Alight water-cooled nuclear power plant rated at 1000 mw(el) would require approximately 3100 mw of thermal input from the fuel. estimate the mass of fuel that has fissioned during a year of operation at 80 percent plant capacity factor. the plant capacity factor is the ratio of energy gen- erated in a given period to the amount that could be produced if the plant operated continuously. note that the mass fissioned is not the loss in mass as a result of fission since each atom fissioned forms fission product nuclides.

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
