Abook is pushed and released and it slides across a table for a short distance. the book quickly comes to a stop. the book originally has kinetic energy. to what form of energy is the kinetic energy transformed?

potential energy , friction , heat and sound , but if we are talking about a direct transfer then it is potential energy .

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
