- The followings are the measurements from one group of students: M1=127.01 g, M2=49.40 g, Xi=33.90 cm, Xf=87.90 cm, Δt = 1.38 sec, what should be their μk value? Enter the result with correct significant figures.The rate of decay of the radioactive isotope Free Neutron 239 is given by: M = -1.1 x 10-³M where M is the mass of the isotope in grams and t is time measured in minutes. A sample initially contains 3 grams of the isotope. What is the mass of the isotope present in the sample after 320 minutes? The mass is grams. Round your answer to 3 significant figures, if needed. b) How long does it take for the mass of the isotope in the sample to fall to 1.5 gram? It takes t = minutes. Round your answer to the nearest integer if needed.ect.mheducation.com%: Saved Help Required information A bowling ball made for a child has 1/2 times the radius of an adult bowling ball.
