Q1. Tritium (3H) decays by negative beta decay with a half-life of 12.16 years. Use an atomic weight. What is the mass in g of 1 mCi of tritium? 3.026 For 3H.To what nucleus does 3H decay?

Q2. An underground telephone cable consisting of the pair of identical parallel wires, has suffered a short somewhere along its length. The cable is 5km long and in order to discover where the short is the technician first measures resistance between the ends of two wires at one end of the cable and after that at another end of the cable. (Suppose that nothing is connected to the cable while technician is doing that) The first measurement yields 30.0 Ohm, the second yields 70.0 Ohm. Where is the short? What is the diameter of the wire if it is made of copper?
