When the top of a glass carbonated water bottle is removed, pressure is released and gas bubbles are observed. where did this gas come from?
a. it was dissolved in the water.
b. it was clinging to the inside of the bottle.
c. it formed when the water chemically reacted with the air.
d. it formed when the water physically reacted with the glass.

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.
