Most nonrenewable energy resources are burned for us to use their energy. Which of the following is a nonrenewable energy source
IrinaK [193]

Answer:

The correct answer is - A) nuclear.

Explanation:

Most of the non-renewable sources of energy are fossil fuels that are formed by the thermal decomposition of dead organic matter for million years and are converted to lighter hydrocarbons that contain high electrostatic potential energy.

Burning is the process that breaks the hydrocarbons into water vapor and CO2 with high amount of energy. Coal, natural gas and biofuels all three are fossil fuels and nuclear products are not fossil fuel but radioactive elements.

The amount of available energy changes between the trophic levels found in a food chain or energy pyramid. Photos (left to right
Aliun [14]

Answer;

A. leaf to mouse

Explanation;

-Considering the fact that the amount of energy at each trophic level reduces as it moves through an ecosystem from the lowest trophic level which happens to be producers (plants).  And about 10 percent of this  energy at any trophic level is transferred to the next level since the rest is lost largely through metabolic processes as heat.

-It means that the lower the trophic level the higher the energy obtained, for instance from producers to primary consumers, more energy is passed since it is the first passage of energy.

7. What is the kinetic energy of a 3-kilogram ball that is rolling at 2 meters per second?
nydimaria [60]
Kinetic energy = 0.5*M*V^2 

 Q7-
 
0.5*3*(2^2)= 6J

Q8a- 

0.5*2*(2^2)= 4J
0.5*4*(3^2)=18J 
the second ball has more kinetic energy.

Q8b-

at the max height, all the kinetic energy is converted to potential energy, 

gravitational potential energy is = M*g*h

that theory would apply if you wanted to work out the maximum height achieved if the balls were thrown upward by rearranging. But, we are simply working out which ball will have more potential energy so:

First ball:
2kg*9.81(g)*10m = 196.2J

Second ball
4kg*9.81*10m= 392.4J

The second ball has more potential energy

Which organisms are called the extremophiles and flourish in extreme conditions?
Fantom [35]

Answer:

Archaea

Explanation:

Most extremophiles are microorganisms (and a high proportion of these are archaea), but this group also includes eukaryotes such as protists (e.g., algae, fungi and protozoa) and multicellular organisms. Archaea is the main group to thrive in extreme environments.
