1)A missile protection system consists of n radar sets operating independently, each with probability 0.9 of detecting an aircraft entering a specified zone. (All radar sets cover the same zone.) If an airplane enters the zone, find the probability that it will be detected if a) n = 2 b) n = 4 c) How large must n be if it is desired to have probability 0.99 of detectingan aircraft entering the zone?

A neutron is confined in a deuterium nucleus (deu- teron) of diameter 3.1 X 10-15 m. Use the energy- level calculation of a one-dimensional box to calcu- late the neutron's minimum kinetic energy. What is the neutron's minimum kinetic energy according to the uncertainty principle?
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?

Find the approximate solid angle for a source-detector arrangement whereby a 5-cm diameterdetector is placed 30-cm from a point source which emits gammas isotropically. Formally, onewould find a solid angle by integrating sinθ dθ dφ over appropriate θ and φ limits given by thesize of the detector at the given distance from the source. However, a good approximation is touse the ratio of the detector area to the surface area of a sphere at the detector distance to findthe fraction of 4-pi which the detector covers
