A telescope forms an image of part of a cluster of stars on a square silicon charge-coupled detector (CCD) chip 2.00 cm on each side. A star field is focused on the CCD when it is first turned on and its temperature is 27.0 degrees celsius. The star field contains 5432 stars scattered uniformly. To make the detector more sensitive, it is cooled to -173 degrees celsius. How many star images fit onto the chip? The average coefficent of linear expansion of silicon is 4.68x10^-6 (degrees celsius)^-1
