A pendulum consisting of a sphere suspended from a light string is oscillating with a small angle with respect to
the vertical. The sphere is then replaced with a new sphere of the same size but greater density and is set into
oscillation with the same angle. How do the period and maximum acceleration of the new pendulum compare to
those of the original?
