Don't skip ads guys...he gets paid if we play out the ads. Honestly, it's the least we can do for such great quality videos. Thank you for such amazing work!
Your videos are INCREDIBLE! One thing - at 19:35 when you set up the equation you use 300m/s instead of 343 m/s for the velocity of sound. So the answer should be closer to 1000 Hz unless I'm missing something.
I love your videos and find them extremely helpful! Thank you so much but I had a quick question: for the practice questions shouldnt we use 340 m/s as velocity of sound? In 22:40 you used 300 m/s?
FIRST off your da man! but secondly i found a way to help make the plus and minus signs more easy if you decide to redo the video. its called the TATA method where the numerator has +/- and denominator has -/+ so it should look like (+/- / -/+). for top and bottom, then say TATA! for Towards or Away. for numerator + is towards and - is away. Denominator - is towards and + is away. Thank you again for being very helpful!
Love your videos! Just wanted to say that at around 24 minutes, you have 343 + 100 m/s in the numerator but your diagram shows Vd as 150 m/s. Otherwise, great content and keep it coming!
The layers being pulled up throughout the video is kind of distracting. I did enjoy the real-time sketching to illustrate points. Thanks for making the video.
on the last example, Vo=150 m/s and you put V0=100 m/s in the f' equation and ended up with f'=2254.5 Hz instead of what I got. Is there a reason for that?
ultrasound machines create sound waves.. those sound waves bounce off its target.. then the sound waves go back to the ultrasound machine which detects how the sound waves have changed.. based on how the sound waves have changed once reflecting off its target object, the machine can infer the velocity of the object..
Unfortunately I’m studying for medical school so I do not have the time... do you have a specific question I’m happy to do what I can to help occasional specific questions
The most important component of studying for C/P is practice problems... without a doubt that section specifically is practice problems... and I’d focus a little more on chem than physics because word in the streets is that new MCAT has very little physics..
@@sciencesimplified3890 Yes I'm thinking I should just do much more practice. I don't have specific questions right now but if some come up I'll lyk. Do you mind telling me what a good strategy for BB is in comparison?
