The propagation of uncertainty formula for the equation y - ax^2 is y (Ay +(Ay,)² where Aya = (ax²) – ((a + Sa)x²).and .Ayx = (ax?) - (a(x+ 5x)²) and. The values %3D %3D Sa and 5x are the uncertainties on a and x respectively. If a = 0.4 +/- 0.8 and x = -1.6+/-0.7 then what is the uncertainty on y?
2.25 An electron moves with a constant velocity 1.1 × 106 m/s. If the velocity is measured to a precision of 0.1 per cent, what is the maximum precision with which its position could be simultaneously measured?
Lunar astronauts placed a series of cube reflectors on the Moon as part of an experiment to mea- sure the distance to the Moon with hyperaccuracy. Lasers were fired from an observatory in West Texas toward the Moon; they reflected off these cubes and returned to Earth. The time of arrival was measured by astronomers at the observatory. If the time for the round trip could be measured with an accuracy of 0.1 nanoseconds, what was the uncertainty in the measured distance to the Moon. Given that the semi-major axis of the Moon’s orbit is 3.84 x 108 km, what is the percent accuracy of these measurements?
A 64.6 g ball moves at 38 m/s. If its speed is measured to an accuracy of 0.07%, what is the minimum uncertainty in its position? Answer in units of m. S.
An effective treatment for some cancerous tumors involves irradiation with "fast" neutrons. The neutrons from one treatment source have an average velocity of 3.5×107 m/s. If the velocities of individual neutrons are known to within 2.0% of this value, what is the uncertainty in the position of one of them? answer in m
Estimate the uncertainty in the position of (a) a neutron moving at 5 x 10°m/s and (b) a 50 kg person moving at 2m/s

32.(a) How much time is needed to measure the kinetic energy of an electron whose speed is 10.0 m/s with an uncertainty of no more than 0.100 percent? How far will the electron have traveled in this period of time? (b) Make the same calculations for a 1.00-g insect whose speed is the same. What do these sets of figures indicate?
