Please could you confirm the diameter and material of the wire as the Yield stress of copper wire of diameter 0.28mm would give a yield force of around 2N (200g mass added)
Thank you so much for your videos, they’ve really helped me understand all the practicals! A big thanks from me and all the students who watched your videos
Hello, I wanna choose one of these two methods for my chemistry ia (IBDP course) and I want to ask your opinion of which methods will be appropriate to obtain less uncertainty, accurate/precise so reasonable results. I personally think it would be the colorimeter method but then if I choose to use a colorimeter, I have to use software to see the absorbance because our school-provided colorimeter doesn't display the absorbance itself..so I wonder how do you think about these two methods/ which one will generate more accurate data
For ocr a Biology alevel practical 12 is a research practical what would you be doing, in terms of what is the research about and would they provide me with a topic to research and only then and there in the lab I’d be researching that specified topic? What is that practical about?
End of year practical soon, an hour from now to be exact 😂, and I could not for the life of me understand how the vernier scale works when I had my practise, I found this very useful, thank you!
until 2 min 24 seconds i swear she was looking the at some different camera or something only until this she looked at the main camera i am guessing Good video though
Thank you so much!! I've been searching for different videos to watch to annotate all my poems and these ones are absolutely perfect, they explore much deeper than we do in class and I've been able to write some really good notes due to these :)
I love this poem and the study of this event has been a passion of mine throughout my life. But the pedant in me must point out that the picture in the thumbnail is not from the Charge at all but the Charge of the Scots Greys from the Battle of Waterloo. Wrong battle and a regiment that wasn't present in the Charge.
