Question

Take a 1 m long thread of negligible mass. Consider three spherical/ cuboidal bobs of
same sizes but different masses. Form simple pendulum using thread and bob, and estimate
the time period of each of the pendulum by recording time for 20 oscillation three times
for each pendulum formed. Tabulate the observations taken. Interpret your results and
justify. List your 2 main conclusions derived from the above project.

Answer 1

In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers. ... For example, the decimal representation of π starts with 3.14159, but no finite number of digits can represent π exactly, nor does it repeat.
