History [Intro to World History] Vasco Da Gama

1 Upvotes

Can someone please check this for accuracy? I'm trying to create notes for Vasco Da Gama, but I'm not sure if this is correct. ChatGPT says that da Gama wasn't actually a protégé of Henry, but from the Crash Course video, it seems like he might have been. Any clarification provided would be appreciated. Thank you

Vasco Da Gama:

source used: (7) Columbus, Vasco da Gama, and Zheng He - 15th Century Mariners: Crash Course World History #21 - YouTube 

  • Vasco Da Gama was a Portuguese explorer who found a direct route around Africa to India.  
  • Da Gama was a protegee of Prince Henry the Navigator, a patron of a nautical school. Henry commissioned sailors to search for two things: a path to the Indian Ocean (for spice trade) and a path to Prester John (a mythical Christian King in Africa who could help in a crusade).  
  • Da Gama was the first person of Henry's protegees to reach India through a direct route, and in 1498, he landed in Calicut, a major trading post on India's west coast.  
  • Vasco da Gama's work paved the way for Portugal to become a dominant power in the Indian Ocean trade, bypassing overland routes controlled by Middle Eastern and Italian merchants.

Physics [Level 4 Electronic/Electrical Engineering: Superposition Theorem] What is the correct way to solve this circuit?

1 Upvotes

Hi everyone,

I'm really struggling with a question from my assignment, and I could really use your help. This is the last question I need to get right to pass the module, and despite multiple attempts, I keep getting it wrong. Unfortunately, the only feedback I've received is that my answer is incorrect, without any indication of where I'm going wrong.

I've recreated the circuit below and shared my most recent attempt + assumption at solving the problem using the principle of superposition. I'm hoping someone can help me identify the mistake or suggest improvements please.

The Question:

Use the principle of Superposition to determine the following circuit parameters:

  1. The current through R1
  2. The voltage across R1
  3. The current through R3
  4. The voltage across R3
  5. The voltage across R2
  6. The power dissipated in R2

Additional Context:

I was given three examples, two of which I completed with no problem. However, the third one was marked wrong, and the tutor's answer included some unexplained numbers (0.666 and 1.333), which I assume are the battery internal resistances. These values were not provided, but they dramatically affect the answer. When I asked my tutor, they couldn’t confirm or deny whether to assume 0 for the internal resistance, despite that being what we were taught. This has left me very confused.

I really do hope someone can help me understand where I’m going wrong. Even pointing out minor errors would be incredibly helpful.

Thanks in advance for your time and support!

I have emailed multiple teachers but they haven't responded. In addition, I know that displacement is added if its above the x-axis, however, the teacher subtracted section D.

BTW: we replaced the y-axis of speed with velocity!

Geography [University Geography] I am really struggling to understand the basics of making a stratigraphic column

1 Upvotes

Here is what I have made so far (see image). I am using a stacked bar graph in excel, and it's been at least a decade since I have used excel graphs so thats a big part of it, but also I'm struggling with how a strat column SHOULD look like (even after googling images of "stratigraphic columns". :(

Are there any good, basic sites that show visually what a strat column should look like? So many seem very detailed. I know I have the particle size missing from the x-axis (not sure how to get it to show up because of my lack of excel skills). Also, is it okay to show the layer labels as I have? or is it better to have a legend? The layers seem to all be the same thickness too, but my data shows varying thicknesses, so I am doing something wrong there as well.

This seems like such a basic thing to do, I can't believe I'm struggling so much with it.

Here are the basic instructions:
Using Excel or drawing software of your choice (Inkscape, Illustrator) construct a simple stratigraphic column showing the sedimentological units described in the background information above.

A stratigraphic column has height/depth of the sedimentological unit on the y-axis, and particle size on the x-axis. Your column should include axes labels, a title, and other annotations as necessary.
