Question

at either end of the pool by springs, as shown in Fig.-1. The left spring has a spring constant,
A = 65.0 N/m, and equilibrium length, L1-0.600 m. The spring on the right has a spring
constant, k2-75.0N/m, and equilibrium length, L20.800m

supports at 0.500 m, and let go. How long after it's let go does it take to return to
x- d? (Neglect the drag of the fluid.)

- Parcels of air (small volumes of air) in a stable atmosphere (where the temperature increases with height) can oscillate up and down, due to the restoring force provided by the buoyancy of the air parcel. The frequency of the oscillations are a measure of the stability of the atmosphere. Assuming that the acceleration of an air parcel can be modeled as 2zt2=g(z)0zz , prove that z=z0etN2 is a solution, where N is known as the Brunt-Väisälä frequency. Note that in a stable atmosphere, the density decreases with height and parcel oscillates up and down.arrow_forwardArtificial diamonds can be made using high-pressure, high-temperature presses.

The bob of the pendulum is a 1-ft steel scythe connected to a 30-ft brass rod. When the man first sees the pendulum, the pivot is roughly 1 ft above the scythe so that a 29-ft length of the brass rod oscillates above the pivot (Fig. P16.39A). The man escapes when the pivot is near the end of the brass rod (Fig. P16.39B). a. Model the pendulum as a particle of mass ms 5 2 kg attached to a rod of mass mr 5 160 kg. Find the pendulums center of mass and rotational inertia around an axis through its center of mass. (Check your answers by finding the center of mass and rotational inertia of just the brass rod.) b.
