A100 hz sound wave is traveling through the air. if we increase the frequency to 200 hz, this will the wavelength. a 100 hz sound wave is traveling through the air. if we increase the frequency to 200 hz, this will the wavelength. increase decrease not change

What is the length x of the side of the triangle below? (hint: use the cosine function)

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.

Why are graphs useful when interpreting data
