Fossil Fuels versus Renewable Energy

Assignment 1: Discussion—Fossil Fuels versus Renewable Energy
In physics, energy is defined as the ability to do work. When most people think of energy, they think of electricity. The energy that is used to produce electricity is derived from a number of resources. Much of the energy used today is obtained from fossil fuels. However, these resources are limited. As a result, alternative and renewable resources are being explored for production of electricity.
Using the readings for this module, the Argosy University online library resources, and the Internet, respond to the following:
  • Discuss the scientific and technical concepts related to the uses of fossil fuels and renewable energy resources.
    • Consider how fossil fuels such as coal, oil, and natural gas are utilized for production of electricity.
    • Consider how alternative and renewable resources such as wind turbines, hydroelectric power, wave power, and geothermal energy are utilized to either produce electrical energy or provide an alternative to electricity consumption.
  • Explain the advantages and disadvantages related to both fossil fuels and renewable energy resources such as wind power, hydroelectricity, geothermal energy, and biomass.
    • Consider issues such as availability of the resource, sustainability of the technology, and environmental impact.
  • Provide 2–3 examples of the uses of both types of energy resources that are utilized in your community.

* (For improved memory and increased awareness, remember the mnemonic, GARREACS.)
  • Gender
  • Age
  • Race
  • Religion
  • Ethnicity
  • Ability
  • Class
  • Sexual Orientation
Once you have chosen one aspect of cultural diversity to study in depth, prepare a Research Paper with the following components:
  1. Summarize the pertinent historical, political, social, economic and cultural factors related to your chosen aspect of diversity.
  2. Consider and summarize any relevant developmental theory models related to your chosen aspect of diversity.
  3. In regard to your chosen aspect of diversity, identify the relevant laws or programs that have either helped or restricted access to care and support.
  4. Evaluate how your chosen aspect of diversity, in combination with two other aspects of diversity, can lead to increased needs or issues. For example, if someone is female, African American, and lesbian, will there be additional challenges? Select any combination of three aspects of diversity to discuss.
  5. Describe at least two resources currently available in your area for someone needing special services related to your chosen aspect of diversity.
  6. Explain how your personal characteristics will either complement or conflict with this diversity issue. Consider your own biases and prejudices or those of your family of origin.
  7. Discuss relevant concerns, cautions or insights necessary for you to be a culturally competent human service professional.
  8. Must document all sources in APA style, as outlined in the Ashford Writing Center.

Vibrations, Waves, and Sound


Please solve the following problems. You must show all work.

1. A spring with negligible mass stretches 34.0 cm when a 144 g gram mass is suspended from it. Now I suspend a mass m from the spring. If it oscillates at an angular frequency of 4.51 rad/s, what is the mass?

2. A 3.45 kg mass vertically compresses a spring 67.0 cm before it starts to rebound. How high will the Mass move above the uncompressed it the mass is left to “bounce” back up?

3. A transverse traveling wave on a cord is represented by D = 0.25 sin (6.8x + 28t) where D and x are in meters and t is in seconds.
a) Determine the wavelength of this wave.
b) Determine the frequency of this wave.
c) Determine the speed of this wave.
d) Determine the amplitude of this wave.

f) Determine maximum and minimum speeds of particles of the cord.
4. A person is watching water waves at the ocean and they notice the peak to peak distance between the waves is 3.4 m. They also notice there are 55 waves every 10.0 seconds passing the end of a pier. How fast are the waves going?

5. A whale sends an undersea signal to its mate and then gets a response 4.5 seconds later. How far away is the whale’s mate?

6. A person sees a distant lightning strike, then 4.5 seconds later he hears the thunder clap. If it is 35 degrees Celsius, how far away was the lightning strike?

7. A single bass amplifier produces a volume of 102 dB. What is the sound level if a guitar amplifier what produces 98 dB is played at the same time?

8. A string on a guitar vibrates at 420 Hz. If the tension on the string is 102 N, what is the mass of the string if the portion that vibrates is 63.7 cm long? 


Notes on Week 6 Homework:

In number 2, assume the mass is release directly above the unstretched spring. The question should give you a pretty simple answer because it doesn't tell you a  height above the spring. Using the conservation of energy, you should find that the mass doesn't even matter. 

Part f of number 3 is asking for "speeds" which only refers to the magnitude of the speeds. There shouldn't be any negative answers.

Remember sound travels at different speeds through different materials.


Sound in water for example does not travel at the same speed as water in air.

Other than that, I'll just remind you an important hint. Decibels are a logarithmic scale. They do not add together like normal numbers. They're a made up scale with an arbitrary zero point so you can't do real math with them unless you use what you know about mathematics for logarithmic functions.
