Conceptual - Mass, Period, Spring Constant

[sheri1987]

Homework Statement

True or False

Quadrupling the mass will double the period.
Tripling the amplitude will sextuple the frequency.
Doubling the amplitude will not change the frequency.
Halving the amplitude will quadruple the frequency.
Doubling the spring constant will halve the period

Homework Equations

w=(2pi)frequency
*mass has no role in the period

The Attempt at a Solution

I put
False
False
False
True
False

What am I doing wrong?

 

[Astronuc]

The mass and spring constant most certainly do affect the period.
