During experiments on laser etching of microchips for IBM, a nuclear engineer places a discshaped sample 5 mm in diameter in a vacuum chamber with surface temperature of 300 K. A 500 mW laser is then used to irradiate the sample uniformly. The sample surface can be considered ‘gray’ with an emissivity of 0.9 and can be considered ‘thin’ so that the disk temperature is uniform. In addition, a non-participating gas at a temperature of 27⁰C is used to cool the sample with a convection coefficient of 50 W/(m2K). Find the steady-state temperature of the disk

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
