Assignment: Energy for the Future Exploration

Use data from the past to make a prediction about future coal production. When making a prediction, look for trends in the data and use other information to support your prediction.


Coal Production Table
United States Coal Production by Region, 1995–2011 (in million short tons)

Year Appalachian Interior Western
1996 452 173 439
1997 468 171 451
1998 460 168 489
1999 426 163 512
2000 421 145 510
2001 431 147 548
2002 396 147 550
2003 376 146 549
2004 390 146 575
2005 397 150 585
2006 391 151 619
2007 378 147 621
2008 390 147 634

2010 335 156 592
2011 336 170 588


Study the Coal Production Table and find out which region of the United States produced the most coal in 1996 and which region produced the most coal in 2011. Write your answers here.

1996:


2011:




Graph (see next page for graph paper grid)
Using the data from the Coal Production Table, create a graph of coal usage in each region over the years. The x-axis should be years, and the y-axis should be coal production. Use a different symbol or color to represent each region. Remember to include titles and labels.

Scan or take a picture of your graph and submit it with your assignment.


Analysis
Changes over time are called trends. You can see on the graph a downward trend in the Appalachian and Interior regions and an upward trend in the Western region.

Try predicting future coal production. Using a ruler, draw the lines for each region. Go beyond 2011. Draw the line with the same pattern it follows on the graph. The extension of the lines is based on what you predict will happen with coal production.


Questions
1. How much coal will be produced in the year 2020 for each region?






2. What trend would you predict for the next ten years for each region?






3. If people keep using coal in the same way, scientists say there may be enough coal reserves to last 200 to 300 years. Does your graph show trends that match what scientists say? What kinds of factors might cause them not to match?






4. Can you think of any problems that could come from using only 15 years of data to predict trends for the next 100 years? Explain your answer. How could you prevent some of these problems?

A student conducts an investigation to study the impact of solar energy on land and water surfaces. He places a cup of soil and a beaker filled with water of the same mass on a plastic tray beside a window. After 10 minutes, he measures that the temperature of the water in the beaker is lower than the temperature of the soil. He places the plastic tray in the shade of a tree, and after another 10 minutes, he measures that the temperature of the water in the beaker is higher than the temperature of the soil.

What can the student conclude from his investigation?

Lucia is playing with magnetic toy vehicles. She has two identical toy vehicles (purple and pink) that start on opposite sides of a center magnet that cannot move. She moves both vehicles one space closer to the center magnet Please explain what would happen if Lucia released hold on the two magnet cars. How do you know?

Answers

Answer:

They would connect

Explanation:

The cars are magnetic

Answer:

The potential energy of both toy vehicles, purple and pink, increased. The potential energy of the two vehicles increased because they were moved against the magnatic forces. The potential energy of the pink car increased more then the potential energy of the purple car because the pink car was closer to the center magnet. Since the pink toy was moved closer to the magnet, it will have more potential energy because of the short distance between it and the centre magnet. As we know, potential energy does not increase linearly. Meaning when because the pink magnet is closer to the centre magnet than the purple it will have a greater potential energy increase than the purple. The purple toy as well is now closer to the magnet and will have a potential energy change, but not as large as the pink's change.

A topographic map helps architects to find the elevation of a  building site. Plant roots hold the soil in place and helps prevent erosion. The  term deposition is used means laying down of sediments.

Satellite views help scientists they give scientists the ability to predict catastrophic events.

What is topographic maps?

A topographic map depicts the geographical features of the region. They might make use of them to make sure their designs are on the proper road. It shows the elevation of a building site. Thus option D is correct.

Soil erosion is the process of flowing of soil with water during heavy rains or floods. Plant roots are strongly adhered and they strongly holds the soil under roots. They helps prevent erosion.

The term deposition means the laying down of sediments. Rock sediments sands, and other minerals undergo sedimentation.

Satellite views helps scientists  the ability to predict catastrophic events. Satellites study changes occurring around planet and forecast the presence of extra terrestrial objects and their movements.

I have two questions
1. "Explain the relationship between amplitude and energy"

2."Explain the relationship between frequency and energy"

Answers

Answer:

1)The energy transported by a wave is directly proportional to the square of the amplitude. So whatever change occurs in the amplitude, the square of that effect impacts the energy. This means that a doubling of the amplitude results in a quadrupling of the energy

2)Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy.

Explanation:

The correct answer to the question is : C) A pendulum swings back and forth.
EXPLANATION:
Before answering this question, first we have to understand the law of conservation of energy.
As per law of conservation of energy, energy can neither be created not be destroyed. It can only change from one form to another form, and the total energy of the universe is always constant.
As per the question, we have a pendulum which is moving back and forth.
Let us consider a pendulum which is taken to some height from its equilibrium or mean point. The energy possessed by the pendulum at this height is gravitational potential energy. When the pendulum is released, the potential energy is converted into kinetic energy. At mean point, whole of its potential energy is converted into kinetic energy.
Due to inertia, the pendulum reaches at the other extreme point. During its movement from mean point to extreme point, the kinetic energy is converted into potential energy. At extreme point, whole of its kinetic energy must have converted into potential energy. The same process will be repeated.
Hence, it obeys law of conservation of energy.
Hence, swinging of pendulum back and forth is the best example to demonstrate the law of conservation of energy.

Consider these scenarios.

Scenario 1- Your ear is resting on the end of a metal bar that is stuck by a drumstick about 7 meters away from your ear.

Scenario 2- You are about 7 meters away from a metal bar that is struck with a drumstick. The sound travels through the air to your ear.

In which of these scenarios would the sound of the drumstick hitting the metal bar get to you in the least amount of time? Explain your answer.

Answers

Answer:

The sound of the drumstick hitting the metal bar will get to me in a shorter amount of time in Scenario 1. The sound wave will travel faster in the metal bar than through the air because the speed of sound waves in solids is faster than it is in gases.

Explanation:

The sound will reach my ear in a shorter time in Scenario 1 because sound travels faster through the metal bar than through the air. The speed of sound waves in solids is faster than it is in gases.
