In the 1980's, Congress authorized the U. S. Department of Energy to build the WIPP facility in the Chicuahuan Desert in New Mexico. What is the purpose of WIPP? A) storage of nuclear waste from nearby nuclear power plants B) educating tomorrow's nuclear scientists on nuclear issues C) storage and disposal of the nation's transranic radioactive waste D) research and development of bigger and better ways to utilize nuclear power

Given the position vector of the particle r(t)=(t+1)i+(t^2−1)j+2t k, find the particle's velocity and acceleration vectors at t=1

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)
