of organic matter supports the concept of entropy.
