    i dont think so because the 420 m/s would have been negative so you should have got an answer in the 70s
    Yep, I got 70.8

    Yeah I dont know why I multiplied it by two...made a lot of mistakes on that paper
    I thouhht you did have to multiply it by two as you were multiplying the wavelength by two therefore you have to add the uncertainty twice?

    So I'm going to make a short video tomorrow when I get to see the paper (I can't see it yet as I'm a teacher). Which questions in particular do you want me to work through?

    I personally think depth in physics is gonna be easier not just because of the exam itself but the fact that I have weeks to revise for it. Todays paper I didn't even touch module 4 could only revise module 3. module 4 itself should be a subject alone. I'm pretty confident i got a U today
    Me too!!!!!

    Question-The one about the addition of velocities and masses; was the difference that one was scalar and the other was a vector so for velocity you have to also calculate the direction of the physical quantity; whilst with mass you just find the magnitude.
