The acceleration of particle is defined by the relation a= -k/x. It has been experimentally determined that v=15 ft/s and x=0.6 ft and that v=9 ft/s when x=1.2 ft. Determine (a) velocity of the particle when x=1.5ft (b) Position of the particle at which its velocity is zero.

Machinery that is a key part of the process and without which the plant or process cannot function is classifed as: (clo4) a)-critical machinery b)-essential machinery c)-general purpose machinery d)-none of the specified options.

Agas mixture consists of 8 kmol of h2 and 2 kmol of n2. determine the mass of each gas and the apparent gas constant of the mixture.
