The table shows the percentages of hydrocarbons that are found in a sample of crude oil. hydrocarbons percentage paraffins 30 naphthenes 49 aromatics 15 asphaltics 6 based on the given information, what is the best classification for this sample of crude oil?

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.

How do you tell if someone actually cares about you? and just say they do?

This is the substance(s) formed in a chemical reaction.
