heya!!! i know you probably wont see this but i just finished my year 10 mocks for science, and because of YOU, was able to get 9 9 9: 85% biology, 95% physics and 99% chemistry. honestly wouldve gotten 7s if it wasnt for you!!! LOVE YOU SO MUCH!!!
how would you "describe the difference between a linear and non-linear relationship between force and extension" in an exam (from the current GCSE PHYSICSC spec)
So, what would a FULL answer for "Explain why more than one force is required to stretch this band" WOULD IT BE: Makes the forces unbalances, causing band to move?
3:37 The bromine molecule reacts here with a radical but then he says at 4:18 it won't take part in the reaction as a bromine molecule? Does it mean it can still happen just only if there are free radicals?
Thank you. I just reviewed this anyway online and I believe I have a good understanding. But my source of study can sometimes be understating and it's good to check with someone whom has as much experience as you. Edit: Yep, now I understand it even better, thanks chief.
i dont get the reactivity because the reason reactivity decreases for halogens is the same reason reactivity increases for alkali metals so why would reactivity decrease for halogens if that made sense??
hi sir, love your videos!! I just wanted to know when you will complete the videos for the A-level Chemistry content (year 13). Many thanks for everything you do <3
I'm really confused on this part: If we increase the light intensity and the rate of photosynthesis is increasing it tells us light intensity was the limiting. Could you please explain? How is it limiting if it's causing the rate of photosynthesis to increase? Thank you :)
When we increase light intensity, if the rate of photosynthesis increases then that tells us that the plant could have used a greater light intensity. In other words, light intensity was holding the rate of photosynthesis back ie it was limiting.
Hello sir, Are you going to upload the rest of the year 2 modules as well? Please do it, The only reason I got through year 1 chemistry was your videos, they were very helpful. Don't know what will I do without your videos, Please upload the rest of the modules as well. PLEASE!!!
Charge is simply a property of certain particles eg electrons have a negative charge. If we have 10 electrons then we have 10 negative charges. The total charge is measured in coulombs. Current is a measure of how much charge is flowing in a second eg 1 ampere = 1 coulomb of charge flowing in 1 second.
Hi Sir, this is my last time watching any of your videos as I will be doing a level physics which you unfortunately do not do :(. However, from Yr9 till Yr11, you have helped me so much that I was so confident in science that I stopped going to tutors because you explained everything perfectly. I recommended your channel to many of my friends who have recommended it to others - you have blessed us all! No matter what grade I get in science in August, I will always be grateful for your work, thank you sir.
My chemistry mock is at 9am tomorrow… on my practice paper I got a 7 because I knew nothing on bonding from my teacher teaching it in confusing ways… I hope that I can make it to a grade 8 or even 9 because bonding is where I lost ALL my marks, but now I won’t, all thanks to you!! Thank you for making it easy to understand!! ❤
