our little sister builds 2 tree houses and stretches a rope between them for sending messages to other tree house. She hangs a mass of 1.4kg on one end of the rope that passes over the pulley.
Engineers can determine properties of a structure that is modeled as damped spring oscillator-such as a bridge-by applying a driving force to it, What is the oscillator\'s damping constant? (kg/s)
Identical objects are located at the same distance from two spherical mirrors, A and B. Find the ratio fA/fB of the focal lengths of the mirrors
