Question:
The earth's free-fall acceleration varies from 9.78 m/s2 at the equator to 9.83 m/s2 at the poles. A pendulum whose length is precisely 1.000 m can be used to measure g. Such a device is called a gravimeter.
a. How long do 100 oscillations take at the equator?
b. How long do 100 oscillations take at the north pole?
c. Suppose you take your gravimeter to the top of a high mountain peak near the equator. There you find that 100 oscillations take 201 s. What is g on the mountain top?

I teach calculus, communication skills, mechanics and economics. I am also a home tutor. My student Muhammad Salman Alvi is a brilliant A-level student and he performs very well in academics when i start to teach him. His weak point was mathematics but now he is performing well in mathematics. I am a scholarship holder in Fsc as i scored 1017 marks in metric out of 1100. Later on i got scholarship in Punjab Group of Colleges. I got 2nd position in robotics competition in 2018 as my project home automation select for the exhibition in Expocentre.
