One way to look for oil deposits under ground is to lower a source of neutrons and detect how many are reflected back by the surroundings as the neutron source is lowered (not many neutrons reflected implies oil in the surroundings that are absorbing the neutrons.) The decay that produces the neutron is 13Be 12Be + n. The respective atomic masses are 13Be: 13.036135; 12Be: 12.0269221. The rest mass of the neutron and the conversion from atomic mass unit...

A nucleus whose mass is 3.730032 x 10-25 kg undergoes spontaneous "alpha" decay. The original nucleus disappears and there appear two new particles: a He-4 nucleus of mass 6.640678x10-27 kg (an "alpha particle" consisting of two protons and two neutrons) and a new nucleus of mass 3.663533 x 10-25 kg (note that the new nucleus has less mass than the original nucleus, and it has two fewer protons and two fewer neutrons). In these calculations, it is very important to...

series limits (the smallest angle of the series) is 15.0degree. Find the wavelength and photon energy that corresponds with this angle. The energy of the photon in part e) is the maximum energy that can be emitted in this line series. (This corresponds to a transition from an upper value of n = infinity.) What is the lower value of n tor this series? p pis] What transitions do each of the three lines...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
