My school force me to watch this and make Questions!😭

i love you

He coverd everything in 5min😮😮

So crispy. Subscription done Sir. Am a Tutor turned QC Chemist and takes classes upto plus two students. You did a smooth job. Exam notes nearly. Awaiting the next

@cognito your playlists of all sciences and maths are extremely helpful however im wondering if maybe you can separate the playlists into unit 1/year 10 and unit 2/year 11 if you cant its fine.

Awesome teaching 👍👍👍👍👍

When you say edexcel triple and higher does that mean combined science higher + triple or higher triple science only?

It was not that simple in class

Thank you so much

Best channel, i have my physics exam tomo, wish me luck

That was the best explanation I have ever seen in my whole life. I feel like no other teacher can explain this as good as you! I'm so glad I found a vidoe like this! Thanks so much

dope

This helped A LOT thank you

No one can hear you scream in space.

Shut up

Hmm i feel like u should start a website

do we have to know about the fluid in the cochlea?

I do feel like this is more KS3-KS4 but this was a really good explanation!

i have my final physics text in 30 mins and i need to learn this

I love the way you explain everything, physics is soooo much simpler now thank you so much

If you only would upload a video about echo and sound at different temperatures then it would've cover up my whole chapter:']

Thank you so much for this explanation. 5 minutes of this video covered a lot of lessons at my school. Thank you

Best channel ever
All physics here

Simple, accurate and helpful. Love it🤙🏽🤙🏽

Thx I passed my exam

Hi bud, would you be able to explain how sound is absorbed by materials please?

Explain Doppler Effect. Facing problems understanding that.

When are you making a video on Doppler effect? The way you explain is seriously getting me addicted to this channel while exams are coming up 😁😋

Thank you so much this helps a lot!!!

What happens if you put bloggers into your eardrum will it effect your eardrum or should it be fine?

frequency decreases when wavelenghth increases

Which medium does sound travel the farthest ?

time to get ahead of my class hehe! >:)

im being forced to watch this by my teacher im in y7

What is the speed of sound in air

this made a lot more sense than my teacher explained it oh btw I passed my exam because of this

I HATE HONEY SO WHY ARE YOU SPONSERED BY HONEY

Your videos have been very helpful to me at home and while studying

Perfect - brilliant

I swear this is the easiest explanation I've seen in my whole educational career.

babatunde is here for a science lesson on teams

sino dito yung mga nanood kasi kailangan nila sa science hello same tayo:>

Thank you

Why frequency remain constant I wonder?

U deserve appreciation... Since u just concise book of oceans into a drop of water that works... Hoping soon ur website establishment..i will be first to drop there.. 😊
