Your town is considering building a hydroelectric power plant. describe at least two advantages and two disadvantages of this project. based on these factors would you recommend that they continue with the project or consider other options?

Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.

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.

If an electric circuit is not grounded it is best to reach out and touch it to provide the ground a.true or b.false
