Question

3. Calculate, for the judge, how fast you were going in miles per hour when you ran the red light because it appeared Doppler-shifted green to you. Take red light to have a wavelength of 650 nm and green to have a wavelength of 550 nm
Throughout this homework assignment, you may use c to denote the speed of light in both your work and final answers without using its numerical value. (This is actually preferred unless the problem requires the numerical value of c.)

    1. How many successive velocity increments of e are needed to produce a resultant velocity of 0.99e (Hint: You can do this using the standard form of the velocity addition law in the book. But it is easier if you use the fact that, in terms of the rapidities φ,a, a, defined by : ctanho, u-: c tanha, u' =: c tanha", the velocity addition law takes the simple forn。' + φ.

    For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
