    Good sir! You likely won't see this, but I just wanted to say thank you so much :) I have my last science paper tomorrow, and I've watched your videos over the past two years. Every time I don't understand something, you've been able to explain it in a clear and simple way - you've never failed to help me. I found your videos on chemical calculations, refraction and the required practicals so very useful. You are genuinely an inspiration and the kindest of souls - you've helped so many of us over the years, and you definitely deserve a medal of some description.. So.. Three cheers for the best science teacher out there! 💥💥

      @arakurd6351 5 років тому +32

      @@bigmanc3217 its bidmas - multiplication and division always come first so 10x10 = 100. After that, we don't do adding, we do dividing instead so +10/10 = +1 (in maths you always keep the sign to the left of the number with it - if it was 10x10-10/10 then we would've done -10/10). Next is 100+1 which equals 101 so thats how 10x10+10/10=101

    Sir I'm a bit confused. Why when measuring wavelength for longitudinal wave you measure from centre of each rarefraction or compression, not from the beginning. Like the arrows you put where all starting from middle of each. I hope you can reply in time before exams sir

    • @Freesciencelessons
      @Freesciencelessons  Рік тому +2

      You can measure from anywhere (start, middle or end) as long as you always measure there. You cannot measure from the start of a compression to the middle of the next compression for example.

    • @beanmachine1248
      @beanmachine1248 7 років тому +14

      in an animal species, animals with genes that benefit them (like a longer neck on a giraffe or a more camouflage rabbit) allow them to survive longer. meaning that ones without that gene will die off leaving the advantaged animal to reproduce and pass its gene on through the whole species allowing it to evolve. i think

    • @Freesciencelessons

      Divide the number of waves by the number of seconds. That will give you number of waves / second, which is frequency.
