flag pole lab math 2018

In math, we had to find out how tall the pole with the Canadian flag in front of the school is using trigonometry. First, we measured from the ground to my partners eyes. We measured 1.53m. We stepped 3m away from the flagpole. Then, we used the clinometer to measure the angle from my partners eyes to the top of the flagpole. this created an imaginary triangle like this. We measured 62 degrees.

` 

Then we had to calculate it all using the equation x= 3 tan 62

This equals 5.64. Then we had to add the height from my partners eyes to the ground to 5.64. Our final answer was 7.17m.

During these past 2 classes, we have been testing static electricity. We had tried several different kinds of fabric (Cotton, silk, wool, fur, polyester, and plastic) and rubbed together with several different  (Aluminum, Lucite, Copper, glass, straw,wood, spoon, Ebonite)  and tested to see whether the rod would attract or repel the pith. The wool and Lucite were very attracted to each other. The Ebonite and polyester repelled a lot. Some things would attract, and then repel (animal fur and spoon, ebonite and plastic). The pith is neutral. When you use the example wool and lucite. When you rub the wool on the lucite, you’re creating a negative charge on the lucite because they are transfering electrons. All the electrons move to the back of the pith, and the protons move to the front. Then the protons (+) wants the electrons (-) from the lucite so they attract. After the pith collects all the electrons from the lucite, its now negatively charge so it repels other electrons. When something like fur is rubbed on ebonite, they create a similar charge, forcing each other to repel. Opposite attract, alike repel.

Digital Footprint

Your digital footprint can affect you in many ways. If you apply for a job, they are most likely going to look you up. If you are wanting to work at a daycare, and theres videos of yous aying innapropriate things, or doing innnapropriate things, do you really think you are going to be hired to work with kids. Pictures, videos, posts, etc. on the internet can be accessed by jImage result for phoneust about anyone. Just because you think its deleted doesnt mean it is. You could be denied by employers, colleges, etc. just for something that you posted 5 years ago that you thought was funny, but really wasnt.
