It is proposed to produce 25 kg of 90 w/o enriched uranium for a submarine reactor by enriching 20 w/o fuel from a research reactor. (a) how much fresh reactor fuel would be required? (b) compute the total swu required. (c) compare the swu/kg required to produce 20 w/o fuel starting from natural uranium, with 90 w/o material beginning at 20 w/o (tail enrichment = 0.2 w/o).

If a sphere and a cure have the same mass and are propelled up a ramp with the same force, which would travel father up the ramp? explain.

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
