Kinetic energy of a body is defined in terms of mass and velocity k=½mv². If m=0=352+or-0.001 and v=1.91+or -0.01. calculate k and absolute error

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.)

When solid surfaces slide over each other the kind of friction that occurs is called friction

Five structural isomers have the formula c6h14. where needed, draw the structure and give the iupac name of all five isomers.
