Liquid water at 300 kpa and 20°c is heated in a chamber by mixing it with superheated steam at 300 kpa and 300°c. cold water enters the chamber at a rate of 2.4 kg/s. if the mixture leaves the mixing chamber at 60°c, determine the mass flow rate of the superheated steam required. (round the final answer to three decimal places.)

Which of the following statements comparing electron microscopy and light microscopy is false? which of the following statements comparing electron microscopy and light microscopy is false? both the electron microscope and the light microscope use the same wavelengths for illumination. images produced by light microscopes can be in color, whereas electron microscope images are black and white unless they are artificially colored. the electron microscope has greater resolution than the light microscope. electron microscopes can allow examination of viruses and internal cell structures, whereas light microscopes are limited to objects that are 0.5 micrometers and larger. request answer

The brightest star in the night sky in the northern hemisphere is sirius. its distance from earth is estimated to be 8.7 light years. a light year is the distance light travels in one year. light travels at a speed of 3.00 × 108 m/s. calculate the distance from earth to sirius in miles.
