1. Using the equation h i /h o =s j /s os the height of an image in a mirror. The box is placed 1.5 meters in front of the mirror and the image will form .09 behind the mirror. The box is 2 meters high . Find the height of the image and select if it's a virtual or real image.

Athin, square metal plate measures 14 cm on each side and has emissivity of 0.60. the plate is heated to a temperature of 745°c. what is the rate at which the plate radiates energy ? the stefan-boltzmann constant is 5.67 × 10-8 w/(m2 ? k4). remember that the plate will radiate energy from both its top and bottom surfaces.
