Very good video! You should be rewarded

@danthetutor2624 6 ай бұрын

Thanks, but the reward is the smiles on my students’ faces. And money. I also like money.

When you are moving away from the bear are you not suppose to add

@danthetutor2624 8 ай бұрын

Well that depends, are you the observer or the source? The bear is the source and you're the observer, and you're running away from the bear. So therefore, it should be minus in the numerator.

how do you know when to use which sign

@danthetutor2624 6 ай бұрын

Approaching objects use the top sign, objects going away use the bottom sign

@snowman6199 6 ай бұрын

how do you know when to use a plus sign or a minus sign

@danthetutor2624 6 ай бұрын

For the numerator, it’s + when moving towards, and for the denominator it’s - when moving towards.

My lecturer gave v=336m/s is it correct

@hafsahassan394 19 күн бұрын

Actually that was my query too. Why 343 m/s? We always had 330 m/s as the speed of sound in air.

Thank u ❤

@sunnywu4174 2 ай бұрын

Can you explain the top and bottom part about the signs

@mdsamiralamefti3744 6 ай бұрын

Why not v=332 m/s Sir?😅

@danthetutor2624 6 ай бұрын

Do you mean for the speed of the sound? I use 343 because that’s the speed of sound at room temperature in Celsius.

@@danthetutor2624 Yes, Sir. That was my question. Thanks a lot Sir for clearing my doubt.

someone help I don't know how to put this into a calculator I'm so cooked 😭

@danthetutor2624 12 күн бұрын

Just plug in the numerator and denominator separately. Don’t do it all in one step.

If that’s what your lecturer says, then use that number. I have a feeling it’s for a weird temperature, but I guess that doesn’t matter.
