Hi
Hi ur lessons are so interesting my be ur friend
Thank you soo much ! This helped a lott <3
♥️♥️♥️
Great Video. Thx
Its nice thank you
Thank uu ms Hoo ...life saver
You're welcome 😊
I have created an updated video with clear audio and more detailed explanations, as well as more examples on different thermometers and how to solve those questions! Watch it at czcams.com/video/r5WCIeaTJX0/video.html
Simple and clear explanation 🎉
I'm glad to know this video has helped you!
7:58 where is the video about total internal reflection
You have the best explanation but the sound quality is 😢
My apologies for that! I will try to redo this topic with better audio quality soon.
Very helpful for my upcoming exams
Good to know that this was helpful for you!
thank you ms Hoo!! got physics exam tomorrow
You're welcome! Hope you did well in the exam!
Very helpful video thank you teacher
You're welcome! Glad you found it helpful
0^2 is 1
0^2 = 0x0 = 0 It is 2^0 that is equal to 1. You can check with your calculator :)
Nice so helpful lolol
Glad you found it helpful!
Thank you so much Ms Hoo for explaining so well and taking your time to post this topic it's very helpful ❤
You are so welcome! I'm glad to hear that you found this video helpful. All the best for your studies.
I've bee watching ms videos for a quick revision and I found that ms explanation is easy to understand, I feel motivated when studying thank you ☺️
Glad it was helpful! It makes me happy and inspired to know that students find my videos easy to understand, I am doing my best to make educational videos to help students. Happy studying and all the best for your exams!
Wow I just discovered this channel that its honestly SOO underrated! I love how much effort u out into explaining each questions! Love this video ❤
Thank you so much!! I appreciate your comment, and it makes me happy to know viewers like yourself find them useful. It keeps me motivated to share more. I really do try to share as much as I can for the students' benefit. I will try to share more PYQ explanations, so far I only managed to do this one paper because I take so much time to explain. If you have any requests, do ask, I will do my best to accommodate!
@@PhysicsRoxz yesss keep posting!! I know one day ur effort will be appreciated by more people 🙌🏽 keep up the good work 💕
Thank you for the time and energy you put into your channel 🙏🏼
You're welcome! I appreciate your comment 😊
thank you ma'am you really helped me
You're welcome! Glad to hear that!
Thanks mam😊❤
Most welcome 😊
amazing video! i understood clearly, thank you!
You're welcome! I'm glad to know that it helped you understand this experiment. ☺️
@@PhysicsRoxz omg whatttt the exact triangle experiment came as one of the questions in my igcse physics (paper 61) 😁 (may/june 2024)
@@ohemaa345 Oh really!!! I hoped that this video helped you in answering those questions!! Was the paper overall challenging to answer?
@@PhysicsRoxz hmmm, it wasn't too bad in my opinion!
That's good to hear. I'm sure you did well! All the best for your other papers 💪🏻
i appreciate you so much teacher, i appreciate that u keep uploading even when sometimes the views you get don't do u justice ❤
I appreciate that! I'm doing my best to share knowledge so that students can do well in their exams. The views aren't very high but as long as my lessons help the few students who find them helpful! Thank you for the thoughtful words, it really made my day. All the best for your exams 💪🏻
That’s really helpful! Thank you so much, miss! Btw, could you plz upload chapter 4 as well😊?
You're welcome! I will do my best to get it done this weekend. I was hoping to do all 6 chapters but not sure I can get them all ready before the exams, it has been a very busy week! I'll just try to do Chapter 4.
@@PhysicsRoxz Ohhh THANKS A LOTTT🌹🌹🌹
Thank you so much! This helped a lot!
You're welcome! I'm glad to know this was helpful :)
Thanks miss
You're welcome
If the ray came from the middle of the upper semicircle, will the ray remain the same and the path will not deviate?
Yes. In that case, at both boundaries (air to glass, glass to air), the incident angle is zero and refracted angle is zero. So the path of the light ray would be in a straight line with no deviation.
Nice it is so helpful for me ❤❤❤❤❤❤
Glad to hear that!
this was helpful thank you. but how can i do this experiment but with using a slide potentiometer?
Using a slide potentiometer will be a different experiment studying different variables. The slide potentiometer is used to change the voltage or current of the circuit, but cannot be used to change the length of the wire. So it cannot be used in this particular circuit; it would be in a different type of circuit to investigate different variables.
Nice video
Thank you
🔥🔥🔥🔥🔥
thankyou soo much
Most welcome 😊
Mam I have send you the pdf have you got?
Hello, sorry for my late reply as we were on holiday last week for Raya & Easter. I have received the PDF, but unfortunately I don't think I will be able to help as I am not able to speak Hindi. All the best though!
Mam can you teach English for class 8- (English literature) book name is Ferns MCB.
Hello! Unfortunately I don't have the book so I won't be able to go through it.
Mam can I send you the chapter pdf, then you can make the videos send me your Gmail I'd, mam make this chapter video when you are free, actually we are friends, we watch your physics experiment video that are very awesome and your teaching is mind blowing😊.
Sure, please send to me at physicsrox.com@gmail.com. However, I cannot guarantee that I will be able to make the video because it depends on the content! I will need to take a look first.
Mam have you got my message in your gmail ?
No, I haven't received it. Can you try to resend? Please note that it is physicsrox.com@gmail (there is .com at the end, not just physicsrox)
Thanks for sharing with the folks who haven't seen one of these meters Ms. Hoo!
You're welcome! That's what I hope to share more on my CZcams - video of various lab apparatus!
miss your videos are fantasitic keep making those ! i would like if you woul dmake a video where you solve past papers regarding those topics thank you stay safe
Thank you! I have actually considered making videos just like those, but I wasn't sure if they are what people are looking for. May I know which syllabus you are taking? SPM, IGCSE, EdExcel, or another? I will see if I can start making them this week.
@@PhysicsRoxz igcse miss
Noted, I will start sharing PYQ discussions on selected topics for IGCSE starting this weekend. Thank you for your feedback!
@@PhysicsRoxz okay miss!
I enjoyed the video, thank you for taking the time to produce and post it. Cheers from Iron Rock, Pictou County, Nova Scotia. Canada. population about 5!, but proud. HAHA
Glad you enjoyed it! Thank you for writing. I'm tickled to read your comment. Is the population 5... or 5! ? Math joke... 5! = 5x4x3x2x1 = 120 😁 How is Nova Scotia?
Well done
