There are three basic laws in our study of fluid mechanics: the conservation of mass, Newton's second law, and the first law of thermodynamics.
(a) State an integral quantity for each of the laws and
(b) state a quantity defined at a point for each of the laws.
Four identical charges (+1.6 μC each) are brought from infinity and fixed to a straight line. Each charge is 0.32 m from the next. Determine the electric potential energy of this group.
The volume of an ideal gas is increased from 1 m3 to 2 m3 while maintaining a constant pressure of 1000 Pa (1 Pa = 1 N/m2). How much work is done by the gas in this expansion
