Increasing the mass m of a mass-and-spring system causes what kind of change in the resonant frequency of the system? (Assume no change in the system's spring constant k.)
A)The frequency increases.
B)The frequency decreases.
C)There is no change in the frequency.
D)The frequency increases if the ratio k/m is greater than or equal to 1.
E)The frequency decreases if the ratio k/m is less than 1.

The resonant frequency of a mass-and-spring system is given by the formula f = (1/2π)√(k/m). Increasing the mass m decreases the value of √(k/m), thus decreasing the resonant frequency.
