thank you

Great explanation Sophie.

Amazing video! Thank you!

Amazingly explained!

Great video apart from Tacoma, shared with my y13 class. Still useful as a discussion point: how is it like resonance.

en.wikipedia.org/wiki/Tacoma_Narrows_Bridge_(1940)

The bridge's collapse had a lasting effect on science and engineering. In many physics textbooks, the event is presented as an example of elementary forced mechanical resonance, but it was more complicated in reality; the bridge collapsed because moderate winds produced aeroelastic flutter that was self-exciting and unbounded: For any constant sustained wind speed above about 35 mph (56 km/h), the amplitude of the (torsional) flutter oscillation would continuously increase, with a negative damping factor, i.e., a reinforcing effect, opposite to damping.[3] The collapse boosted research into bridge aerodynamics-aeroelastics, which has influenced the designs of all later long-span bridges.

Great explanation Sophie.

Thank you

life saver

I didn't get the same answer for question a

Great explanation Sophie.

Very thorough explanation, this is just what I needed for my A Level! Thank you 😄I hope you are doing well

For part B could you also use F=ma? Since mass has increased, the deceleration has decreased ( a = F/m). Therefore stopping distance increases since s=v^2/2a (Rearranged suvat equation). Thanks.

The answer for part b should be 76.0 as you wrote the values of the refractive indexes to 2 significant figures but you should use the whole value given.

Why is there inert gases

Thanks this was really helpful!

thanks

I thought it needs quadrature of absolute (add/substract) or relative (multiply/divide) uncertainty. Would you please kindly help I can relieve my confusion here? Thank you in advance!

Great explanation Sophie.

Ty

thankyou !

Thank you someone that explains the phase difference!

You're back! - First view and thumbs up 😀👍

How do you find the absolute uncertainty when raising to a power because you only showed what is the overall percentage uncertainty not the absolute

Thankyou so much for this much explanation and solving problems 💖

Great work

published 1 day before recording it

Awesome video🔥 Please check and join our channel❤️ Let's enjoy football together😍

this was super helpful, thank you!

more useful than that 1 hour lesson in school

kinda cringe

Thank you so much for the explanation👍

thanks

i love u

Good job! No Calculus needed!

Nicely paced explanations and easy to follow. As others have commented, you did make a mistake at the very end of the video in arriving at 240 rather than 204 metres...Still very helpful

amazing video, cleared up everything, will you be making on A2 electric fields?

If I'm not mistaken the two main types of waves are mechanical waves and electromagnetic waves. transverse waves and longitudinal waves are just the types of mechanical waves

Also, what is the purpose of the calorimeter? Thank you!

So for this experiment there is no specific time limit that we must heat the solid for right? (As long as we time the experiment and the temperature changes?)

Keep it up

Good video and nice voice.

Thank you for the clear easy to follow examples. Well done. Hope to see more from you.

thank you
