Is the object going as fast between 9 and 12 seconds as it is between 1 and 4 seconds? How can you tell? 3. What is the motion of the object between 4 and 6 seconds? acer

The world population in billions is approximately P = 7.4e0.010" where t is in years since 2016. Estimate the relative rate of change of population in 2020 using this model and the values of At below. Round your answers to three decimal places. (a) At = 1 The relative rate of change is % per year. the absolute tolerance is +/-0.001 (b) At = 0.1 The relative rate of change is % per year. (c) At = 0.01 The relative rate of change is % per year.

Q.5. What could be the possible reasons for errors in measurements?

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.
