A wood burning stove is box shaped with a height of 30.7”, width 26.25” and depth 25.5”. The front surface is glass (Ԑ= 0.9) and the other surfaces are cast iron (Ԑ= 0.7). The fire keeps the stove surface at a constant 202 °C.

a.Calculate the rate at which the stove’s one glass surface (30.7” by 26.25”) radiates heat into the surrounding space.

b.Calculate the rate at which the cast iron sides radiate heat into the surrounding space. Add this to your answer to part a) to determine the total rate of radiation into the surrounding space. Assume the stove is raised off the floor so the bottom radiates.

c. If the surrounding temperature is 22 °C, find the net rate of radiative heat transfer from the wood stove to the surroundings

A microwave has a width of 29 inches, depth of 15 inches, and a height of 16 inches. The power of the microwave is 1.65 kW. Use this information to solve these questions. Assume that microwave energy is generated uniformly on the upper surface of the cavity and propagates directly downward toward the base. The base is lined with a material that completely absorbs microwave energy. (c = 3.00 × 108 m/s, μ0 = 4π × 10-7 T ∙ m/A,...

1.) A box made of wood is sitting on a wooden floor. The box and contents has mass 40kg. The coefficient of static friction is 0.50 and kinetic friction is 0.30. A person begins to push the box horizontally by slowly increasing their force until it reaches 160N. Describe the state of motion (if any) of the box and the frictional force acting. 2.) The formula for friction is f=uN, for both static and dynamic friction. What factors that may...
