The maximum speed of a 3.00-kg object in simple harmonic motion is 4.00 m/s. The maximum acceleration of the object is 5.00 m/s2. What is the period of simple harmonic motion?

you would expect a sound wave to speed up. - b)

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

vapour or gas assuming atmospheriv pressure
