Find the work performed when the given force f f is applied to an object, whose resulting motion is represented by the displacement vector d d. assume the force is in pounds and the displacement is measured in feet

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.
