Consider a cube with side A of 1.0 m. Assuming that the same mass of cube is converted to cubes with sides of 1.0 um, calculate the increase in surface area.

An enclosure consists of two black surfaces formed by cutting off a 0.3 m diameter spherical shell by a plane at a distance 0.1 m from the centre and closing it by a black circular disk Determine the view factors of the surfaces. in R de

2) Consider two cubes of plastic and wood that are floating in water, each of side s. (see diagram). The density of the plastic is 80.0 % of the density water and the density of the wood is 60.0 % of the density of water. An aluminum block having base area s? is going to be glued on top of the plastic and wood system. The density of aluminum is 2.7 times the density of water. Assume the system stays upright (does not tip over). Alum block a) How tall does the aluminum block need to be if the top of the aluminum block will be at the surface of the water when equilibrium is reached ? Give answer in terms of s. woed water plastic on tup
