Use the information below to solve this problem: A note has a wavelength of 0.65551 m. If the speed of sound is 343.00 m/s, what pitch is this note? information below shows v=fa

f=v/a

a=v/f

speed of sound in the air

An incident ray through the focal point of a spherical mirror will: reflect through the center of curvature. reflect back through the focal point. reflect parallel to the principle axis. reflect the same direction as the incident ray.

A1-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. the spring has an undeformed length of 5 in. and a constant k =25 lb/ft. knowing that the collar is released from being held at a determine, the speed of the collar and the normal force between the collar and the rod as the collar passes through b.
