Radiometric dating of a sedimentary rock sample shows an age of 1.5 million years. what conclusions can be drawn from this data? the rock is a minimum of 1.5 million years old but it may be older. radiometric dating cannot be used on sedimentary rock so no conclusions can be drawn. the rock is a maximum of 1.5 million years old but it may be younger. the rock is exactly 1.5 million years old.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
