3. The electric (E) and magnetic (H) field vectors in a medium are given by
𝑬 = 𝒊^ 20𝑐𝑜𝑠(𝜔𝑡 + 𝜋𝑦)𝑉/𝑚 , 𝑯 = 𝒌^ 20 𝑐𝑜𝑠(𝜔𝑡 + 𝜋𝑦)𝐴/𝑚
𝜂
Use Maxwell’s equations to determine η and ω. Assuming that for the medium 𝜀 = 36𝜀𝑜 ,
𝜇 = 𝜇𝑜 .
( PLEASE DO THIS IT WILL MEAN SO MUCH TO ME THANK YOU! :) Choose one of the following psychology theorists and build a résumé to fit his theories and career achievements, which are covered in the unit. Include the following in the résumé:
- Three important pieces of information about the psychologist's theories
- One or two important experiments
- An explanation of how this psychologist changed psychology
Make sure to write the résumé in the first person. Be sure to use your own words to explain the points you include. After you complete your résumé, write a three- to five-sentence paragraph explaining why you included the things you did on the résumé. Use the rubric to guide your work.

A friend of yours reached out for help. They have a sibling in grade 9 that has to complete an assignment in Life orientation on African moral theory and after doing research they are unsure if they understood this theory correctly. Since you have recently studied African moral theory as part of your Business ethics module, your friend has asked you to briefly explain (not exceeding 300 words) this theory to their younger sibling.
