The international space station revolves around earths surface. which of the following statement s is true ? a. it has no energy because it is stationaryb. it has potential energy , but does not have kinetic energyc. it has kinetic energy , but does not have potential energy. d. it has both potential energy and kinetic energy.

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
