I just want to say that I had a test in one week and I did zero revision and I didn’t know how to but then I saw this guys channel and I got full marks on the test, I genuinely want to say that this guy puts so much effort in his videos and these really help.

[@cazoxv5006]

You are saving my GCSE's right now! Thank you so much!

[@Jek_nintendo]

Glad I have notations on ! Got an A* in physics today aswell 😂

[@APower2004]

how cool

[@user-dn3mg8pm4z]

any advice ? I'm doing A level Physics

[@itzmejoe256]

well done dude

Someone remind me to come back so i can let u guys know my physics results when i get them 😭😭 goodluck to everyone doing physics tmr!! Last paper guys, do ur best and don't give up 👍

[@jbpivl5142]

Best be a nice paper

[@HiMeee993]

Got a 6!!😭 better than i expected cuz i only started doing higher tier sciences a month before gcses started😭😭

[@hamzamuhmmad7191]

dang gonna do mine next month. hopefully i do good lol

[@HiMeee993]

@@hamzamuhmmad7191 try teaching the topic your revising to someone younger, if they understand it well from you it shows u learned the topic properly and know what ur talking ab.

[@karynpritchard4172]

This video is awesome, I am only in Year 8 but this explanation has helped me a load. Thank you.

[@Ahltyyy]

word of advice, learning your gcse content earlier would help you so much

[@Noor-ib5hf]

@@Ahltyyy i wish i did that too. i regret 'going with the flow'. i wish i had bought all my textbooks beforehand and watched all of these amazing channels before starting my real gcses.

[@RNAANA]

this guy is underrated

[@keirarachel9102]

tell me abt it, he's videos are so damn helpful

[@MayoYaban]

ok, this is super helpful and all.. but who cooks their apple 🍎

[@vintxge_taetae]

😭💀

[@er0driguez584]

Great video. Thanks. (:

[@creativeaaditya2436]

3:17, what kind of a psychopath heats an apple!

[@stardewsimmer6638]

baked apple and custard is actually really nice

[@bengoody595]

Regarding Microwaves, are the smaller amplitude microwaves the ones that are absorbed by water and the larger amplitude waves the ones used for communication?

[@miapatel8025]

Idk

[@nicholasmitchiner8630]

just wondering. Will you do a series on the astronomy GSCE content or not?

[@Lightningod7]

Thanks, it helped me alot:)

[@abdmations]

I understood everything except why would anyone put there apple in a microwave

[@vintxge_taetae]

Bro💀💀😂😂

[@AmenaAhson]

Now I can pass my test which is tomorrow thanks a lot sir.

[@Noor-ib5hf]

Hello! will you be making a level physics content too, for example a level physics qs by topic, just like you've done for biology and chem a level? thanks!

[@mamiyachy113]

Thanks sir.

Great graphics. (:

[@Loagun]

Great channel. But all satellite TV antennas are stationed on the ground just like radio and cellphone towers. In fact a lot of times radio, cellphone, and satellite tv antennas can be seen sharing the same physical tower structure, just placed at different heights and directions to prevent interference. :)

[@Cognitoedu]

Heya, exactly! The satellites themselves are in orbit around the earth though, and they relay the signal to the antennas on the ground as you say :)

[@Loagun]

@@Cognitoedu but they don't. That's not even factual. Thats in movies.

[@emilylane1229]

@@Loagun I can't believe you actually think that 😂

[@philipbrady7635]

videos are amazing

[@realityaspirations8491]

So basically microwaves must be causing infrared radiation to be produced from the food. as heat is infrared

[@AGuy-vq9qp]

No? Heat produces infrared.

[@ImBobtheHampter]

I like all the videos I watch, subscribe and also share with my friends

[@ImBobtheHampter]

And the information in your video are very useful

[@Wojbest_YT]

@Cognitoedu 2:23 could you confirm no one got burnt in the production of this video😂

[@user-lx4qz7nn7w]

Interesting!!

[@EldanaGirma-tm9zp]

Why do u use "by" why don't u say absorb a water molecules

[@salmaazzzam7485]

in AQA should we know this for the foundation paper or only the uses of each wave

[@josephdurston6680]

I got a A** cos I'm such a freaking smart boy.
