Which of the following is the formula for the period of a simple pendulum in simple harmonic motion?

• T = 2π√L/a_g

• T = 2π√a_g/L

• T = √L/a_g

• T = 2π√a_g•L

True of False: In a mass-spring system, greater spring constant → shorter periods

• True

• False

True or False: In a mass-spring system, lower spring constant → longer periods

• True

• False

Which of the following is the equation for the period of a mass-spring system in simple harmonic motion?

• T = 2π√m/k

• T = 2π√k/m

• T = 2π√m•k

What is a wave?

• A disturbance that propagates through a medium

• A disturbance that propagates an object through a medium

• A medium that propagates through a disturbance

• A frequency that propagates through a solid

What is a medium?

• A physical environment through which a disturbance can travel

• An abstract environment through which a disturbance can travel

• A physical environment through which a disturbance cannot travel

• A physical environment that travels through a disturbance
