A solar thermal power tower is rated to produce 10 MW of power using a steam turbine. The thermal energy will be collected using 1 106 kg of molten nitrate salt as the thermal reservoir with a heat capacity of 1.5 kJ/kg K. The salt can be heated to a maximum of 565 oC and heat can be removed from the salt to a minimum of 265 oC

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.

True or false graphs must include scales that increase by the same amount
