during photosynthesis plants transform the energy in sunlight into chemical energy by converting molecules of carbon dioxide and water into sugar and oxygen molecules what are two reasons scientist might use a model to represent what happens during photosynthesis

Which type of microscope would allow the viewer to see ribosomes inside a cell?

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.
