Hello Professor Wasson and Class,

"Pressure, Temperature, Electricity, and Magnetism" Please respond to the following:

Our grids are losing power every day and within the past two decades. It was once estimated the between the 50’s to 80’s. There is only two to five weather conditions in that time period that protest to our power outages. Now we are getting superstorms that account to an increase 70-130% from 17-21% in the pasted. Our planet is getting hotter using resources at an increase rate. Therefore, our grids are in more than ever.

We have politicians that can’t come together on a federal and state policies. Our infrastructure-girds are outdated. And most important coming up with money to finance the costs of newer girds or other resources is a daunting task.  Smart grid means “computerizing” the electric utility grid” (DOE, 2015, par., 4) to create a network-digital in detecting or react to changes in grids, would be costly. Getting wind farms to a consumer’s home, is also challenging using computer technologies.

The inner core that is consistently spinning inside much faster than the earth, is hot like the surface of the sun, and has a second ocean layer that is called, “the outer core” that is made of liquid or the magnetic field comes from this source.

When something has static charge, we know that that charge could be either positive or negative but not both. When we think of magnetic fields, we see that positive attracts to negative and vis, versa. This magnetic field in the outer core constantly covers the inner. We do know that once heat is applied it expands around the inner core. For example, and used in the article, if you heat a pan, the liquid in it will steer in it. Since the earth is constant rotation, the liquid moves like hurricane or whirl pool and it constant motion. This accounts for the dynamo effect.

This could change the earth’s geographic outcome such as our north pole could be in Africa and south pole could in Canada. I think this is right. This could impact using GPS unless update?

  • Demonstrate an instance of static charge such as seen with examples #31 or 32 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.

 

Static

 

 

 

It could be a balloon on top of someone hair making static. Rubbing a balloon on carpet will give it some electrical charge not moving and is built up in that area or on the surface. Our bodies also give off this static-energy. We both could give off positive or negative static.
