"Preparing Reports and Proposals - Research" Please respond to the following:

Locate a secondary source on EBSCOHost published in the past year that will help you explore the problem you have raised in your Justification Report. (Use the "Cite" tool on the EBSCOHost Website to copy and paste the APA Reference information into your response so that your classmates and instructor can see the source.) Next, explain why you chose this source, and determine how it will help you to evaluate your alternatives (i.e. possible solutions offered) and arrive at a recommendation for your employer.

Physical Science
Read the article titled "Aging US Power Grid Blacks Out More Than Any Other Developed Nation" under the Smart Grid terms section of the Science Corner. You can also view the article at https://www.ibtimes.com/aging-us-power-grid-blacks-out-more-any-other-developed-nation-1631086. Next, assess the efficiency of the current state of the national electric grid in the United States. Then, describe the key challenges in updating this grid to a so-called "smart grid".

Read the article titled "Earth's Inconstant Magnetic Field" under the Earth's Magnetic Field terms section of the Science Corner. You can also view the article at https://www.nasa.gov/vision/earth/lookingatearth/29dec_magneticfield.html. Next, summarize the main reasons why the researchers stated that "our planet's magnetic field is in a constant state of change". Then, discuss the overall manner in which a magnetic reversal might impact human activities on Earth. Include one (1) example of such impact to support your response.

Demonstrate an instance of static charge such as seen with examples #32 and 33 shown on page 209 of your textbook. Next, post a picture of your example then explain the method of charging you used as well as the charges displayed in each object.

The example is that of #32 and 33 is that one is charging by friction and discharging from pointed objects with a friend who stands at the far end of a carpeted room. Wearing your leather shoes, scuff your way across the rug until your noses ar close together. This can be a delightfully tingling experience, depending on the drynss of the air and how pointed your noses are.

#33 Briskly rub a comb against your hair or a woolen garment and then bring it near a small but smooth stream of running water. Is the stream of water charged? (Before you say yes, note the behavior of the stream when an opposite charge is brought nearby.)
