Changing the spring constant also changes the period, if k 2 k 1 then T 2 T 1 For simple harmonic motion the period is independent of amplitude, i.e. extension does not affect the period of oscillation, hence stretching the spring more to start with makes no difference to period.
Manila is located on the northwestern coast of the Philippines. Its population of 1.6 million is divided between a booming business district in Makati City and destitute communities on the fringes. In the poorest regions, multiple families live in close quarters in makeshift communities.
The North Chapter was based in Greenhills, San Juan, the South Chapter remained based in Makati. With this milestone, the BCBP continued to spread its wings the following years with Alabang, south of Metro Manila, being established, followed by Dagupan up in the northwestern Luzon region in 1986.
