The 45-g Wood Thrush migrates every spring from Central America to the United States to breed. The bird leaves its winter home in Belize and travels 1422 km across the Gulf of Mexico to Louisiana. It then flies an additional 1343 km to reach
Virginia, where it spends the summer. The trip takes approximately 171 hours, flying mostly at night.
What is the average speed of the Wood Thrush?

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
