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.
Most Filipinos live on eleven principal islands that account for 90 percent of the archipelago's landmass. Manila, the capital, is located on Luzon, the largest and most populous of the islands. In 1941 the Philippines formed the westernmost U.S. outpost, 5,000 miles from Pearl Harbor and over 7,000 miles from San Francisco. By contrast, Manila is only 1,800 miles from Tokyo.
