A heterogeneous mixture is usually defined as a combination of two or more chemical substances. It can be also elements as well as compounds. These contrasting components can be easily separated from one another by means of physical process. These are comprised of substances that are not even everywhere. There is variation in it.
Thus, the correct answer is option (B).
It is given that the height of the tower is

The uncertainty the measurement of this height is

Drop time is measured as:

The uncertainty in measurement of time is:

Using the equation of motion:
where,
is the distance covered,
is the initial velocity,
is the acceleration and
is the time.
(because canon ball is in free fall). we need to calculate the value of a=g.


The uncertainty in this value is given by:

Substitute the values:

The object is fixed relative to the motion you are trying to describe.
