(a). A Geiger counter registers a count rate of 4,400 counts per minute from a sample of a radioisotope. Fourteen minutes later, the count rate is 1,100 per minute. What is the half-life of the radioisotope? (3.0 points). (b) (i) I‑131 has a half‑life of 8.0 days. A laboratory prepares a sample with an initial activity of 32 mCi. Calculate the activity of the sample after 16 days. (3.0 points) (ii). If the recommended amount for use for a particular patient is 15 mCi but due to insurance approval issues the procedure was delayed for 24 days, can the initially prepared 32 mCi of I-131 be used? Justify your answer with numbers and explanation. (3.5 points)

Given the following piece of code, determine whether we can parallelize this loop or not. If yes, justify your answer. If not, rewrite the code in a way that makes it completely/partially parallel for ( int i = 0 ; i < 100 ; i++){ a [i] = a [i] + b [i]; c [i] = a[i+1] + c [i]; }

(a). The water in the plumbing in a house is at a gauge pressure of 210,000 Pa. What force does this cause on the top of the tank inside a water heater if the area of the top is 0.6 m2? (ignore atmospheric pressure, take g = 9.80 m/s2 and density of water to be 1000 kg/m3) (1.5 points) (b). A large chunk of metal has a mass of 189 kg, and its volume is measured to be 0.07 m3. Find the metal’s mass density and weight density. (3.0 points)

. Alvarez, a handyman, accidentally drops his 500 g work tool from a 12 m high building (take g = 9.80 m/s2) (i). How long does it take for the tool to hit the ground? (1.5 points) (ii). What is the acceleration of the tool just before it hits the ground? (1.0 point) (iii). At what speed does the tool hit the ground? (1.5 points) (iv). What is the mass of the tool just before it hits the ground? (1.0 point)
