Water is called the “universal solvent.” which statement best explains this description with respect to ionic compounds?
a. water can dissociate all ionic compounds through ion-dipole interactions.
b. water can hydrate many ionic compounds through hydrogen-bonding interactions.
c. water can dissociate many ionic compounds through ion-dipole interactions.
d. water can hydrate many ionic compounds through dipole-dipole interactions.

Aparticle of mass m is projected with an initial velocity v0 in a direction making an angle α with the horizontal level ground as shown in the figure. the motion of the particle occurs under a uniform gravitational field g pointing downward. (a) write down the lagrangian of the system by using the cartesian coordinates (x, y). (b) is there any cyclic coordinate(s). if so, interpret it (them) physically. (c) find the euler-lagrange equations. find at least one constant of motion. (d) solve the differential equation in part (c) and obtain x and y coordinates of the projectile as a function of time. (e) construct the hamiltonian of the system, h, and write down the hamilton’s equations (canonical equations) of motion.
