Question

1. Three pies are put in an industrial sized microwave oven with microwave frequency 2.5 GHz. Each is encased in a box of different material, but identical dimensions. Which pie will cook fastest in this oven and why? Aluminum Polystyrene Porcelian 2. a. Related question which of the two rods below will dissipate more power when driven by a 1 volt source at 1.0 GHz? Let their radii be 1.0 cm and lengths 10 cm. b. By how much could you adjust the silver driving frequency so that both rods consume the exact same power. Note: (Au) should be gold ON 1GHz 1 GHz

Explanation / Answer

Aluminium has the melting point of -- 660.3 °C

Polystyrene has the melting point of -- 240 °C

Porcelian has the melting point of -- 3275 °C
