Answer #1:
Your question cannot be answered without knowing what the pendulum was
filled with before it was filled with Mercury.
If it had nothing in it, before, then adding the mercury would increase the
period time.
If it had lead in it before, then adding the mercury would decrease the period
time.

Answer #2:
The period of a simple pendulum doesn't depend on the weight (mass) of the
bob. As long as the bob is much heavier than the string, and air resistance can
be ignored, nothing you do to the bob has any effect on the period.
The period of a pendulum is affected by the angle created by the swing of the pendulum, the length of the attachment to the mass, and the weight of the mass on the end of the pendulum.
At the extremities of the pendulum's swing, the sand leaving the bob could exert a force on the bob. Provided that this force is negligible and also, provided the mass of the bob (with or without the sand) is large compared with the rest of the pendulum, the time period should not be affected.
In a simple pendulum, with its entire mass concentrated at the end of a string, the period depends on the distance of the mass from the pivot point. A physical pendulum's period is affected by the distance of the centre-of-gravity of the pendulum arm to the pivot point, its mass and its moment of inertia about the pivot point. In real life the pendulum period can also be affected by air resistance, temperature changes etc.
the time period of a pendulum is proportional to the square root of length.if the length of the pendulum is increased the time period of the pendulum also gets increased. we know the formula for the time period , from there we can prove that the time period of a pendulum is directly proportional to the effective length of the pendulum. T=2 pi (l\g)^1\2 or, T isproportionalto (l/g)^1/2 or, T is proportional to square root of the effective length.
The period of a pendulum is totally un-affected by the mass of the bob.The time period of pendulum is given by the eqn.T=2*PIE*(l/g)1/2 ;l is the length of pendulum;g is the acceleration due to gravity.'l' is the length from the centre of suspension to the centre of gravity the bob.ie.the length of the pendulum depends on the centre of gravity of the bob,and hence the distribution of mass of the bob.

The PERIOD of a Simple Pendulum is affected by its LENGTH, and NOT by its Mass or the amplitude of its swing. So, in your case, the Period of the Pendulum's swing would remain UNCHANGED!

A shorter pendulum has a shorter period. A longer pendulum has a longer period.
A longer pendulum has a longer period. A more massive pendulum has a longer period.

Hardly at all, at small displacements or amplitudes. At larger displacements (larger angles), the period will get somewhat longer.
A longer pendulum has a longer period.
Height does not affect the period of a pendulum.
