The isomeric 2+ state of 60co at 58.6 kev decays to the 5+ ground state. internal conversion competes with gamma emission: the observed internal conversion coefficients are alphak=41, alphal=7 and alpham=1. compute the expected half-life of the 2+ state if the tranition multipolarity is assumed to be m3 and compare it with the observed half-life. if the transition also contained a small component of e4 radiation, how would your estimate for the half-lif be altered? the 2+ state also decays by direct beta emission to 60ni. the maximum beta energy is 1.55 mev and the log(ft1/2) is 7.2. what is the effect of having this additional mode of decay? how much of each decay would we see and what would happen o the half-life?

A5 foot by 5 foot box culvert is buried 6 feet beneath the surface of the ground. a crosssection of this very long culvert (into and out of the page) is illustrated below. assume that the soil in which the culvert is buried has the following properties: jt = 120 pcf, w = 12%, ko = 0.50, ka = 0.33, and kp = 3.00. calculate the total horizontal force per unit length of culvert (fh) felt on one of the vertical faces of the culvert.

Atank has a shape of a cone with a radius at the top of 2 m and a height of 5 m. the tank also has a 1 m spout at the top of the tank. the tank is filled with water up to a height of 2 m. find the work needed to pump all the water out the top of the spout. (use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)
